Abstract
To determine the effects of different seeding rates and nitrogen fertilizer levels on yield and its components of six bread wheat genotypes, a field experiment was conducted at East Canal and Al Marashda Agricultural Research Stations during the 2018-2019 and 2019-2020 growing seasons. The experiment was laid out in a split-split plot arrangement in a Randomized Complete Block Design with three replications. Seeding rates (60, 80, and 100 kg fad. -1) were placed in the main plots, while nitrogen fertilizer levels (75,100 and 125 kg N fad. -1) were allotted in the subplots, whereas, the sub-sub plots were allocated to the bread wheat genotypes (Gemmeiza 12, Sids 14, Shandaweel 1, Line 1, Line 2 and Line 3). The number of spikes m-2, 1000 kernels weight, and grain yield were significantly higher at a seeding rate of 100 kg fad. -1 as compared to other seeding rates. Nitrogen fertilizer levels affected significantly yield and its components. Grain yield and its components increased with each increment in nitrogen fertilizer level from 75 to 100 and up to 125 kg N fad-1. Wheat is sown at a seeding rate of 100 kg fad. -1 with 125 kg N fad. -1 has the highest number of spikes m-2 and grain yield.  The interaction effects of seeding rate by genotypes and nitrogen levels by genotypes reveal the superiority of Sids 14 and Shandaweel 1 wheat cultivars in grain yield when sown at a seeding rate of 100 kg fad. -1 with 125 kg N fad. -1 in both locations.
