Two experimental trials were carried out in the two successive seasons of 2014and 2015 to investigate the effect of five NPK fertilizers levels and foliar spraying with some micronutrients on cowpea plant. The experiment consisted of five treatments of fertilizers levels (50%, 75%, 100%, 125%, and 150% RDF) of NPK and three rates of mixtures of (6%Fe, 5% Zn and 1% B)beside a control. A split plot in a randomized complete blocks design with three replicates was used. Results can be summarized as follows: increasing applied fertilizer NPK at rate from (50% to 150 % RDF) lead to significantly increase in plant height, plant fresh and dry weight, leaf area/plant chlorophyll b content as well as seed yield and its components, i.e., seed yield/plant, seed yield/fed, number of pods/plant, number of seeds/pod, pod length and weight of 100-seeds weight and some chemical content of plant and seeds of cowpea. But the higher values were recorded after application with use applied fertilizers at rate 100%RDF in the two seasons. On the other hand spraying cowpea plant with(6% Fe, 5% Zn and 1% B)mixture significantly increased all the previous traits in all experiment investigated compared with control (without foliar).The foliar mixture(6% Fe, 5% Zn and 1% B) gave a superior value in both seasons. Since; it produced the highest values of plant height, number of leaves/plant, number of branches/plant, leaf area/plant, seed yield and its components and percentage of crud protein of seeds content. According to the mentioned results, the recommendation is application of NPK at rate 100%RDF with foliar mixture of micronutrients at rate 3g/l three times so as to give the highest cowpea seed yield and its quality.

To investigate the interaction between salinity stress and seed priming with acetyl salicylic acid on sweet pepper seed germination and early growth, two factorial experiments were carried out during the two seasons 2014 and 2015. A lab experiment involved seed priming in four different concentrations 0.0, 0.1, 0.3 and 0.5 mM of acetyl salicylic acid, the performance of primed seeds was assessed under 4 different salinity levels 0, 30, 60, and 90 mM NaCl. The second experiment was carried out in foam transplanting trays under greenhouse conditions. Primed seeds were irrigated with 0, 30, 60, and 90 mM NaCl solutions. The obtained results showed that salinity reduced germination percentage, delayed germination, and reduced seedling and transplant growth parameters. Nutrients uptake was reduced by salinity increasing. Different concentrations acetyl salicylic acid had relieving effect. Among all concentration 0.3 mM acetyl salicylic acid was the best concentration in most cases.

A line x tester analysis involving 28 top-crosses generated by crossing seven elites maize inbred lines (yellow) with four testers (yellow single crosses) was conducted for different some traits during 2015 cropping season at the Experimental Farm of Agricultural Faculty, Mansoura University, Egypt. The experimental design was the Randomized Complete Block Design (RCBD), with three replications. The objectives of this study were to estimate of general and specific combining ability effects of the parents (the inbred lines and the testers) and to evaluate the top-crosses performance of the hybrids for flowering, vegetative and ears yield plant-1 traits. The GCA/SCA ratio was found to be less than unity in all studied traits under both conditions, except ear height under stress condition, revealing that non-additive gene effects were more important than additive gene effects in the expression of these traits. Results showed that line (1), line (2), line (6), tester (1) and tester (2) were the best general combiners among the parents for ears yield per plant. Top-crosses no. 3, 4, 7, 9, 13, 20 and 26 under both conditions, 10, 19, 21, 22, 27 and 28 under water stress condition and 14, 23, 24 and 25 under normal irrigation condition showed negative and highly significant specific combining ability estimates for tasseling date. Top-Crosses no. 3, 4, 7, 9, 10, 13, 20 and 26 under both conditions, 19, 21, 22 and 28 under water stress condition and 6, 8, 23, 24 and 25 under normal irrigation condition showed negative and highly significant specific combining ability estimates for silking date. Negative and significant or highly significant specific combining ability estimates were detected for top-crosses no. 1, 11, 16, 19 and 26 under stress condition for ear height. Significant or highly significant and negative specific combining ability estimates were detected for top-crosses no. 1, 6, 9, 16 and 20 under stress water condition and 7, 12 and 13 under normal watering condition for plant height. Highly significant and positive specific combining ability estimates were detected for top-crosses no. 3, 4, 10, 13, 17 and 24 under stress water condition, 1, 2, 9, 16 and 20 under normal water condition and 5, 8, 11, 15, 18, 22, 25 and 26 under both water conditions for ears yield per plant.

The present study investigation was carried out at the Experimental Farm of Rice Research and Training Center (RRTC), Sakha, Kafr El-Sheikh, Egypt, during the three successive growing seasons of 2014, 2015 and 2016. Four rice genotypes namely; Sakha 101, Sakha 102, Sakha103 and Sakha 104 were used as Lines and four monogenic lines; i.e., IRBLKS-S, IRBL3-CP4, IRBL5-M and IRBL7-M, were used as Testers, which cried blast resistance genes Pik-s, Pi3, Pi5(t) and Pi7(t). Under field condition, the results showed that the varieties Sakha 102 and Sakha 103 were resistant to blast under the three locations, Sakha, Gemmiza and Zarzoura. On the contrary, the other two Egyptian varieties Sakha 101 and Sakha104 were susceptible. Moreover, the monogenic lines (IRBLKS-S, IRBL3-CP4, IRBL5-M and IRBL7-M) were blast resistant under natural infection conditions. On the other hand, under five artificial inoculations races IA-77, IG-1, ID-15, IC-17 and IB-45 of Magnaporthe grisea, the results revealed that Sakha 102 and Sakha 103 variety were resistant to all races, except IB-45 race, which were susceptible. While, the two Egyptian varieties, Sakha 101 and Sakha 104 were susceptible to blast of the five races. For monogenic rice genotypes, results showed that IRBLKS-S, IRBL3-CP4 and IRBL5-M which carried (Pik-s, Pi3 and Pi5) blast resistance genes were resistant to all races, except EG-5 race, which were susceptible and the other rice monogenic line IRBL7-M which carry Pi7(t) was resistant against IG-1, 367 and 374 races and susceptible under EG-5 and IB-45 races of M. grisea. The results also suggested that the six major genes; Pi-i, Pi-sh, Pik-s, Pi3, Pi5, Pi7 (t) were effective under Egyptian conditions and can be used for improving blast resistance character in breeding program. The results of the inheritance of blast resistance using sixteen F1 and F2 rice populations showed that all F1s were resistant to blast. Among the F2 segregating generation eight populations showed resistant and non-segregation ratio, four rice crosses gave segregations 15 resistant (R) : 1 susceptible (S), while the segregating ratio of another four crosses were 3 R : 1 S for blast. In addition, the analysis of variance revealed significant differences among genotypes, lines, testers and line x tester interactions for blast reaction, duration, plant height, panicle length and weight, flag leaf area, number of panicles/plant and primary branches/panicle, 1000-grain weight and spikelet fertility % traits, indicated that the genotypes had wide genetic diversity for the studied traits. However, significant differences due to interactions of line x tester for the above mentioned traits, indicating the importance of both additive and non-additive gene action in the inheritance of these traits. Highly significant and desirable heterosis and heterobeltiosis were recorded in Sakha 103 X IRBL5-M for improving blast resistance, plant height, flag leaf area, number of panicles/plant and spikelet fertility %. In addition, Sakha 102 X IRBLKS-S rice hybrid was the best cross combinations for early maturity, shortness, area of flag leaf, number of panicles/plant and 1000-grain weight traits and it could be used in breeding program to improving these characters in rice

The experiment was carried out at the Baramoon Experimental Research Farm, Dakahlia Governorate, Egypt, during 2015 and 2016 seasons. The aim of this research was to study the effect of potassium sulfate and calcium borate as soil and foliar fertilization on improving the quality and flower production of Dahlia pinnata, L. plants. Different levels of potassium sulfate at 10 and 20 g/plant as soil fertilizer and calcium borate at 5 and 10 cm/L as foliar fertilizer and companions between them were used. The soil and foliar fertilizers were applied 3 times during the growing period. The results indicated that the combined treatment of 20 g/plant potassium sulfate + 10 cm/L calcium borate significantly increased vegetative growth parameters i.e plant height, number of leaves, number of shoots, stem diameter and dry weight % of plants. It also induced an increment in flowers and tubers parameters (No. of flowers, flower diameter, flower stem length and diameter and flower adherence strength, vase life, No. of tubers/plant and tuber diameter compared with the other treatments used. Total carbohydrates and lignin (%) in flower stem were significantly increased as a result of different fertilization treatments compared to the control treatment. Application of potassium sulfate at 20 g/plant + calcium borate at 10 cm/L was superior to other treatments under this study.

This study was aiming to investigate the effect of different salinity levels, salicylic acid (SA) concentrations and their combination on plant growth, volatile oil production, physiological and biochemical characters of rosemary. Plants were treated with salinity levels at 0, 25, 50 and 100 mM NaCl and SA concentrations as 0, 0.2 and 0.4 mM. Plants responded to salinity via significant reduction in growth as well as relative water content (RWC) against control treatment. Salinity had no effect on volatile oil yield, even though the volatile oil % was increased. Also, salinity decreased total chlorophyll content and enhanced other Physiological and biochemical parameters as well as antioxidant enzyme (CAT, SOD and POX) activities comparative to unstressed plants. The % of N, P, and K were declined within salinity increase. In the meantime, Na and Cl were gradually increased in response to salinity level increase. SA foliar application alleviated the abovementioned salinity deleterious effects on growth, volatile oil production and the physiological and biochemical characters investigated.

Two field experiments were carried out at El-Gemmeiza Agricultural Research Station, El-Gharbia Governorate during the two successive seasons of 2015 and 2016. These experiments were conducted to find out the proper irrigation interval and the effect of natural material which reduce the negative effect of water stress as well as their interaction on leaf chemical composition, growth, flowering habit, earliness parameters, seed cotton yield and its components and fiber quality of the Egyptian cotton cultivar Giza 86. A split plot design with three replicates was used in both seasons, where the main plots were assigned to three irrigation intervals (15, 30 and 45 days) and the sub-plots contained natural materials (without, glycine betaine (600 ppm), potassium citrate (3g/l) and salsalic acid (200 ppm) The important results could be summarized as follows: Irrigating intervals gave significant effect on leaf total chlorophyll, carotenoids, phenols and proline content at 114 days, when irrigated every 45 days followed by irrigated every 30 and 15 day in a descending order. Irrigation every 15 days significantly increased plant height at harvest, number of fruiting branches/plant, number of flowers/plant, boll weight and decreased setting and earliness percentages in both seasons as compared with the other two irrigation intervals (every 30 and 45 days). However, the higher number of open bolls/plant and seed cotton yield / fed were obtained from plants which irrigated every 30 days. Irrigation intervals had insignificant effect on seed index and significant effect on lint % in both seasons. The highest value of lint % was resulted from irrigated plants every 45 days. Spraying with natural materials significantly affected leaf total chlorophyll, phenols and proline content, in favor of spraying potassium citrate and significantly affected leaf carotenoids content at, in favor of spraying salsalic acidSpraying with natural materials significantly affected boll weight and number of open bolls/plant in both seasons in favor of spraying glycine betaine and potassium citrate. Application of salsalic acid or glycine betaine gave significant increase in lint % and insignificant effect on seed index in both seasons. Spraying cotton plants with glycine betaine lead to a significant increase in seed cotton yield per fed.Untreated Plants caused a significant increase in plant height at harvest and number of fruiting branches/plant in both seasons as compared with the plants which received glycine betaine, potassium citrate and salsalic acid. Concerning the interaction between irrigation intervals and natural materials, there is a significant interaction effect with regard to leaf total chlorophyll, carotenoids, phenols and proline contents, in favor of irrigated cotton plants every 45 days and spraying with potassium citrate for leaf total chlorophyll, phenols and proline contents and in favor of irrigated cotton plants every 45 days and spraying with salsalic acid for leaf carotenoids content. Irrigation every 30 days and spraying with potassium citrate produced the highest values of lint % in both seasons. The interaction gave insignificant effect on seed index, Presley index and micronaire reading in both seasons. The combined treatment of irrigation interval every 30 days when combined with glycine betaine at the concentration (600 ppm) gave significant increase in seed cotton yield / fed (kentar) in both seasons. The flowering curve in irrigation every 30 and 45 days was higher, start earlier and ending earlier as compared to the flowering curves in the irrigation every 15 days. It could be concluding that irrigation cotton plants every 30 days in combination with spraying with glycine betaine (600 ppm) or potassium citrate (3g/l) three times (at the squaring stage, flowering stage and at the top of flowering) under El-Gemmeiza condition). Also, it could be concluding that irrigation every 45 days in combination with glycine betaine (600 ppm) at the end of water sources and water shortage.

The limitation of water resources and remarkable increase in population should force research workers to find ways for saving water without significant reduction in yield. So, two field experiments were carried out at Water Management Research Station, El-Karda and Irrigation Development Area at El-Wazaria, Kafrelsheikh, Egypt, during the two growing seasons of 2013/14 and 2014/15 to study the mutual effect of withholding irrigation and potassium fertilizer on yield and water productivity of wheat. Split plot design with four replicates was used. The main plots were devoted to irrigation treatments while the subplots were assigned to potassium fertilizer. Irrigation treatments were full irrigation (W1) including tillering (T), Jointing (J) , booting (B), heading (H) and milking (M) stage, and it has been added to a 60 cm of the root zone depth; full irrigation (W2) including T,J,B, H and M stages, and it has been added to a 40 cm of the root zone depth; withholding irrigation (W3) at M stage; withholding irrigation (W4) at B stage; withholding (W5) at J stage; withholding (W6) at J and B stages and withholding (W7) at J,B and M stages. All withholding irrigation treatments were irrigated to a 40 cm of the root zone depth. Potassium application treatments were 24 kg K2O feddan as basil along with foliar spraying twice using 2 % of potassium sulphate at 35 and 55 days after sowing and control treatment without application. Results showed that insignificant increases between full irrigation treatments of W1 and W2 in spike No. m-2, spike length, kernel No. spike-1, 1000-kernel weight, grain weight spike-1 , straw and grain yields in both seasons .No significant differences in the most of these traits were noticed among withholding irrigation treatments of W3, W4 and W5 that received four irrigation and W1 especially in the first season that receive irrigation twice because of high rainfall. Seasonal water applied amounted 2517, 2025, 1815, 1722, 1758, 1456 and 1246 m3/fed. and water consumptive use values were 1584, 1480, 1327, 1234,1270, 967 and 755 m3/fed. over the two seasons for W1, W2,W3,W4,W5, W6 and W7, respectively. Withholding irrigation treatments of W7 resulted in the highest water productivity to be 2.5 kg grain m-3 over both season. Application K fertilizer (K1) significantly increased straw yield and grain yield and its components except spike length. The interaction between irrigation treatments and K fertilizer had significant effect on the most studied traits in both seasons. Application of K fertilizer diminished the negative effects of withholding irrigation on yield and its components. Application of K fertilizer did not effect on seasonal irrigation water and consumptive use, but it increased water productivity through increasing grain yield. At North Delta, Penman Monteith equation can be used in determining the actual consumptive use and the average of crop Coefficient (Kc) for the two seasons was found to be 0.87, 1.07, 1.11, 1.17, 1.23, 1.28 and 0.35 during emergence, tillering , jointing, heading, milking and ripening stages, respectively. Therefore, when water is becoming a limited factor for wheat production, it should applied withholding irrigation at J or M stages with potassium fertilizer to reduce the negative effect of withholding irrigation at some growth stages and to keep the productivity without significant reduction.

In order to determined of 6 bread wheat varieties representing different traits were crossed in a half-diallel in 2013/2014 season. The 6 parents and its15 F1 crosses were evaluated under normal watering and water stress conditions in 2014/2015 season the objective of this investigation was aimed to study the combining ability and mode of gene action for some wheat traits under normal and stress conditions. Mean squares of genotypes were highly significant for all the studied traits. Both GCA and SCA variances were found to be highly significant for most traits under investigation at both conditions, indicating the importance of additive and non-additive effect in determining the performance of these characters. The ratio of GCA/SCA at the two conditions were more than unity for all studied traits, except heading date and flag leaf area under normal condition, and biomass yield per plant at water stress condition. This indicates that these traits are predominantly controlled by additive gene action, and it could be concluded that selection based on the accumulation of additive effects would be more effective in the early generations. P5 (Sids 14) at normal, P6 (Misr 2) under stress and combined data showed the highest biomass yield /plant. Among crosses, cross No. 12 (P3 x P6) under normal and combined data and cross No. 14 (P4 x P6) under stress showed the highest biomass yield /plant. P1 (Giza 168) and P2 (Sakha 93), at both normal and stress conditions were the best combiners for days to heading (earliness). P6 (Misr 2) was the best combiners for biomass yield per plant under both conditions. The best cross combinations for heading date (earliness) were crosses No. 1 (P1xP2), No. 6 (P2xP3) No. 10 (P3xP4) and No. 15 (P5xP6) at normal condition, crosses No. 5 (P1xP6) and No. 9 (P2XP6) under stress condition, and cross No. 2 (P1xP3) under both conditions. Also, the best cross combinations for biomass yield per plant were crosses No. 3 (P1xP4), No.8 (P2xP5) and No.15 (P5xP6) at both conditions, No. 10 (P3xP4) at normal watering condition, and No. 4 (P1xP5) and No. 14 (P4xP6) at water stress condition.

A pot experiment was carried out during successive seasons of 2015 and 2016 to investigate the effect of water stress on growth, nutritional and biochemical status of two pomegranate seedlings (Early 116 and wonderful) as in Egypt. The experimented seedlings were obtained from cuttings of two pomegranate varieties, namely Early 116 as well as wonderful. One year old pomegranate seedlings were grown in pots filled with sandy soil under greenhouse conditions, where they subjected to four water levels, 100% of field capacity (control), 80%, 60% and 40% of available water. The results indicated that the maximum values of vegetative growth parameters (shoot length, number of sprouted shoots as well as leaf surface area) were obtained when the plants were irrigated with 100 % of field capacity, while the minimum values were recorded at 40 % of available water. Wonderful seedlings gave the highest values of tested growth parameters at all water levels as compared with Early 116 variety. The decrease in irrigation water levels led to increase the hard leaf character, proline content, while leaf succulence grade and relative water content were increased by increasing the given amount of irrigation water in both pomegranate varieties. Although the two tested varieties accumulated high values of proline in their leaves when subjected to water stress (80%, 60% and 40% of available water), but the Wonderful variety accumulated high values of proline content under water stress treatments as compared with Early 166 variety . Therefore, Wonderful variety might be more tolerant to drought than Early 116 variety. The content of some macronutrients (N, P and K %) and micronutrients (Fe, Zn, Mn and Cu mg/kg) in leaves of both varieties were decreased by decreasing irrigation water levels. The highest significant values of some macro and micronutrients were found with control treatment (100 % field capacity), while the lowest values of these nutrients were found at sever water stress (40 % available water).On the other hand, Wonderful seedlings significantly showed a higher content of N, P, K, Fe, Zn, Mn and Cu under all water irrigation treatments than those of Early 116.

Present study was designed to evaluate the performance of newly developed tomato advance genotypes and to investigate their yield stability across a range of environments over two consecutive years. Ten genotypes (8 new promising lines and two check cvs were grown at five different environments. in a randomized complete block design with three replications to determine the Phenotypic and genotypic stability. These Egyptian environments were Kaha, 2015 (Kalubia Governorate); Kaha, 2016 (Kalubia Governorate); El Tal El Kabier, 2015 (Ismailia Governorate); El Tal El Kabier, 2016 (Ismailia Governorate) and Dokki, 2016 (Giza Governorate). Combined results showed that line Z5 produced significantly high mean values for each of earliness, fruit firmness and fruit yield than other studied genotypes, ranked first over all sites in both years andexhibited average stability and it can be recommended for favorable environments. It was concluded that both promising lines G3 and Z3 exhibited high stability of yield and both total soluble solids and fruit firmness where the regression coefficient (bi) was near unity with low deviation from the regression (non-significant, S2di). Therefore, both genotypes G3 and Z3 were found to be the most stable genotypes for all the environments and strongly recommended for planting at multi location trials. A2, Super strain-B, Z42 and G5 are considered as genotype with low stability. G5 appeared to be more productive under unfavorable environments for plant height, days to flowering, fruit firmness, fruit length, fruit diameter, No. locules/fruit, fruit weight and fruit yield.

This study was carried out for two successive seasons (2013&2014) in a private vineyard located at Aga – Dakahlia Governrate to evaluate the efficiency of some new alternatives on dormancy breaking of Flame Seedless grapevines. The chosen vines were 5 years old, grown in a clay loam soil, spaced at 2x2.5m , irrigated by flood irrigation system .The vines were pruned during the second week of January for the two seasons of the study to obtain bud load of 72 buds/vine (6 canes x 12 buds/cane)and sprayed on the third week of January by phosphoric acid 2%, sulphoric acid 2%, potassium nitrate 5%, potassium hydroxid 1%, zinc sulfate3%, urea10%, H2O2 1%, dormex 4% and mineral oil7%. The result show that all treatments hastened the beginning of bud burst and significantly shortened the duration of bud burst rather than the control treatment. Dormex at 4% was most effective as it gave about 95% bud burst.

Two filed experiments were conducted during 2015 and 2016 seasons at the Research Farm of El-Sirw Agricultural Research Station, Damietta Governorate, Egypt. The experiments were performed to study the response of Giza179 rice cultivar to eight nitrogen sources Viz; ammonium sulfate (AS), ammonium nitrate (AN), urea (U), Di-ammonium phosphate (DAP), mono ammonium phosphate(MAP), calcium ammonium nitrate (CAN), and calcium nitrate (CN) and potassium nitrate (KN) under saline sodic soil conditions. The experimental soil was clay with salinity level 7.5 and 7.3 dSm-1 and sodicity (ESP) level 41and 40% dSm-1 in 2015 and 2016 seasons, respectively. The experiment was performed in randomized complete block design and repeated four times. The main obtained results could be summarized as follows; The nitrogen source had significant differences on nutrients leaf contents (NPK), rice growth (leaf area index, dry mater production and chlorophyll content), yield attributes and grain yield in both seasons. Ammonium sulphate showed good and better regarding nitrogen leaf content, while, CAN and KN recorded the highest values of K leaf content. However, DAP and MAP recorded the highest values of P leaf content in both seasons. Ammonium sulphate recorded the highest values of studied growth traits while, the sources contain nitrate (AN, CAN, CN and KN) had the lowest values. The DAP and MAP were comparable regarding their favorable effect on rice growth occupying the second position after ammonium sulphate. The ammonium sulphate had high yield component giving high grain yield followed by DAP and then MAP. Generally, urea or ammonium nitrate as well as any sources contains nitrate is not efficient to apply it for rice under the same saline sodic soil conditions.

Nineteen inbred lines of white maize divered from S5 generation at Sakha Agricultural Research Station were crossed with two inbred lines as testers in 2014 summer season. The 38 topcrosses were evaluated at Sakha and Mallawy Research Stations during summer season 2015 for eight studied traits, namely days to 50% silking, plant and ear heights, grain yield (ton/ha) adjusted on 15.5% grain moisture content, ear length (cm), ear diameter (cm), number of rows per ear and number of kernels per row. Mean squares due to lines , testers and line×tester were highly significant for most traits. While the interaction between lines, testers and locations were not significant for most traits. One topcross Sk5002/9×Sk13 (14.5 ton/ha) outyielded the check SC128 (13.2 ton/ha), also 13 topcrosses outyielded significantly the single cross SC10. These crosses could be used in the maize breeding program in the future. Highly significant and desirable GCA effects were exhibited in Sk5001/2, Sk5002/9, Sk5002/10, Sk5002/11 and Sk5003/15 inbred lines for grain yield. Generally these inbred lines could be used in future stage of evaluation in the maize breeding program.

Two experiments were carried out during 2014/2015 and 2015/2016 seasons, at the Experimental Farm, Faculty of Agriculture, Suez Canal University, Ismailia, Egypt, to study the effect of nitrogen forms (ammonium nitrate and urea) and sulfur treatments (0, 5, 10 and 15 mM) from two sources (potassium sulphate and calcium sulphate) on garlic yield, chlorophyll, carbohydrates, phenols, nitrate and elements content. Results revealed that ammonium nitrate-fertilized plants had the highest nitrate content in the absence of sulfur treatments. However, plant growth, yield, chlorophyll, phenols, NPK, Ca and S reached the maximum values and nitrate content decreased when plants were sprayed with potassium sulphate at 10 mM. Potassium sulphate was more favorable than calcium sulphate for improving the plant growth, yield and other bulb quality such as phenols and S content. Urea-fertilized plants showed less bulb yield and nitrate content than ammonium nitrate-fertilized plants, but higher than un-fertilized plants. Chlorophyll, nitrogen, phenols and S content were lower and the carbohydrates content was higher in plants grown with un-fertilized than in well fertilized with nitrogen. The results showed that N and S nutrition during the growth and bulb production are strongly coupled. Their interactions are synergistic at suitable form of nitrogen (ammonium nitrate) as well as at optimum rate of potassium sulphate (10 mM). However, excessive level of potassium sulphate (15 mM) seems to be antagonistic. Together, the results indicate that S spraying is required to improve N-use efficiency and thus increasing the bulb yield with high minerals nutrient such S and N content which are very important for S-containing bioactive compounds in garlic.

Two storage experiments were carried out at El-Mansoura Horticultural Research Station, Dakahalia Governorate, Egypt, during four months of storage in summer seasons of 2013 and 2014 for studying the effect of seven treatments, i.e,. natural essential oils and selecron on storability and quality of potato tubers and reduction percentages in the infestations potato tubers moth (PTM) under Nawwala condition. These treatments such as ; clove oil, garlic oil, lemonion oil, eucalyptus oil, peppermint oil, basil oil, mixture of these oils and selecron. The obtained results revealed that all storage treatments expect, selecron and control gave different significantly in all studied characters. Using peppermint and clove oils recorded the lowest significant values of sprouting percentage, sprout weight, sprout length and weight of loss percentage in both seasons. The highest values of dry matter %, starch% and vitamin C were recorded with peppermint oil, but the lowest sugar percentage was obtained by using the same treatment during two seasons. Results indicated that the effects of essential oils and selecron under storage in Nawwala conditions on Phthorimaea operculla (Zell.) (PTM), after four months of storage, the tubers infestation in control were (48- 48.67%), while the mean reduction percentages of infestation ranged between (94.10- 98.86% and 93.23- 96.84) during two seasons of 2013/2014 respectively. Peppermint oil, eucalyptus oil, clove oil and mixture oils gave highest mean reduction percentages of infestation such as selecron. Generally, the obtained data indicated that all used oils offered the highest protection. Also, the results in laboratory showed that the effects of oil treatments on larvae PTM recorded significantly variation according to the type of oil and time of exposure which showed fatal action on the larvae of PTM. The efficacy of Peppermint oil, Eucalyptus oil, clover oil and Mixer oils were the best. The percent of mortality ranged between (76.14 and 100%) compared with selecron. Also, all oils were used effected inhibitor action on adults. The inhibition of egg laying and reduction percentages ranged between were (47.54 %and 95.02 %) of peppermint oil and galaric oils, respectively. This study recommends that it can be sprayed peppermint oil concentration at (2 cm 3 / L / ton) three times during the storage of potato tubers in Nawwala for (4 months) in order to reduce the proportion of sprouting and weight loss and rotting and get a higher percentage of dry matter, starch and less injuries Pferashh (PTM) in tubers. Finally, it could be recommended with peppermint oil, eucalyptus oil, clove oil and mixer oils were the best during storage to obtain the best characters storage and quality. These natural treatments are very safe and potent in improving storability and greatly decreasing PTM insect infection during storage conditions in Nawwala on potato tubers.

Suitable broccoli nutrition has a great impact on curd yield and quality. There for two field experiments were carried out during the two successive winter seasons of 2013-2014 and 2014-2015 at the experimental station, Faculty of Agriculture, MansouraUniversity to study the effect of nitrogen and boron fertilization on yield and quality of broccoli. The experiment layout was split plot in a completely randomized block design arranged in three replications. Nitrogen fertilizer rates (i.e.; 60, 70, 80 and 90 kg per fed.) were present in the main plots, while boron treatments (0.4, 0.8 and 1.2 kg per fed.) were assigned in the sub plots. The results showed that the interaction between N and B was significant on vegetative growth parameters (i.e.; plant height, leaves area, leaves fresh weight, leaves dry matter percent), leaves mineral content such as N, P and K. Curds yield and its physical quality parameters (i.e.; curd weight, curd diameter and curd dry matter percent), curds chemical quality parameters (i.e.; Vit. C, T.S.S., chlorophyll a, chlorophyll b, carotenoids, N, P, K and nitrate content). On contrast the leaves number, curd length (cm) and curd compactness index were not significantly affected. The combination between nitrogen at 70 kg and boron at 0.8 kg per fed. was the most effective treatment, Since it recorded the highest values of all measured parameters and the lowest nitrate content in both seasons. On contrary, the highest level of nitrogen 80 or 90 kg with high rate of boron 1.2 kg per fed. gave the lowest values of curd yield and quality parameters.

A two years' field trial was conducted at Gemmaiza Agricultural Research Station, during 2013/14 and 2014/15 seasons to study the effect of plant residues; rice straw, corn stover and fahal berseem as a cash crop on wheat production and soil properties. The experimental design was strip-plot design in three replications. Where rice and maize were occupied the vertical stripplots, while the plant residues were occupied the horizontalstrip plots. Rice straw treatments were: untreated soil with rice straw, treated soil with chopped rice straw output of 33 % from the previous crop and fahal berseem one cut residues incorporated in soil followed by wheat. The same treatments were repeated with corn residues. Results showed that available N, P and K in soil were increased resulting from the decomposition of rice straw and corn stover. This improved soil fertility which is reflected in increasing the productivity of wheat crop compared with the other treatments. Also, application of different treatments significantly influenced the yield and its attributes of wheat crop in both seasons. The highest values of cereal units, economic evaluation and net return were resulted from the crop sequence corn followed by fahal berseem one cut followed by wheat, compared to other treatments in both seasons, respectively.

Most of farmers in Kafr El-Sheikh area accustomed to grow pea as cash vegetable crop in the short period lied between summer and winter crops before growing summer season and they need to control weeds in such crop. Thus, this investigation was carried to study the response of pea plant Master B, variety and their associated weed in two field experiments were during 2013/2014 and 2014/2015 winter seasons at Sakha Horticultural Research Station Farm, Kafr El-Sheikh Governorate. A split plot in a randomized complete blocks design with four replications was used. Where the response of pea plants, two inoculated with the rhizobium bacteria and someweed control treatments.The main plots included rhizobium bacteria inoculation and uninoculated control, the sub plots included eight weed control treatments i.e pendimethalin at 1.7L/fed, pendimethalin at 1.25L/fed plus hand hoeing once, pendimethalin at 1.0 L/fed plus hand hoeing twice; butralin at 2.5L/fed; butralin at 2.00 L/fed plus hand hoeing once; butralin at 1.0 L/fed plus hand hoeing twice, hand hoeing twice and untreaded control. The main findings in this study were as follow: Rhizobial inoculation with pea seeds caused significant increases in both seasons in number of nodules plant–1, fresh, dry weight of nodules plant–1 and increased yield ton/fed by (58.1, 37.5, 37.5 and 16.7%), in 2013/2014 season and (57.9, 35.3, 38.5 and 22.7%), in 2014/2015 season, respectively.This was accompanied improving pea plant growth characteristics caused indirection suppressed on the dry weight of weeds, than non-inoculation seeds treatment condition and increasing competitiveness of pea plant. There is no approves inhibition effects on bacterial nodules formation the use herbicides on number of nodules plant–1, fresh and dry weight of nodules plant–1 except with pendimethalin at 1.7L/fed, which decreased the fresh and dry weight of nodules plant–1 by (46.7 and 37.5%), in 2013/14 season and, (47.1 and 41.7%), in 2014/15 season. All weed control treatments reduced dry weight of broadleaf, grassy and total weeds due to weed species susceptibility to herbicidal the use herbicidal as compared with untreated control. The effective weed control treatments could be arranged in a descending order according to their depressing the dry weight of total weeds increasing peas yield and its components as follows: butralin at 2.00 L/fed plus hand hoeing once and increased pea yield by (72.7 and 76.9%), in 2013/14 season and (70.4 and 75.0%), in 2014/15 season than untreated check.The effect of interaction between with rhizobial inoculation and weed control treatments on bacterial nodules were statistically significant in both seasons. Most herbicidal treatments under uninoculation condition inhibited to somewhat number of nodules/plant, fresh and dry weight of nodules/plant except with some treatments which were similar its untreated check and rhizobial inoculation with herbicidal treatments can be help bacterial nodules recovery from the sides effects of herbicide. Meanwhile, the previous interaction gave 95% weed control accompanied increase in pea yield ton/fed with applying rhizobial and adding, butralin at 2L/fed plus hand hoeing once, where improved of weed control and enhancing pea growth with rhizobial inoculation other interaction were discussed as show in manuscript of paper. The dry weight of total weeds biomass was correlated indicating negative with pea yield indicating to the severity of weed competition on pea yield and its components which may be attributed directly to the improvement of weed control in one side and enhancing the grow of pea/plants by increasing effective bacterial nodules in fixing nitrogen in the other sides. Thus, we can recommend farmers to inoculate pea seeds with rhizobial inoculation and use the proper herbicidal treatments to control weeds in pea field as good alternative to mechanical hand hoeing.

In 2012, six maize inbred lines were crossed in all possible combinations without reciprocals by using a half diallel cross mating design to obtain 15 single crosses. 15 F1 single crosses were evaluated through 2013 season under 2 irrigation treatments, every 12 day (Normal irrigation) and every 18 days (stress), to assess the role of general and specific combining ability of inbreds in hybrid behavior under recommended irrigation and water stress conditions. Results showed that mean squares due to crosses, general (GCA) and specific (SCA) combining abilities were significant or highly significant for all studied traits under both non-stressed and water stressed conditions, except of SCA for plant height under both conditions, which was insignificant. This result indicated that both additive and non-additive gene effects are very important in the inheritance of these traits. The ratio of GCA/SCA were less than unity for anthesis date under both conditions, silking date under normal irrigation, ear leaf area at stress condition, ear length under both conditions, and ears yield per plant at stress condition, indicating that the non- additive genetic effects were more important and played the major role in the inheritance of these traits under these conditions. On the other hand, GCA/SCA ratios were more than unity for silking date under stress condition, ear leaf area at normal irrigation, plant height under both normal and stress conditions, and ears yield per plant at normal condition, indicating that the additive genetic effects were more important and played the major role in the inheritance of these traits under these conditions. The best general combiners were: P2(Rg5) and P6(B 73) under both conditions, and P4 (R39) under normal for earliness;P1(Inb. 209),P5(Sids7) under normal, and P2 (Rg5) under both conditions for ear leaf area; P5(sids7) under normal, and P6(B73) under both conditions for plant height(shortness);P1(Inb.209) and P3(sids34) under both conditions for ear length; and P1 (Inb.209) under normal, and P2 (Rg 5) under both conditions and P4 (R39) under stress for ears yield per plant. The best cross combinations were: eight crosses (No. 3, 4, 5, 6 , 9, 10, 12 and 13) under normal, and five crosses (No. 2, 3, 6, 9 and 13) under stress for earliness; two crosses No. 2 and No. 12 under normal, and three crosses No. 6, 13 and 15 under stress for ear leaf area; crosses No. 5 and 6 under normal and cross No.5 under water stress for plant height (shortness);four crosses i.e. No.4, 8,10and 12 under normal, and four crosses No. 2, 12,13 and 15 under stress for ear length; and three crosses i.e. No. 1, 12 and 13 under normal, and six crosses No. 2, 4, 6, 12, 13 and 15 under stress for ears yield per plant.

Two field experiments were carried out in clay loam soil at Experimental farm, Baramon, Dakahlia Governorate during the two winter seasons of 2010/11 and 2011/12 to investigate the effect of four sowing dates (15 Oct., 1 Nov., 15 Nov. and 1 Dec.) and three harvesting patterns (without cutting C0, one cutting C1 and two cuttings C2) as well as their interaction on yield and quality of spinach cv. Balady. The experiments were laid out in a split plot design with three replicates where sowing dates were the main factor and the number of cuttings was the secondary factor. The obtained results indicated that sowing date at mid October followed by first of November promoted vegetative growth characters, which showed a significant increase in plant height, number of leaves/plant and average leaf area. In addition, early sowing at mid October and first of November produced the greatest fresh foliage weight/plant, fresh yield and total fresh yield. Moreover, early sowing dates increased dry matter content in spinach leaves but showed the least values for total chlorophyll content. Harvesting spinach plants without cutting led to an increase in plant height and average leaf area, whereas the second cutting exhibited the largest number of leaves/plant. Harvesting plants without cutting showed the largest means of plant height, average leaf area, foliage fresh foliage weight/plant and fresh yield, while total fresh yield was increased by cutting spinach plants twice. The interaction between sowing dates and number of cuttings showed significant differences for all studied characters in both seasons of the study. Generally, it could be concluded that the suitable treatment to maximize spinach yield was sowing spinach at mid October or first of November and cut plants twice. Otherwise, delaying sowing date causes a reduction in vegetative growth and consequently total yield production

The aim of this investigation was to study combining ability, gene action and heterobeltiosis for some traits and determination of aflatoxin contamination in peanut. A diallel cross, without reciprocals, among five parents was done in 2013. Data revealed that the mean squares of genotypes, parents and crosses were significant for all studied traits in both of F1 and F2 generations. The analysis of variance for combining ability showed that mean squares due to general (GCA) and specific (SCA) combining ability were generally significant for all studied traits reflecting the importance of both additive and non- additive gene effects in the inheritance of these traits. The lines A1and 623 were good combiners for 100-pod weight, shelling percentage and pod yield feddan-1 in the two seasons (one ardab=75kg and one feddan=4200m2). Genotypes 10A and 2A were good combiners for number of pods plant-1, pod weight plant-1, number of seeds plant-1 and seed weight plant-1 in the second season. Regression line intersects the Wr axis below the origin in shelling percentage in F1 and F2 generations and pod yield feddan-1 in F2 generation, reflecting over- dominance. On the other hand, pod yield feddan-1 was controlled by partial dominance. Among these gene action partial dominance could easily be exploited through conventional breeding. Positive or negative heterosis over the better parent, i.e. heterobeltiosis was detected for all studied traits. Determination of aflatoxin contamination under normal storage conditions showed that the two crosses (P3X P4 and P3X P5) had total aflatoxins of 10.6, 20.1ppb, respectively. Meanwhile, total aflatoxins were not detected in parents and other F2 crosses.

This investigation was carried out at the experimental farm of EL-Serw Agriculture Research Station and Seed Technology Research Unit Mansoura, Agricultural Research Center from 2012 to 2015 year to study the effect of cuts number (without cut (control), one cut and two cuts) and harvesting dates (25, 32, 39, and 46 days after 50% flowering) on fresh and seed yield, of Sudan grass as well as, seed quality after different storage periods. The main results can summarized as follows: Left Sudan grass plants without cut (control) and harvesting after 39 day from 50% flowering gave the highest values of plant height, straw fresh and dry weight kg/ plot, 1000-seed weight and seed yield / plot. Two cut treatments associated with the highest values of total fresh and dry forage yield/plot. Seed produced from the fourth harvest date without cutting gave the best values of seed germination percentage and seedling vigor traits followed by one cut then two cuts under different storage periods conditions. Increasing storage periods from six to 18 months led to the reduction in seed quality traits. So, sorghum Sudan grass plants one- cut before seed production could be considered the most suitable treatment to produce high yield and seed quality.

Agron. Dept., Fac. Agric., Zagazig University, Egypt.
In order to study the response of two yellow maize hybrids i.e. SC 173 and TWC 352 to three irrigation intervals i.e. 12, 16 and 20 days and four nitrogen fertilizer levels i.e. 0, 45, 90 and 135 kg N/fad. The present investigation was carried out during two successive seasons of summer 2011 and 2012 at the Agriculture Research Station, Faculty of Agric., ZagazigUniv., Ghazala Location, Sharkia Governorate, Egypt. The combined analysis indicated that all growth characters as well as grain yield and its attributes except number of rows/ear and shelling percentage were significantly decreased when irrigation interval was prolonged from 12 or 16 days to 20 days. It was found that SC 173 surpassed TWC 352 in all growth characters, grain yield and its attributes except, number of ears/ plant, number of rows/ear and shelling percentage. On the other direction, TWC 352 surpassed SC 173 in ear diameter. Respecting to the influence of nitrogen fertilizer levels, the results indicated that ear length, ear diameter, 100-kernel weight, kernel weight/ear and grain yield/fad were significantly increased with each increase in nitrogen fertilizer level up to 135 kg N/fad. Whereas, plant height, chlorophyll content and number of kernels/row were significantly increased by raising nitrogen fertilizer level up to 90 kg N/fad while, number of ears/plant was responded only up to application of 45 kg N/fad. The results of interaction between the studied factors recorded significant increase in kernel weight/ear and grain yield/fad due to increasing nitrogen fertilizer level up to 135 kg N/fad under irrigation intervals of 12 or 16 days. In addition, SC 173 presented good response for N fertilizer up to 135 kg than TWC 352 in 100-kernel weight, kernel weight/ear and grain yield/fad. It could be recommended that irrigation of SC 173 hybrid at 16 days intervals with adding 135 kg N/fad maximized grain yield per unit area under clay soil condition of Sharkia Governorate, Egypt.

This study was carried out at El- Baramoon Research Farm, Mansoura Horticulture Research Station, HRI, ARC, Egypt, during the two winter growing seasons of 2012/2013 and 2013/2014, to determine the optimum time of harvest coriander fruits for maximum viable fruit yield and oil percentage. Coriander fruits were harvested at seven different maturity stages. In this investigation, it has been found that the maximum yield and quality of coriander fruits in terms of fruit yield, thousand fruit weight (seed index) and germination percentage were reached its maximum at the third stage (the secondary umbels colour was changed). Moreover, essential oil percentage was higher in the early harvesting stages and was high at the first maturity stage (the primary umbel was at the beginning of waxy stage). In addition, essential oil yield / plant with high linalool content reached their maximum when fruits harvested at the third stage. Generally, it could be recommended that to obtain the maximum fruit yield and quality as well as high essential oil yield with high linalool content, coriander fruits should be harvested at the third maturity stage of fruit development.

Coriander (Coriandrum sativum L.), a member of the Apiaceae family, is among most widely used medicinal plant, possessing nutritional as well as medicinal properties. Thus, the present study aimed to investigate the effect of foliar application of chitosan at 20, 40, 60 and 80 ppm and salicylic acid at 15, 30, 45 and 60 ppm on improving coriander production for fruits and essential oil. The study was conducted at El- Baramoon Research Farm, Mansoura Horticulture Research Station, HRI, ARC, Egypt, during the two growing winter seasons of 2013/2014 and 2014/2015. It is clear that foliar application of either chitosan or salicylic acid at all used concentrations significantly promoted the vegetative growth characters in terms of plant height, number of branches per plant and plant fresh and dry weights. Moreover, fruit yield and its components in terms of number of umbels per plant and fruit yield per plant were also significantly higher than control treatment. Germination percentage, seed index and essential oil percentage and content were positively affected by foliar application of chitosan or salicylic acid with the superiority of chitosan. The greatest increase in the previously mentioned parameters was measured in plants (vegetative growth and yield components) sprayed with chitosan at 80 ppm followed by chitosan at 60 ppm and salicylic acid at 45 ppm. For obtaining high fruit yield and its quality as well as essential oil percentage and content of coriander plants, it could be recommended to spray plants twice with chitosan at 80 ppm.

During 2013/ 2014 and 2014/2015 seasons, Valencia orange trees received three sprays; at growth start, directly after fruit setting and after one month with three plant oils; clove, ginger and turmeric each at 0.025 ,0.05 and 0.1% besides the control treatment. Treating the trees three times with oil of clove, ginger or turmeric each at 0.025 to 0.1% effectively stimulated yield, fruit quality, leaf area and leaf content of pigments, N, P, K and Mg comparing with the control treatment. The promotion was related to the increase in concentrations of these plant oils. Negligible stimulation on all the previous parameters was revealed among the higher two concentrations namely 0.05 and 0.1% . Using oils of clove, ginger and turmeric was effective in an ascending order in this connection. It could be concluded that spraying Valencia orange trees grown under Assiut region conditions with turmeric oil (0.05%) three times resulted in the highest yield and the best fruit quality.

The present study was conducted during two successive experimental seasons (2014 and 2015) on Fuerte avocado (Persea americana Mill.) at avocado orchard belonging to Horticulture Research Station at El-Kanater El-Khayira, Kalyubeia Governorate, Egypt. The trees were about 18-years old when this study started, planted at square system (7 meters apart), the soil orchard was clay loamy. The trees received the regular cultural treatments according the recommendation of Ministry of Agriculture and irrigated through farrow (surface) irrigation system. The objective of this study was to evaluate the effect of (milagrow), nutrient compounds (potassium 10 %, phosphorus 20 %, boron 3 % and brassinolide 0.2 %), on fruit set and fruit retention (%), number of fruit/tree and yield as well as fruit quality of avocado tree cv. Fuerte. This study evaluated applications of milagrow 0 (control), 2.5, 5.0 and 7.5 g/L at different growth stages; a) swollen bud stage, b) Full bloom c) beginning of fruit set during 2014-2015. Results cleared that foliar applications of milagrow to avocado tree cv. Fuerte increased all fruit parameters. Regard to fruit set and fruit retention % trees which treated with 7.5 g/100 L produced the highest value of each. Regarding the yield, highest yield was obtained from treated with 5 g/100 L in comparison with other treatments followed by “7.5 g/100 L" and “2.5 g/100 L" while it was the lowest with "control". As well as trees which treated with 7.5g/100 L and 5 g/100 L produced the highest number of fruits /tree while the lowest number of fruits/tree was recorded for untreated trees. Concerning physical properties, data proved the highest value of fruits in their weight, dimensions and flesh/fruit weight % with treatment 5 g/L meanwhile the lowest fruits were on the opposite at treatment 2.5g/L and untreated trees. Regarding fat content, the differences between treatments did not reach the level of significance. Results indicated that if milagrow is used at swollen bud stage as foliar application, increased both fruit yield and improved fruit quality. Additionally, milagrow resulted in yield increment.

Two field trails were carried out at El-Mattana Agricultural Research Station (latitude of 25.17o N and longitude of 32.33o E), Luxor Governorate, Upper Egypt during 2013/2014 (virgin cane) and 2014/2015 (first ratoon crop,) to find out the optimum harvesting age for some sugarcane varieties. Treatments consisted of a factorial combination of three promising sugarcane varieties (G.98-28, G. 99-160 and G.2003-49) and five harvesting age (10, 11, 12, 13 and 14-months) were arranged in factorial experiment conducted in randomized Complete Block Design with three replications. The results showed that all of the studied traits were significantly influenced by delaying the harvest age from 10 to 14-month age. Also, the results showed that the three promising sugarcane varieties significantly differed in stalk cane length, diameter, as well as Brix, sucrose purity, sugar recovery percentages, cane and sugar yields (Ton/fed.). Generally, promising sugarcane variety G.2003-49 was superior over the other two varieties i.e. G.98-28 and G. 99-160 in cane and sugar yields (Ton/fed.).

The present study was carried out during the three growing seasons 2011, 2012 and 2013 at Experimental Farm, Fac. of Agric., ZagazigUniversity. A half diallel crosses among eight yellow maize inbred lines i.e. Z12 (P1), Z15 (P2), Z167 (P3), Z147 (P4), Z40 (P5), Z56 (P6), Z58 (P7) and Z103 (P8) were evaluated under well-watered and water stress environments. The data were recorded for the days to 50% silking, anthesis silking interval, plant height, ear leaf area, leaf water content, ear diameter, ear length, number of rows per ear, number of kernels per row, 100-kernel weight, grain yield (ard./fad.). The combined analyses of variance for combining ability revealed that mean squares for general combining ability (GCA) and specific combining ability (SCA) were highly significant across two environments for all studied characters, indicating the prevalence of additive and non-additive gene action in the gene expression of these characters, but the ratio of GCA/SCA variances were more than unity for days to 50% silking, plant height and number of rows per ear, indicating the major role of additive gene effects in controlling the genetic mechanism of these characters over water environments. In contrast, the ratio of variance GCA to variance SCA was blow one for anthesis silking interval, ear leaf area, leaf relative water content, ear diameter, ear length, number of rows per ear, number of kernels per row, 100-kernel weight and grain yield. This emphasized that, non-additive gene action was the prevailed type in controlling these characters. Narrow sense heritability estimates were high (> 50%) for days to 50% silking, plant height, ear diameter and number of rows per ear, moderate for ear leaf area (41.68%) and ear length (45.55%), and low (< 30%) for anthesis silking interval, leaf relative water content, number of kernels / row, 100-kernel weight and grain yield over two environments. Reduction % due to water stress valued, (32.83%) for grain yield (ard./fad.), (15.60%) for plant height, (14.99%) for ear length, (13.99%) for ear leaf area, (12.17%) for 100-kernel weight, (10.63%) for number of kernels/row, (6.98%) for ear diameter, (6.64%) for leaf relative water content and (4.22%) for number of rows/ear. The best parental combiners were Z167(P3) and Z147(P4) for grain yield and most its components under optimum irrigation and water deficit. The crosses, (P3 x P6), (P2 x P3), (P4 x P7), (P4 x P8) and (P6 x P8) had the most desirable and highest values for mean performance, SCA effects, heterosis effects, droght toleranc index (DI) and stress tolerance index (STI) for grain yield, anthesis silking interval and other performance traits. The yellow maize crosses (P2 x P3) and (P4 x P8) were significantly outyieled the check varieties. Grain yield had positive and significant genotypic and phenotypic correlations with ear leaf area (0.443** and 0.355**), leaf relative water content (0.488** and 0.307**), ear diameter (0.691** and 0.546**), ear length (0.783** and 0.647**), number of rows per ear (0.291* and 0.237), number of kernels per row (0.486** and 0.451**), 100-kernels weight (0.659** and 0.543**) and drought susceptibility index (0.484** and 0.388**, respectively), but had negative correlations with days to 50% silking (-0.034 and 0.004) and anthesis silking interval (-0.572** and -0.491**, respectively). The results showed that ear length exhibited the largest direct effect on grain yield (0.340) followed by drought susceptibility index (0.251), leaf relative water content (0.231), ear leaf area (0.182), number of kernels per row (0.171), ear diameter (0.135) and number of rows per ear (0.104).

In order to monitor heterosis, inheritance and interrelationship among morpho-physiological and yield characters in sunflower, half diallel crosses among seven genetically divergent inbred lines were evaluated under adequate water supply, moderate and severe stress. Drought sensitivity index indicated that the parental sunflower genotypes L38 and L990 and the F1 crosses L38 x L990and L350 x L460 were more tolerant to water stress, whereas L11 and L235 and the F1 cross L11 x L990 classified as sensitive one. Cross combination L38 x L350 scored desired and significant heterosis for leaf chlorophyll content at moderate stress; transpiration rate at severe stress; achene yield/plant and achene oil content at adequate water supply and moderate stress. Additive gene action had a great role in controlling transpiration rate, plant height and achene oil content, while dominance was important in controlling achene yield/plant under the three levels of water regimes. The environmental variance had significant effect on gene expression of physiological and yield characters in most cases. Narrow sense heritability was high (>50%) for transpiration rate and low (< 30%) for achene yield/plant under the three levels of water regimes. Significant positive correlations were registered between achene yield/plant and each of leaf water content, transpiration rate, plant height, head diameter and 100-achene weight across three environments. The maximum direct effect on achene yield/plant was accounted for transpiration rate and plant height with values of 12.941% and 12.219%, respectively. The highest indirect effects on achene yield/plant variation were observed for transpiration rate via plant height followed by transpiration rate via 100-achene weight; leaf water content via 100-achene weight with values of 8.442%, 5.530% and 4.579%, respectively across three environments.

Six bread wheat parents and their diallel F1 (in 2012/13 season) and F2's (in 2013/14 season) hybrids were evaluated to estimate combining ability for earliness, agronomic and leaf and stem rusts resistance traits. The parents were Gemmeiza 9, Sids 12, Misr 1, Misr 2, Sids 1 and Cham 4. The studied characters were: number of days to heading and maturity, grain filling period and rate, plant height, number of spikes plant-1, number of kernels spike-1, 100 kernel weight, grain yield plant-1, leaf and stem rusts resistance in the F1 hybrids; and plant height, number of spikes plant-1, number of kernels spike-1, 100 kernel weight, grain yield plant-1, leaf and stem rusts resistance in the F2 hybrids. The variances due to genotypes, parents, crosses and parents vs crosses were significant for most characters, reflecting sufficient genetic variability. According to the mean squares due to the general and specific combining ability, the additive and nonadditive gene effects were involved in the expression of most studied traits and the additive genetic effects were more important. Heterotic effects were revealed for leaf rust and stem rust resistance in F2. Misr 1 and Sids 1 were the highest parents in mean performance and best good combiners for grain yield plant-1 in the two seasons. The highest grain yield plant-1 was detected in Misr 2 x Sids 1 F1 cross and in Misr 2 x Sids 1, Misr 1 x Sids 1 and Gemmeiza 9 x Sids 1 F2 crosses. The best F1 and F2 cross for grain yield plant-1, leaf rust and stem rusts resistance was Misr 2 x Sids 1. Except Sids 1, the parents were resistant or moderately resistant to leaf rust, while Gemmeiza 9, Sids 12 and Sids 1 were the most resistant parents to stem rust resistance in the two seasons. The most F1 crosses were resistant to leaf rust and sensitive or moderately sensitive for stem rust resistance.
