High NaCl salinity level, induced ultrastructural alterations in leaflet mesophyll cells such as swelling thylakoids, disintegration of grana staking, increase number of plastoglobuli and starch grains as well as increase the size and number of mitochondria and its structure, shrinkage the plasma membranes, increase the Myelin-Like, membrane vesicles formation and increase the thickness of cell wall. In addition, roots immersion into H2O2 led to maintain the chloroplast structure, grana staking and increase the size of chloroplast and mitochondria, decrease the number and size of starch grains and plastoglobuli, decrease the number of membrane vesicles and peroxisomes, as well as maintain the cell wall structural and reduced its thickness. Furthermore, the high NaCl level led to increase the number of stomata and stomatal density and decreased the dimensions of stomatal pore. On the contrary, roots immersion into H2O2 decreases the stomatal density and its number. Concerning the leaflet anatomy, it was found that low NaCl salinity level increased the dimensions of midrib region, main vascular bundle as well as the thickness of palisade parenchyma. While, high salinity level, in most cases, decreased all these parameters.

Parents, F1 and F2 were evaluated for quantitative traits in 2016/2017 season. Significant genotype mean squares and its components (parents and crosses) were obtained for all traits in both generations. Significant heterosis in F1 generation was obtained for all studied traits. Heterosis of grain yield/plant relative to mid parent varied from 4.64 to 75.50% in F1 crosses. The P2xP3, P1xP4 and P2xP5 were the best crosses for grain yield heterosis. General (GCA) and specific (SCA) combining ability mean squares were significant for all traits. MS (GCA)/ MS (SCA) ratios indicated the relative importance of additive and non-additive gene action in their inheritance for all the traits.

The aim of the investigation was to study the effect of nitrogen fertilizer sources (solid and gaseous) under different nitrogen rates (80, 100, 120 and 140 kg N fed-1) on yield, yield components, NPK concentrations and N use efficiency for some maize hybrids (SC 131, SC 168 and SC 176). Experimental design was strip-split plot design with four replications where nitrogen sources distribute in the vertical- plots while, nitrogen rates assigned to the horizontal- plots within N sources. Hybrids were randomly distributed in the sub - plots. Injection ammonia gas gave the lower significant averages value of number days from planting to 50% tasseling (DTT) and number of days from planting to 50% silking (DTS), but increased significantly in plant height (PHT), leaf area index (LAI), chlorophyll content (CHL), No. of ears per plot (EAR), grain yield (GY) and ear length (EL) in the two successive seasons as compared to those obtained with ammonium nitrate (AN) form. Results revealed that the application of AA was associated with significantly higher in kernel per row (KPR) and weight of 100-grains (KWT) than AN. No significant difference between the nitrogen sources was found in ear diameter (CD) in both seasons. Increasing N rates from 80 to 140 kg fed-1 caused a significant increase in DTT, DTS and EAR traits in 2016 only. However, increasing N rate significantly effect on PHT, LAI, CHL, GY, EL, KPR and KWT traits. Significant differences were found among maize single crosses for all tested growth characters and grain yield. Single cross 176 was the earliest hybrid while SC 168 was the latest concerning DTT and DTS in both seasons. Single cross 131 gave the highest value in GY, while SC 176 was the lowest value. Anhydrous ammonia (AA) had higher GY productive under all NR than AN with linear positive significant increase during the growing season of 2015. The highest grain yield was 36.9 ard fed-1 under 140 kg N fed-1 of AA while the lowest value was 24.0 ard fed-1 for AN at 80 kg N fed-1. Single cross 131 had the highest significant value in grain yield under AA, while SC 176 was the lowest value under AN fertilizer. Concentration of grain nitrogen (Nconc), phosphorus (Pconc), potassium (Kconc), their uptake (NPKuptake) and nitrogen use efficiency (NUE) were affected positively by the sources of N fertilizers applied in the two successive seasons. Ammonia gas (AA) enhanced all nutritional parameters comparing with AN. Three way interactions of the tested NS, NR and maize HB agreed with all previous results of main. In general SC 131 followed by SC 168 respond efficiently more than SC 176 to AA comparing with AN under all four N rates up to 140 kg N fed-1.

The experimental study was conducted at El-Baramoon Research Station, Horticulture Research Institute during the two summer season of 2016 and 2017. Six inbred lines selected from Eskandrani cultivar and fifteen F1 hybrids were evaluated for different traits. Significant differences were observed among the hybrids and their parents for all studied traits. Based on mid-parent heterosis, the hybrid (P5 x P6) gave the highest value for early yield per plant (98.51 %) followed by the hybrid (P1 x P4) (90.24%) for the same trait. While heterosis over better parent, the hybrid (P1 x P6) gave the highest value for early yield per plant (78.95 %) followed by the hybrid (P5 x P6) (73.91 %) for the same trait. Furthermore, the highest mid-parent hertrosis for total yield per plant was obtained by the hybrid P4 x P6 (75.0%) followed by P5 x P6 (60.38%) and P4 x P5 (59.65%). Otherwise, the largest heterosis over better parent for total yield per plant were expressed by P4 x P6(61.77%) followed by P4 x P5 (46.77%) and P5 x P6 (37.10%), respectively. General combining ability (GCA) was significant or highly significant for all traits except for early yield per plant and shape index, specific combining ability was highly significant for all traits except for number of node female flower and early yield per plant. The estimated GCA/SCA mean squares revealed that the additive gene effects were the major effect in the inheritance of all studied traits, except for early yield per plant and vitamin C. Also, GCA estimates were larger than their corresponding estimates of SCA for most of the studied traits.

Four NPK fertilizer ratios (1.0:1.0:1.0; 1.0:1.0:0.5; 1.0:0.5:1.0 and1.0:0.5:0.5) with three fertilizer rates (50, 100 and 150 kg fed-1) as a soil application were tested. Each experiment comprised of 12 treatments and were designed as split plots and replicated three times in a randomized complete blocks design. The obtained data of this investigation clearly demonstrated that, all studied parameters such as vegetative growth characters (i.e., plant height and leaves number, plant leaf area, leaves fresh weight and leaves dry matter percentage), leaves chemical composition (viz.
