A field experiment was applied at the research station in Al-Najmi district, Al-Muthanna governorate during the agricultural season 2020-2021, to determine evaluating several cultivars of wheat by changing the date of their cultivation. The experiment was applied using the split plot using the Randomized complete Block Design(RCBD) with three replicates experiment method, where the planting dates were occupied (1/11, 15/11, 1/12 and 12/15) the main plots, while the cultivars (Baghdad, Furat, Rashid, and Wafia) occupied the secondary plots and with three replicates. The results showed that the planting date (1/12) was superior to the number of days up to 75% of flowering, the number of spikes. m −2 , and the grain yield ton. ha −1 , which amounted to 109 days, 409.9 spikes and 5.77 tons, respectively. While the planting date (15/11) exceeded in both characteristics the leaf area and the number of grains in the spike, as it reached 46.18 cm and 49.78 grains. As for the cultivaries, the Baghdad cultivar surpassed in the characteristics of the area of the flag leaf, the number of fertile spikes, the number of grains per spike, and the grain yield, which reached 44.70 cm, 395.7 spikes.m−2, 48.38 grains, spike−1 and 6.16 tons.ha −1 , respectively.
