Combining ability analysis was conducted using line x tester design for seven inbred lines of maize which were crossed to three single crosses as testers at Ismailia Agricultural Research Station during 2016 growing season. In 2017 season, 21 crosses in addition to one check hybrid were evaluated at three locations. Highly significant differences were found between the locations for all studied traits. Mean squares due to crosses, their partitions and their interaction with locations were significant or highly significant for all studied traits, except for lines and lines x testers for number of ears/plant and testers for number of rows/ear. The best inbred lines for general combining ability effects were Gz-8093, Gz-8092 and Gz7253 for earliness and Tep-6240 for grain yield. the tester SC 131 was the best general combiner for days to 50% silking toward earliness, grain yield, number of ears/plant, ear length and ear diameter. The cross Gz-8093 x SC131 had the desirable SCA effects for all traits also. The additive gene effects were more important than the non-additive gene effects in inheritance of days to 50% silking, number of ears/plant, ear length and ear diameter while, the non-additive was more important than additive for grain yield, number of rows/ear and number of kernels/row. The non-additive gene effects were more affected by environment than additive gene effects for all traits except for number of ears/plant. The cross Gz-8093 x SC131 highly significantly outyielded to the TWC 324, suggesting the use of this cross in maize breeding programs.

A split-plot field experiment with three replications was performed at the experimental Farm of Etay El- Baroud Agricultural Research Station, El- Behera Governorate during 2018/2019–2019/2020 seasons to determine optimum irrigation treatments for achieving the highest grain yield of some bread wheat genotypes and determining selection criteria for improving grain yield per plant. The three irrigation treatments i.e. I1= Irrigation at tillering + elongation stage, I2 = Irrigation at tillering + elongation + booting stage, I3 = Irrigation at tillering+ elongation + booting + heading occupied the main plots and six wheat genotypes i.e.; Misr 2, Gemmeiza 11, Misr 1, Shandweel 1, Line 1 and Line 2 were in sub plots. Sowing of cultivar Misr 1 under the second irrigation treatment gave the highest number of spikes/m2 (454.33 spike), number of kernels/spike (56.17 kernel), grain yield (25.48 ardab/fed), and harvest index (38.89%), hence it was the best recommendation for wheat growers. Water Use Efficiency (WUE) was recorded the highest values (1.23) at I1 for Misr 1, which produced the highest grain yield and water use efficiency. Number of kernels/spike (0.61) followed by spike length (0.1846)had the largest direct effect on grain yield, hence, hence they are considered as the best selection traits for improving grain yield as reveled by path analysis. Moreover, multivariate analysis indicated that number of kernels/spike, number of spikes/m2, spike length and 1000-kernel weight could be the reliable criteria for selecting better genotypes in second irrigation treatment (I2).

Ten genotypes of bread wheat were crossed in a line x tester mating design. The twenty-one F1's and their parents (seven lines and three testers) were estimated under three levels of nitrogen fertilizer; low (25 kg N/fed), mid (50 kg N/fed) and normal (75 kg N/fed) in three experiments. Each experiments in a randomized complete block design with three replications at the Experimental Farm, Faculty of Agriculture, Menoufia University, Shebin El-Kom, Egypt during 2019/2020. The results cleared that nitrogen fertilizer levels mean squares were significant for all studied traits. A significant difference was found among lines, testers, line x testers and their interaction with nitrogen levels for all studied traits. Analysis of genetic revealed that GCA and SCA variances were significant for all studied traits under different levels of nitrogen fertilizer, indicating the importance of both additive and non-additive components in the inheritance of these traits. However, the hybrids L1 x T1, L2 x T1, L2 x T3, L3 x T2, L4 x T2, L5 x T2, L6 x T2, L7 x T1and L7 x T3were excellent harmonious combiners for specific combining ability effects for grain yield per plant and most of its components under different nitrogen fertilizer levels. The parental lines 1, 4, 6 and 7 proved to have better general combiners for grain yield per plant and most of its components under different levels of nitrogen. Therefore, these genotypes must be taken care of when breeding to tolerate low levels of nitrogen fertilization.

This Investigation was carried out at Nubaria Agricultural Research Station (30° 54´ N, 29° 57´ E, and 15m above sea level), Agricultural Research Centre (ARC), Ministry of Agriculture and Land Reclamation (MALR), El-Behiera Governorate, Egypt, during 2016-2018 period to study the effects of application liquid humic acid on alfalfa forage yield and quality under irrigation water regime. Three irrigation water regime treatments were100%, 80% and 60% of ETp and three humic acid rates 0, 3 and 6 L/ha humic acid were tested in a strip-plot design. As water requirements decreased forage yield significantly decreased, in the 4 seasons for each year. No significant differences were found between the fresh or dry forage yields or leaf/stem ratio under 100% water requirement without humic acid and 80% water requirement with 6 L/ha humic acid. No significant differences were found between protein content under the interaction between irrigation water requirements and humic acid rate. Irrigation water use efficiency increased under water stress as an application of humic acid rate increased. The previous results indicate that, under experimental conditions, it is possible to save 20% of the amount of added water when adding 6 L/ha humic acid with an insignificant increases in yield amount to 11.421 t /ha.

This work was performed out during the two consecutive winter seasons of 2018/2019 and 2019/2020 in the Research Farm at the Faculty of Agriculture, Al-Azhar Univ., Assiut, Egypt, to study the effect of different rates of phosphorus fertilizers (15.5, 31 and 46.5 Kg. P2O5/fed.) and foliar with amino acids (control, 2 and 4 cm3/L) on growth, yield and its components and seed quality of chickpea cv. Giza-195. The experiments were performed in a split- plot design with three replicates; where phosphorus rates were assigned to the main plot while amino acids were distributed randomly in sub- plot.The obtained results showed that increasing the phosphorus fertilization rates from 15.5, 31 and 46.5 kg P2O5/fed caused a significant increase in all traits under study in both seasons.amino acids foliar increase of application from 0, 2 to 4 cm/L caused significant and gradual increases in all studied characters, i.e. plant height, number of branches and pods/plant, 100-seed weight, seed yield/plant, as well as seed and straw yields/fad. This application also, increased protein percentages in seeds.The study recommended that phosphate fertilization at a rate of 46.5 kg P2O5/fed and spraying with amino acids at a concentration of 4cm/L to obtain the highest yield from the faddan and the highest quality of seeds under Assiut conditions.

Two field experiments were carried out during 2018 and 2019 seasons at the experimental farm of Sakha Agriculture Research Station, Sakha, Kafrelsheikh, Egypt to study the response of three rice varieties namely; EHR1, EHR3 and Giza178 to examine the possible role of exogenous application of SA and P applications under three irrigation intervals; continuous flooding, irrigation every six days and irrigation every nine days. The experiment was performed in a strip split plot design with three replications. Irrigation intervals were subjected in the vertical plots and the rice varieties were allocated in the horizontal plots. The sub-plots were devoted to chemical treatments. The main results of the both seasons were summarized as follows; EHR1 gave the longest heading date and the maximum values of number of tillers m-2, plant height and flag leaf area, EHR3 variety gave the highest values of leaf chlorophyll content, leaf area index, number of total grains panicle-1, 1000-grain weight and grain yield as well as hulling and milling percentages. Giza178 inbred rice cultivar recorded the highest percentages of filled grains and head rice, while, it gave the minimum values of growth parameters, yield attributes and grain yield. Irrigation every 6 days recorded high water use efficiency with a little reduction in grain yield and save some of irrigation water when SA or P was exogenously applied. Nine days interval saved water by 19.09 % and 18.86 % with grain yield reduction of 13.52 % and 14.41 % in both seasons, respectively.

The present study was conducted at the Experimental Farm, Fac., Environ. Agric., Sci., Arish Univ., during successive summer seasons of 2018 and 2019, to screening twenty one genotypes of tomato as well as Galaxy 040 F1 as check to high temperature under North Sinai conditions. The analyses of variance for all studied traits revealed that mean squared of genotypes were highly significant under high average day/night-time temperature (34.6 oC and 23.9 oC, respectively) of two seasons. The studied lines CLN 1621F, Rio Grande and CLN2514A were the best for floral traits. However, the superior genotypes for fruit set percentage were CLN2026D and Rio Grande. Results of screening revealed that CLN2514A was the best for no. fruits/plant, CLN2413D and CLN1466EA for average fruit weight and CLN1621F for fruit yield /plant (2.84 kg). The highest content of proline recorded by CLN1621F and CLN3125L. Tomato genotypes ranked based on cumulative score to tolerant, moderately tolerant, moderately sensitive and sensitive groups. The clustering pattern of tomato entries grouped into five clusters. The clusters 1, 3 and 4 consisted of three genotypes, whereas the clusters 2 and 5 involved nine and four ones, respectively. Principal component analysis revealed that first two components participating 81.3% of total variability. The highest contribution towards total variability in PC1 and PC2 reflected by no. pollen grains/anther, pollen viability%, branches/plant, fruit set%, fruit yield/plant, average fruit weight, no. seeds/fruit and proline content traits, suggesting that these traits might be taken in concern for successful selection of tomato genotypes under high temperature.

The present investigation was carried out during two successive seasons 2019 and 2020 on Flame seedless grapes cultivar grown in sandy soil at private farm, Naga Hamady, Qena Governorate, Egypt. Eight treatments of mineral N, humic acid, organic and biofertilization applied to study the effect of them on vegetative growth, soil nutrient status, and fruiting of Flame seedless grapevines. The experimental vines were arranged in a complete randomized design with eight treatments and three replications two vine per each. The obtained results could be summarized as follow: Using the recommended dose of nitrogen (RDN) via 25 to 50% mineral plus 25 to 50% Humic acid (HA) or compost and bio-mix significantly increased, leaf area, pruning wood weight, and leaf total chlorophyll as well as leaf nutrient composition compared to use RDN via mineral N fertilizer alone. All combined fertilization treatments significantly increased the yield and improved the cluster and berry traits compared to use RDN via mineral source only. The results of this investigation indicated that, most trace element and soil physical and chemical properties were increased with increasing the level of organic, bio fertilization and humic acid in studied soil. Also, it could be concluded that fertilized vines with 25 to 50% of nitrogen requirements plus HA or compost and bio-mix improved the vegetative growth and nutritional status, as well as, yield, cluster attributes and berry quality of Flame seedless grapevines under this experiment circumstances.

Two field trials were carried out in Shandweel Agriculture Research Station, Sohag, Governorate during 2015/2016 and 2016/2017 seasons. This study aimed to investigate the effect of intercropping some garlic varieties in pea varieties field under different garlic planting densities in relation to yield and yield components of both crops. The treatments in which the two varieties of peas and garlic were grown alone individually gave the highest values obtained for most of the vegetative characters, yield and its components. during the two seasons. Intercropping with density of two rows of garlic significantly exceeded the treatments in which garlic was intercropping with a density of one row. Land equivalent ratio (LER) values were greater than one by all intercropping treatments of pea with garlic, in both seasons. Pea2+two rows garlic2 gave the highest values of relative crowding coefficient, while pea1+one row garlic1 gave the lowest values. The intercropping of garlic on the peas led to a decrease in the number of pods infected with E. zinckenella compared to the solo peas plantation for both seasons of agriculture for all varieties. While, the intercropping led to increase the count of thrips on garlic during the intercropping period, the numbers decreased after the peas were removed. Through this study it can be recommended to intercropping garlic, variety Sids-40, at a density of two rows cultivation on the pea of cultivar Intsar 2, to obtain the highest yield compared to other treatments of intercropping.
