Response of Some Wheat Varieties to Nitrogen Fertilizer Levels and Seeding Rate at Sharkia Governorate B- Yield and Its Components

Abstract

The field experiments were conducted during 2022/2023 and 2023/2024 seasons to investigate the effect of two wheat cultivars (Giza 171 and Misr 3), three levels of nitrogen fertilization (60, 90 and 120 Kg N/fed) and three seeding rate (30, 60 and 90 Kg /fed) on some agronomic characteristics and grain yield/fed. Results indicated that Masr 3 wheat variety excelled Giza 171cultivar in an important traits such as number of spikes/m², number of grains/spike, 1000 – grains weight and grain yield/fed in both growing seasons and combined data.

Increasing of nitrogen level from 60 up to 120 Kg N/fed. had a significant effect on the traits of No. of spikes/m², No. of grains/spike, 1000-grain weight and grains yield/fed. in both seasons and its combined data 

Grain yield as ton/fed. was affected by nitrogen fertilization, and gradually increased by increasing N level from 60 up to 120 Kg N/fed. in both seasons and its combined data.

In this investigation increasing Seeding rate from 30 to 90 Kg /fed. had a significant effect on all studied traits during studied seasons and combined data.

Seeding rate had a significant increase in grain yield/fed in both seasons and clearly evident that grain yield was increased by increasing the rate of seeds for growing wheat cultivars under this study.

In most cases, the interaction between studied factors i.e. wheat cultivars, nitrogen fertilization and Seeding rate not show any significant effect on the studied characteristics in both seasons and combined data.

Conclusively it can be recommended that by increasing the nitrogen fertilization level of 120 Kg N/fed. and using 90 kg seeds/fed. for increasing the wheat grain yield in the area of Sharkia Governorate under the two used wheat cultivars in this study Misr 3 and Giza 171, respectively.
