| Abstract | ||||
| Wheat cultivar Giza 171 (Triticum aestivum L.) was grown on newly reclaimed sandy soil in the area of Al Ghurairah Village, Esna City, Luxor Governorate, Upper Egypt, during the 2018/19 and 2019/20 seasons, to study the effect of adding nitrogen fertilizer rates (240, 285 and 330 kg N ha-1) in different doses (3, 4, 5, 6 and 7 times before heading date) on wheat productivity. Adding the high rate of 330 kg N ha-1 resulted in a significant increase in plant height, spikes number m-2, grains number spike-1, biological yield, straw yield, and grain yield compared with the low rate of 240 kg N ha-1 in both seasons. The most mentioned traits had no significant difference between 330 and 285 kg N ha-1. The inverse was true in 1000-grain weight, where increasing nitrogen rate reduced it. The nitrogen rate did not affect the weight of spike grains. Splitting nitrogen fertilizer into many doses significantly affected the most studied traits in both seasons. An increasing number of N dose additions from 3 to 7 times gradually increased plant height, spikes number m-2, grains number spike-1, biological yield, straw yield, and grain yield without significant differences between 6 and 7 times in most cases. The inverse was true in 1000-grain weight, where the increase in N doses reduced it. Splitting N into many doses did not affect the weight of spike grains. The interaction between N rates and dose times significantly affected spikes number m-2, grains number spike-1, 1000-grain weight, biological yield, straw yield, and grain yield in both seasons. Adding 330 kg N ha-1 in seven doses produced the maximum grain yield (t ha-1) in the two seasons. Adding 330 or 285 kg N ha-1 in 5, 6, and 7 doses did not differ in grain yield. | ||||
