| Abstract | ||
| Two field Experiments were conducted during 2021/2022 and 2022/2022 seasons at the Experimental Farm of El-Mataana, Agric. Res. Station, Luxor Governorate, ARC, Egypt. The study aimed to investigate the response of some wheat cultivars namely Misr 2, Gemmiza 11 and Giza 171to seven forms of urea included Common urea, Urea Zewal, Urea Zewal 3, Humic acid coated urea, Biochar coated urea, Cement coated urea, Phosphate coated urea. The experiment utilized a randomized complete block design (RCBD) with split-plot arrangement with three replications. Cultivars were randomized in main plots and forms urea in sub-plots. Wheat cultivars differed significantly regarding their plant height, spike length, number of spikelets/spike, number of grains/spike, grain weight of spike, as well as grain and straw yield per fed.The cultivar Gimmaza 11 gave the highest values for all the previous traits under study. The application of different sources of N fertilizer led to significantly different for all studied traits in the first and second seasons. The highest mean values of most traits were obtained from the application of humic acid coated urea. The interaction effect of V × T showed significant variation on grain yield/fed in both seasons. In the first and second seasons, respectively, the interaction V2 × T4 had the highest grain yield/fed (27.91 and 28.80 Ardb). | ||
