| Abstract | ||
| A field experiment was carried out at the Agronomy Department Experimental Farm, Faculty of Agriculture, Assiut University, during the growing seasons of 2020/21 and 2021/22 to study the effect of nitrogen fertilizers rates and planting methods on grain yield and its components of six bread wheat cultivars (Misr 2, Sids 14, Gemaiza 11, Shandweel 1, Giza 171 and Sids 12). A randomized complete block design (RCBD) was used in this experiment with three replications using strip - plot arrangement. The planting methods (flat, ridges and raised beds) were arranged horizontally, while nitrogen rates (50, 75 and 100 kg N/fed.) were arranged vertically as well as the tested wheat cultivars were distributed in the sub plots. The results expressed that Gemmeiza 11 cultivar recorded the highest significant mean values of all studied characters (seed index, weight of kernels/spike, grain yield (ardeb/fed.) and straw yield (ton/fed.) ) compared to the other wheat cultivars examined except the number of kernels/spike trait which reacted significantly for Sids 12 in both growing seasons. Furthemore, the application of 100 kg N/fed. recorded the highest significant averge values of grain yield (ardeb/fed.) and straw yield (ton/fed.) in both growing seasons. Also, planting wheat plants on raised beds gained the maximimu mean values of grain and straw yields in both seasons compared with the other tested planting methods. | ||
