Abstract
The present study was carried out (sandy soil under sprinkler irrigation) in two locations, Mallawy and Assiut, Agricultural Research Stations, Egypt, in two successive winter growing seasons of 2019/2020 and 2020/2021 to evaluate four bread wheat cultivars under four nitrogen levels for grain yield and its components and to identify response and suitable across 16 environments (combination of four soil N levels × two years x two locations) at newly reclaimed sandy soils. A split-plot arrangement with four replicates in each season. The combined analysis of variance showed significant differences among environments, cultivars, and nitrogen levels for all studied characters. Misr 1 had the earliest heading and maturity, and the shortest plants. Shandaweel 1 was superior overall genotypes for plant height, No. of grains spike-1, 1000-grain weight, grain yield, and biological yield followed by Misr 2. Furthermore, the nitrogen level of 125kg N fed-1 (N4) was the best fertilizer level followed by the nitrogen level of 100kg N fed-1 (N3) in sandy soil for recorded the highest values for yield and its components under two locations. The interaction (C x N) was significant for most studied traits under four environments. Cultivar Misr 2 followed by Shandaweel 1 were recorded with the highest values for No. of spikes m-2, No. of grains spike-1, 1000-grain weight, grain yield, and biological yield with level 125 kg N fed-1 (N4) under Mallawy and Assiut locations. According to GGE-biplot, Shandaweel 1 (G1) was the most stable cultivar.
