Abstract
This field experiment was conducted Split-split plot design was applied. Two durum wheat varieties were assigned to the main plot, micronutrient to the subplots, and seeding rates to the sub-sub plots. The two durum wheat varieties were sown under four levels of seeding rate (100, 125, 150, and 175 kg ha-1). Micronutrients (ZnSO4 and FeSO4) were supplied during the early grain filling stage both at a rate of 25 kg ha-1. The result showed that an increase in the seeding rate up to 175 kg ha-1 caused a significant (P = 0.05) grain yield improvement by about 23.5% and biomass by 21.5%. However, except plant height, most of the yield components like thousand-grain weight, seeds spike-1, spike length, and a number of seeds spike-1 significantly (P = 0.05) decreased markedly with increasing in the seeding rate. The grain qualitative traits such as grain protein content, gluten content, and Zeleny index decreased with the seeding rate increased. The response of the tested varieties was different from the changing seeding rate. Foliar application of FeSO4 has significantly ameliorated grain quality traits. In a dryland environment, the grain protein content was significantly higher than in a wet environment. The study inferred that a higher seeding rate (175 kg ha-1) increased both biomass and grain yield. Optimization of seeding rate was varied from agro-ecology to agro-ecology. Farmers and extension workers, therefore, consider varietal and location differences during seeding rate recommendation.
