| Abstract | ||
| A field experiments was conducted during 2022/2023 and 2023/2024 of growing seasons to investigate the effect of the effect of three levels of nitrogen fertilization (60, 90 and 120 Kg N/fed.) and three seeding rates (30, 60 and 90 Kg /fed.) on some agronomy characteristics and grain yield/fed. on some wheat cultivars. The results did not show any significant differences between the two studied cultivars in the traits of plant height No. of days to heading, leaf area, dry weight, plant and spike length in both seasons and their combined data. Nitrogen fertilizer had a significant effect on the trait of plant height in both seasons and combined analysis of data. Meanwhile, did not affect significantly of the traits of leaf area/plant and dry weight/plant. Increasing seeding rate from 30 to 90 Kg/fed had a significant effect on all studied traits during studied seasons and combined data. Conclusively, for increasing the wheat yield in the area of Sharkia Governorate for the two wheat cultivars used in this study it is necessary to use nitrogen fertilizer levels at 120 kg N/fed. and 90 Kg seeds/fed. | ||
