| Abstract | ||
| A factorial experiment was carried out according to the randomized complete block design (RCBD) with three replications during the winter season for the years 2021-2022 and 2022-2023. The first factor included encapsulating the seeds with plaster, which included two treatments: no seed encapsulation and encapsulation denoted by G0 and G1 sequentially, while the second factor included stimulating the seeds for a period of 16 h (based on to the results of the first laboratory experiment) with nano nitrogen concentrations of 0, 2, and 3 mg L-1, coded N0, N2, and N3, respectively, while the third factor included four varieties of wheat (Mawadda, Tammuz, Ibaa-99, and Buhouth-22) coded V1, V2 V3, and V4, respectively. The results of this experiment showed the following: - The treatment of covering seeds with plaster had a significant (G1) superiority in plant height, number of tillers, number of spikes, number of grains per spike and grain yield for the two seasons of the study, respectively (105.45 and 109.08 cm, 493.3 and 497.8 tiller m-2, and 403.6 and 412.8 spikes m-2). 2, 48.05 and 50.93 grains of spike-1 and 4.927 and 5.215 t h-1) for the two study seasons, respectively. - The treatment of seed stimulation with nano-nitrogen at a concentration of 2 mg L-1 (N2) was significantly superior in plant height, number of tillers, number of spikes, number of grains per spike, and grain yield (104.43, 113.96 cm, 501.2, 505.5 tiller m-2, 401.6, 394.8 spikes m-2, 48.79, 53.01 grains of spike-1, 4.927 and 5.082 t h-1) for the two study seasons, respectively. The cultivar IPA-99 (V3) was significantly superior in plant height, number of tillers, number of spikes, number of grains per spike, and grain yield (106.75, 111.64 cm, 512.2, 506.4 tiller m-2, 405.5, 393.7 spikes M-2, 48. 47 and 51.94 grains of spike-1, 4.900 and 5.069 t h-1) for the two study seasons, respectively. | ||
