| Abstract | ||
| Optimum sowing dates proposed a suitable atmosphere to achieve an outstanding yield. Field and laboratory experiments were performed to evaluate the effect of three sowing dates, namely, November 15th, November 30th, and December 15th, and four cultivars, i.e., Sakha 95, Sakha 94, Misr 3, and the Chinese cultivar Jinqiang 7, on potential yield and wheat seed quality. A split-plot design with three replicates was used. According to the results, late sowing on December 15 caused a great reduction in flag leaf area, number of days to physiological maturity, plant height, number of spikes/m2, number of grains/spike, spike length, 1000 kernel weight, grain yield, wet and dry gluten, as well as crude protein percentage in both seasons. estimated reduction in grain yield of about 31 and 30% in both seasons, respectively. The Sakha 95 cultivar had a significant difference in plant height, number of spikes per m2, grain yield, and wet and dry gluten compared to other cultivars in both seasons. Jinqiang 7 recorded early days to heading, high leaf area, early maturity, and high crude protein. Also, Sakha 94 recorded a high grain yield, thousand kernel weight, and spike length. Tested cultivars could be descendingly arranged according to their grain yield or feddan as follows: Sakha 95, Sakha 94, Misr 3, and Jinqiang 7. The highest grain yield/feddan resulted from sowing the Sakha 95 cultivar on all sowing dates. Significant wheat seed quality parameters were obtained by Sakha 95 when sowing on November 30 in both seasons. These results indicated that sowing Sakha 95 maximizes wheat crop productivity, while delayed sowing recommended sowing Sakha 94 or Misr 3 maximizes yield and wheat seed quality in this experimental environment. | ||
