In this investigation three inbred lines which were desired from Balady squash population by selection and their 6 F1 hybrids including reciprocal were used as genetic materials. The inbred lines and their F1 hybrids included reciprocal hybrids were evaluated for some economic traits; vegetative growth, flowering and earliness as days to first female flower anthesis, fruit, as well as yield and its component traits in field trial during 2014 summer season. The result of mean values showed that no parental line was superior for all studied traits. Meanwhile, the parent P3 exhibited the best values for most studied traits. As well as, the obtained results showed that the highest values recorded in the F1 hybrids compare with their parents (inbred lines) were; i.e., P3xP2 for earliness and sex ratio, P3xP2 for fruit number per plant, P1xP3 for total yield per plant. As well as, P1xP2 for total soluble solid and dry weight of fruits, P2xP3 and P3xP1 for ascorbic acid content. These crosses could be used as commercial cultivars which may compete with imported hybrids. Moreover, their parents (stable inbred lines) which exhibited best combinations for previous traits could be used in breeding program according to their objectives.

Field and laboratory experiments were conducted at Gemmeiza Agric. Res. Station and Mansoura Seed Tech. Unit, Agricultural Research Center during 2011/2012 and 2012/2013 seasons to evaluate promising ten faba bean genotypes with three commercial cultivars; Giza 843, Misr 1 and Improved Giza 3. The main results cleared, Genotype 9 was the earliest in flowering and maturity dates. Genotypes 1,3,5 and 8 surpassed in number of pods/plant and number of seeds/plant. Genotypes 4,1,8 and 3 surpassed the other genotypes in 100-seed weight, seed weight/plant, germination percentage, seedlings vigor traits, meanwhile, recorded the lowest values for mean germination time and electrical conductivity compared with the three local commercial cultivars. There were positively and highly significant correlations between seed weight/plant and each of number of seed/plant, germination percentage, seedling length, seedling vigor index and germination rate, while, negatively and highly significant correlations between seed weight/plant both of electrical conductivity and mean germination time. Generally, under North Egypt conditions, we can sowing promising faba bean genotypes 4,1,8 and 3 (G.461xG.402, G.461x Nubaria 1H.8xG.461 and G.716xG.402) to obtain high yield/plant and good seed quality as well as using them in breeding program.

Six diverse lines of tomato were crossed with six testers in line x tester mating fashion to study heterosis relative to mid parents, better parent and check hybrid and combining ability for some plant and fruit characteristics. The experiment work was conducted at the Exp. Farm, Fac. of Envir. Agric. Sci., El Arish, Suez Canal Univ., Egypt, during the period from 2012 to 2014. For heterotic effect, heterosis over mid-parents, better parent and check hybrid were detected in many traits, viz.; plant height, number of branches, total yield/plant and total fruit number. On the other hand, no heterosis was detected for fruit firmness based on check hybrid. The magnitude of SCA variance was greater than GCA variance suggesting the predominance of non-additive gene action for all studied traits. Among the lines, the good general combiner was AVTO9802 for total yield/plant and fruit firmness and AVTO1008 for average fruit weight. Among six testers, Super Marmand exhibited the highest significant GCA effects for plant height and number of branches/plant, FM–9 was the best for total yield/plant and Castle Rock for average fruit weight and fruit firmness. The estimates of specific combining ability effects (SCA) show superior specific combinations, AVTO1003 x Super Marmand for plant height, AVTO1002 x Peto 86 for number of branches, AVTO1003 x Rio Grande for total fruit number, AVTO0101 x Super Strain B for average fruit weight, AVTO1002 x Super Marmand for TSS%, AVTO0101 x Castle Rock for ascorbic acid content and AVTO1002 x Rio Grande for fruit firmness. Therefore, from general and specific combining ability and some genetic parameters suggested the importance of heterosis breeding for effective utilization of non-additive genetic variances, which had predominant role for the improvement of for some plant and fruit characteristics traits in tomato crop.

This investigation was conducted in (2012 and 2013) seasons on 14 years old Valencia and Washington navel orange trees(Citrus sinensis L.) on sour orange (Citrus aurantium L.) rootstocks and spaced at 5 × 5 m in a private orchard. Its aim to study the effect of foliar spraying with seaweed extract at 200, 250 and 300 cm /100 liter in 2 stages (before flowering and after initial fruit set).
Foliar spraying with seaweeds extract on Valencia and Washington navel orange trees were significantly increased almost studied characters. The tested data of fruit set, yield, fruit quality and leaf chemical composition were max - in Washington navel orange trees compared to Valencia orange trees, where seaweeds extract gave maximized in Washington navel orange trees than in Valencia orange trees.
Trees sprayed with it gained that the longest shoot length as compared with untreated control trees. The largest leaf surface area/ area was recorded for trees that sprayed with seaweeds extract in both study seasons. Spraying seaweeds extract (300 / 100 liter which added before flowering) significantly affected initial fruit set % in both study seasons. Treat. (7) sprayed trees gained the highest initial fruit set percentage, followed by Treat. (4) compared with control trees.
Trees sprayed with seaweeds extract (300 cm / 100 liter) after initial fruit set led to reduce June drop % in both seasons than untreated ones. Tree yield (fruits number and kg/ tree) were significantly increased as compared to the control treatment.
Data revealed that fruit weight, fruit L/D ratio, T.S.S, T.S.S /acid ratio and vitamin C were significantly increased by foliar spraying with seaweeds extract associated with increasing concentration, where the highest values were obtained from (Treat. 7) followed by (Treat. 4) in both seasons compared to control. In contract, total acidity was reduced with all treatments compared to control in both seasons.
In addition, Treat. (7) gave significant increment of leaf (mineral content) as N, P, K, Ca, Mg, Fe, Zn, and Mn followed by Treat. (4) in both seasons compared to control.
Also, data indicated that leaf content of chlorophyll (a & b) and carotenoids were increased when applied 300 cm seaweeds extract/ 100 liter after initial fruit set fallowed by the same concentration before flowering in both seasons compared to the control trees.
Generally, it could be concluded that applying seaweeds extract to Valencia and Washington navel orange trees at 200, 250 and 300 cm /100 liter in 2 stages/ season (before flowering and after initial fruit set) enhanced shoot length and leaf surface area and increased initial fruit set %, increased yield/ tree, improved fruit quality, increased leaf mineral content and decreased June drop comparing with control treatment. While 300 cm seaweeds extract/ 100 liter after initial fruit set gave the best net profit.

Two field experiments were conducted during 2013 and 2014 growing seasons at Nubaria Region, Alexandria Governorate, Egypt in order to study the integrated effect of mineral nitrogen and biofertilizer (85 kg N/fed as recommended dose (control), 65 kg N/fed + 600 g Cerealin as biofertilizer and 45 kg N/fed + 600 g Cerealin) on three sweet sorghum varieties i.e., Sorgo, Brandes and Planter.
Results showed that Planter variety recorded the highest values of morphological characters i.e. stalk height, stalk diameter, leaf area, stripped, and juice yields as well as chlorophyll a and b concentrations compared with Sorgo and Brandes in both seasons. On the other hand, in both seasons syrup yield was significantly increased in Brands variety compared with other two varieties. In both seasons Planter variety gave the highest values of physiological characters i.e., sucrose%, pH value, total soluble solids%, purity% and extracted juice%, while, Sorgo variety recorded the highest value in reducing sugar.
The treatment of 65 kg N/fed + 600 g Cerealin gave the greatest concentrations of chlorophyll a and b in both seasons also gave the greatest values of stalk height, diameter and leaf area in the first season only, while, stripped stalks and juice yields recorded the highest values in both seasons. In the first season there was no significant difference in juice yield at the rate of 85 kg N/fed compared with 65 kg N/fed 600 g Cerealin, while, in the second season both treatments did not significantly differed in stripped stalks yield. Nitrogete fertilizer at rate of 65 kg N/fed + 600 g Cerealin gave the highest values of sucrose%, purity% and juice extraction% in both seasons. The interactions between Planter variety and 65 kg N/fed + 600 g Cerealin gave the greatest values in stripped stalks, juice and syrup yields followed by Brandes and Sorgo in both seasons.

Field experiments were conducted at the experimental Farm of the Faculty of Agriculture, Kafrelsheikh University during 2013/2014 and 2014/2015 seasons to study the effect of Azotobacter chrocooccum and Pseudomonas sp. on coriander (Coriandrum sativum, L.) and dill (Anethum graveolens, L.) plants. Indole-3-acetic acid in the supernatant of a culture A. chrocooccum and Pseudomonas sp. was detected. It was shown that Indole-3-acetic acid was induced by the presence of tryptophan. The highest concentration of Indole-3-acetic acid was produced byboth strainsat the end of the logarithmic phase.
The bacterial strains were applied at the time of sowing as seed treatment. Data showed that A. chrocooccum surpassed Pseudomonas sp. in most vegetative growth and flowering characters (plant height, number of leaves/ plant, herb fresh and dry weights/ plant and umbels and umbellts number/plant), while Pseudomonas sp. gave the highest weight of 100 fruits, fruit yield per plant and per Feddan for both plants, respectively. The highest total chlorophyll contents were obtained when coriander and dill were treated with Pseudomonas sp. and A. chrocooccum, respectively. Pseudomonas sp. gave the best results for total carbohydrates, vitamin C, fresh herb and dry fruit oil % and fruits oil yield/ plant compared to A. chrocooccum or control treatments.
Coriander fruit treatments with A. chrocooccum and Pseudomonas sp. increased anatomical parameters such as xylem vessel diameter, thickness of phloem tissue and vascular bundle as well as vascular bundle width comparing with the control treatment. The obtained results exhibited that, these bacterial strains could be used to increase coriander and dill productivity under field conditions.

This study was conducted under greenhouse conditions at Kaha Vegetable Research Farm (KVRF), Kalubia Governorate, Egypt through the period from 2011 to 2014. The objective of this work was to produce newly recombinant inbred lines (RILs) in cantaloupe using single seed decent (SSD) breeding method for seven successive generations. Four superior commercial hybrids of cantaloupe grown under Egyptian conditions viz., Primo, Mirella (galia type), Magenta and Kousto (charentais type) were utilized as a genetic materials in this work. The F8 seeds of twenty five cantaloupe RILs were selected and sown in the open field during early summer season of 2014 at KVRF to be characterized the RILs that they were had distinctness, uniformity and stability (DUS). Also, the value for cultivation and use (VCU) was used to determine the value of RILs as a cantaloupe genetic resources. In addition, to estimate the coefficient of variance (CV %) within and between the selected RILs, gain of selection and broad sense heritability were used. The results confirmed that the SSD breeding was effective and time saving method in cantaloupe. It was produced 25 selected RILs. The selected RILs had DUS, high fruit quality and yield. The CV % within selected RILs was very low except for RIL 176, but between it was very high which confirmed the DUS test results. This indicated that the selected RILs had very high homogeneity within it and large genetic distance between it. All studied traits had high heritability which ranged from 69.52 to 93.64 %, as well as, most of these traits gave high gain of selection. High heritability indicates less environmental influence in the observed variation. Also, high heritability coupled with high gain of selection for given traits which indicated that it is governed by additive gene action to be provides the most effective condition for selection. Finally, these selected RILs considered as a best resources to be used for cantaloupe improvement.

Barley is one of the major cereal crops cultivated in new reclaimed sandy soils. In order to decrease nitrogen pollution in barley fields, an trail was conducted to compensate barley inorganic nitrogen needs by organic manure under newly reclaimed sandy saline soils in North Nile Delta during 2011/2012 and 2012/2013 seasons at Experimental Station Farm, Faculty of Agriculture, Mansoura University, Egypt. A strip-plot design with four replicates was used. The vertical plots were occupied with three barley cultivars (Giza 129, Giza 130 and Giza 131). While, the horizontal-plots were devoted to five combination treatments of inorganic nitrogen and poultry manure i.e. 100% inorganic nitrogen, 75% inorganic nitrogen + 25 % poultry manure, 50% inorganic nitrogen + 50 % poultry manure, 25% inorganic nitrogen + 75 % poultry manure and 100 % poultry manure.
The results indicated that Giza 131cultivar surpassed other studied cultivars (Giza 129, Giza 130 cultivars) in all studied characters and recorded the maximum values in both seasons. Application of 75% inorganic nitrogen plus 25% poultry manure combination treatment recorded the highest values of all studied characters, followed by 100% inorganic nitrogen fertilizer, then 50% inorganic nitrogen and 25% poultry manure combination treatment, 25% inorganic nitrogen and 75% poultry manure combination treatment, and lastly 100% poultry manure only in both seasons.
On the basis of the results obtained, maximum grain and straw yields of barley resulted by fertilizing Giza 131 cultivar with 75% inorganic nitrogen beside 25% poultry manure under sandy saline soils in North Nile Delta.
