During 2019 and 2020 seasons Ewaise mango trees were subjected three times to foliar application of Egyptian clover and fenugreek seed sprout extract at 0.25 to 1.0%. The study focused on the impact of these treatments on growth, nutritional status of the trees, yield as well as physical and chemical characteristics of the fruits.Spraying Egyptian clover and fenugreek seed sprout extract at 0.25 to 1.0% was effective in enhancing growth traits, tree nutritional status, yield and fruit quality rather than non-application ones. The promotion was associated with increasing concentrations of extract used. Using fenugreek seed sprout extract was superior than using Egyptian clover seed sprout extract in this respect. No significant differences were seen due to increase in the concentration of used extracts. From the economic point of view, use the extracts of 0.5% are preferable.The best results concerning to growth, tree nutritional status, yield and fruit quality of Ewaise mango trees grown under Aswan region conditions were obtained due to use Egyptian clover or fenugreek seed sprout extracts at 0.5% three times.

Two field and laboratory experiments were conducted at Rice Research and Training Center (RRTC), Sakha. Egypt The first experimental was conducted with randomized complete block design with three replications to identify the mean performance of some rice varieties for morphological and yield characters, chemical, quality characters. The second experimental carried out at Rice Technology Training Center (RTTC) at Alexandria to study the effect of temperature, sample weight and their interaction on technological traits with split-split plot design with three replications during two seasons. The results showed that highly differences found for days to heading, plant height, number of panicles/plant, panicle weight, total grains/panicle and grain yield (t/fed) among the studied varieties. The Sakha 108 variety recorded the superior values for all the studied characters except days to heading. The Black rice variety recorded the lowest value for days to heading and plant height characters, while, recorded the desirable values for micro elements, zink, iron and protein, moreover, the short glutinous variety recorded the desirable values for fired characters. The Egyptian Yasmin was later one for days to heading, for the grain quality characters, moreover, recorded the desirable values for cooking characters as aromatic rice. Finally, it could be recommended these varieties used as adorners to improvement the grain quality characters in rice breeding program. Moreover, the denderogram analysis showed that the Egyptian yasmin as indica type was in one group, while, all japonica type was in second group, that confirmed with morphological, yield and grain quality characters.

Some organic supplements i.e., vermicompost which mixed with mushroom growth substrate (rice straw) at different levels 0.0, 2.5, 5, 10% beside compost teaat concentrate of (1:10) and Azolla plants extract at concentrate of 5% as organic spraying were used to enhance both of biological efficiency and productivity of Pleurotus columbines grown under uncontrolled conditions during the two seasons of 2019 and 2020. The results indicated the ability of vermicompost at high concentrate 10% to encourage mushroom fruiting phases, total yield/bag, biological efficiency, fruit chemical content and all fruit properties except the number of fruit per cluster which appears superior with rice straw sole without any additive (control treatment). On the other side, compost tea as organic spraying was the most influenced to obtain earlier primordial initiation and reduce the days required for both of fruit formation and fruit duration furthermore the high fruit content of protein, carbohydrate, P, K as well as fruit dry matter accumulation. While, Azolla plants extract resulted in the highestfruit characteristic expressed as average number of cluster/bag, weight of cluster/bag, weight of fruit/cluster and weight of basidiocarp but it had a negative effect on number of fruit per cluster. The interaction of vermicompost at rate 10% and Azolla plants extract was the most effective to obtain maximum values of total yield/bag and fungus biological efficiency.

Field experiments were carried out in two successive seasons of 2019 and 2020, Kafr El Sheikh Governorate, Egypt, to find out the effect of Zinc (Zn) application splits and rateswithout or with humic acid (HA) on rice growth, grain yield and quality. The experiments were laid out in a split-plot based on Randomized Complete Block Design with three replications. Treatments included two application splits were applied in main plots and nine application rates; control (T1), 100% (20 kg ZnSO4.7H2O fed.-1) soil application traditional recommended fertilizer dose (RFD) (T2), foliar Zn application rates of 12.5% (T3), 25% (T4) and 50% (T5 ) from RFD, HA(T6), foliar Zn application rates of 12.5% (T7), 25% (T8) and 50% (T9) from RFD+HA were applied in sub-plots. Results indicated that, Zn application at three splits gave higher rice growth characters, yield components and grain quality than two splits. By increase zinc application rates without or with HA had a significant increase (P <0.05) in growth characters; the highest increase mean values of plant height (7.8%) and number of tillers m-2 (16.5%) were at 25% RFD+HA while, LAI (22.3%) and chlorophyll content (15.8%) were at 50% RFD+HA compared with control treatment. The highest panicle length (19.6 cm), panicle weight (2.29 g), number of filled grains panicle-1 (104.9), grain yield (4.12 t fed.-1),harvest index(47.9%), elongation percentage (32.6%) and head rice percentage (69.4%) recorded at Zn 50% RFD+HA as an average of both seasons.

This experiment was carried out during the two successive winter seasons of 2018/2019 and 2019/2020 at El-Khattara Experimental Farm, Fac. Agric., Zagazig University, Sharkia Governorate, Egypt to study the effect of mineral nitrogen levels and foliar spray with tryptophan amino acid in different concentrations on the growth, yield and quality of lettuce plants cv. Dark green under sandy soil conditions. The best interaction treatment for increasing head weight, total yield and leaf area index was fertilizing plants with mineral nitrogen at 75% of recommended dose (RD) and spraying with tryptophan at 30 ppm. Moreover, fertilizing with 75% N (RD) and spraying with tryptophan at 45 ppm gave the highest values of total dry weight/ plant, N, K and dry matter percentage. In addition, fertilizing lettuce plants with 100% N (RD) and spraying with tryptophan at 30 (ppm) increased P%, whereas the highest nitrate concentration in leaves recorded by the interaction treatment with 100% N (RD) and all tested concentrations of tryptophan. Therefore, fertilizing with 75 % N (RD) and spraying with tryptophan at 30 ppm could be recommended for raising lettuce yield and giving moderate value of nitrate concentration in leaves under conditions of this study.

The effect of postharvest treatments of thyme oil and chitosan under different concentrations and combined with the packaging on weight loss%, firmness, decay index, malondialdehyde(MDA) content, total chlorophyll, hue angle (hº), ripening index, ascorbic acid and pectin methylesterase enzyme(PME) on ‘Etmani’ guava (Psidium guajava L.) fruit, were investigated during 2017 and 2018 successive seasons. Obtained results indicate that weight loss %was diminished by (T7) thyme oil at 1000 μLL−1 + packaging and (T8) chitosan at 1% + packaging, as well as firmness and PME were reduced significantly (p˂0.05) when treated with chitosan at 1% and 2% (T3 and T 4) and thyme oil at 1000 μLL−1 ( T2) compared to control treatment (T0). Simultaneously, it indicated that the most effective treatment in decreasing MDA and decay index were the treatment T3 and T4. Therefore, Chitosan and Thyme oils treatments could maintain normal cell membrane structure and function through down-regulating MDA content and pectin methylesterase enzyme activity, which due to reducing softening, weight loss%, and decay index in guava cv. ‘Etmani’ fruits during storage periods in comparison to other treatments and control

Producing new transformants phosphate bio-stimulate (PBS) bacterial inoculates in addition to study their potential effect on growth, yield and quality of kohlrabi plants at two successive seasons 2017/2018 and 2018/2019 were studied in this present work. The obtained results revealed that using the three tested phosphate bio-stimulate inoculates (PBS1, PBS2 and PBS3) alone or combined with different doses of phosphate mineral fertilizer PMF (calcium superphosphate) increase considerably growth, yield and quality of kohlrabi plants as compared to control. Among all tested PBS inoculates treatments, plants treated with PBS2 was superior and gave the best results in all studied traits when used alone or in combination with PMF doses at both seasons. Applying PBS (1,2 and 3) inoculates alone or combined with PMF doses improved the quality of kohlrabi knobs by increasing the values of total soluble solid TSS%, carbohydrates% and L-ascorbic acid% content in the same time, it decreased significantly the fiber% and nitrate content in knob as compared to the control in both seasons. So it could be recommended that to reduce the actual hazard of mineral fertilizer on soil and human health and to produce safe and healthy vegetable for local market and exportation it should be used PBS inoculates alone or combined with low PMF doses.

A field experiment was carried out during 2015/2016 and 2016/2017 seasons on Egyptian lime trees (Citrus aurantifolia) on orchard located at Al-kamal region, Governorate , Egypt . In this study, the effects of Naphthalene acetic acid (NAA) at different concentrations (0.50, 0.75, 1 .00, 1.25 1.50 %) for suckers growth andimprove fruit quality of lime trees. As a result of the study, spraying NAA highly decreased trunk sprouts. However, the highest concentration (1.50%) recorded the lowest values of number, weight, and length of Suckers during the two growing seasonscompared with the control and removal treatments. In addition, it enhanced vegetative growth parameters as leaf area and chlorophyll content in the leaves in both seasons. Moreover, Spraying NAA at 1.00%achieved the highest values of fruit weight, length, diameter, yield/tree and fruit Acidity % in the two seasons, respectively. Furthermore, NAA at 1.25%increased fruit juice %, TSS % and Ascorbic acid content in fruit juice in the two seasons of study. Peel thickness was reduced as a result of NAA at 1.50%.

A research experiment was conducted after sugar beet harvesting season of 2018/2019 to study the losses in sugar beet roots and reducing it by using different storage methods (shadow and sun light), covering (without, rice straw, sugar beet foliages and net) and spraying treatments (without, tap water and Mepiquat chloride at 0.5, 1.0 and 1.5 cm/L) during storage periods (one, two, three and four weeks) under environmental conditions of Dakahlia Governorate, Egypt. The experiment was carried out in factorial experiment in randomized complete blocks design with three replicates. The highest values of root fresh weight/plant, root length and diameter and infestation percentage and lowest root weight loss percentage were recorded when stored under shading. The highest values of root fresh weight/plant, root length and diameter and lowest root weight loss percentages were recorded when covering root piles with sugar beet foliages, followed by covering with rice straw. The highest values of root fresh weight/plant, root length and diameter and lowest root weight loss percentages and infestation percentages of sugar beet roots were recorded when spraying piles of sugar beet roots with Mepiquat chloride at 1.0 cm/L. It can be concluded that stored sugar beet roots after harvesting directly in piles under shading and covering with beet foliages and spraying piles with Mepiquat chloride at 1.0 cm/L to reduce losses in sugar beet roots after harvesting and during storage and achieve high apparent characters of roots under the environmental conditions of Dakahlia Governorate, Egypt

A field experiment was executed at Kalabsho, Dakahlia Province, Egypt in a sandy loam soil, during 2018/2019 and 2019/2020 seasons, to study the influence of humic acid levels (without, 7.5 and 15 l/fed) and chelated iron levels (without, 0.5 and 1.0 g/l) on sugar beet grown under three hill spaces (15, 20 and 25 cm). A split-split plot design was used. The results cleared that increasing hill spaces from 15 and/or 20 cm to 25 cm had a substantial increase in leaf area index in both seasons, and sugar lost to molasses (SLM) in the 1st one, whereas, extractable sugar%, quality index, sugar and root yields/fed were markedly reduced, in both seasons. Raising humic acid level from 7.5 to 15 l/fed had an appreciable increment in net assimilation rate (NAR),extractable sugar%, sucrose%, root and sugar yields/fed, in both seasons, and quality index in the 1st one, meanwhile, SLM was not affected. The maximum values and statistical increases were detected in root dimensions, photosynthetic pigments, NAR, sucrose%, extractable sugar%, quality index, sugar and root yields/fed, and low impurities content and SLM, when chelated iron concentration was raised to 1.0 g/l. Effects of the significant interactions among the studied factors on the recorded traits were discussed. Under the present work conditions, sowing sugar beet on 15cm and/or 20cm between hills, soil drench with humic acid at 15 l/fed and spraying foliage with 1.0 g Fe-EDDHA/l, can be recommended to get the highest root and sugar yields/fed and the best quality traits.

The investigation was undertaken to determine the combining ability effects different genetic parameters between some rice genotypes. Line x tester mating design was conducted and 12 F1 hybrid combinations were developed from the cross between 3 lines and 4 testers. There was significant difference between parents, crosses and line x tester interaction for the tested traits. Sakha106 was the best general combiners for heading date, while the line GZ9399 was the best for yield and its components. Among the testers, GZ10101 line was adjudged as good general combiner for 1000-grain weight trait. The crosses Giza178 x Egyptian Yasmin and Sakha106 x GZ10101 were the best hybrid based on specific combining effects for the most important traits. The dominance genetic variance (σ2D) was greater than the additive genetic variance (σ2A) in controlling the inheritance of all the studied traits, except flag leaf area was governed by the additive genetic variance. Heritability values are high for plant height and sterility %, indicating slight effects of environment on the traits. On the contrary, the contributions of the lines were higher than the contribution of the testers for no. of panicles/plants, no. of filled grains/panicle, sterility % and grain yield/plant. Cluster analysis divided the seven rice genotypes and their hybrid combinations into two main groups based on morphological traits especially plant height, no. of filled grains/panicle traits and sterility %. Studying of combining abilities is effective in identifying the better parents and helps in the selection of better parent for successful breeding.

Combining Ability of New Yellow Maize Inbred Lines and Superiority of their Hybrids to Check Cultivars
I.
El-Gazzar,
Twenty five new yellow maize inbred lines were top crossed with two testers, i.e. inbred lines; Sk11 and Gz658 during 2016 season at Sakha Agric. Res. Station of Agricultural Research center (ARC), Egypt. The resulting 50 crosses along with two commercial check hybrids ( SC 162 and SC 168) were evaluated in yield trails using a randomized complete block design with four replications at Sakha and Mallawy Agric. Res. Stations (ARC) in 2017 growing season to study the combining ability of these new inbred lines and evaluated the superiority of crosses compered to commercial crosses. Mean squares due to hybrid (H), hybrid × location (H ×Loc.) were highly significant for days to 50% silking, ear position, number of ears/ plant and grain yield/ha. Also, mean squares due to line (L), tester (T) and their interaction (L × T) were significant for all studied traits except for L×T of ear position, number of ears/plant and grain yield. The best inbred line, that revealed desirable GCA effects were Sk5008/27 for earliness, Sk5010/57 for ear position, Sk5010/54 for No. of ears/plant, and Sk5008/31 for grain yield. The best hybrid superiority relative to checks was exhibited by Sk5007/27 × Sk11 for earliness, Sk5010/44 × Sk11 for ear position, Sk5010/58 × Sk11 for No. of ears/plant and Sk5008/31 × Gz658 for grain yield. The 25 inbred lines were classified into two different heterotic groups using HSGCA method for grain yield, group 1 (Sk11) included seven inbred lines and group 2 (Gz658) included seven inbred lines.
