Afield experiment was conducted at the Research station of the college of Agriculture - University of Al-Muthanna, in the Northeast of Al-Muthanna Governorate (9 km from center of the city of Samawa), in the seasons (2018-2019) and (2019-2020), to study the effect of four harvest dates and four varieties of wheat on yield and quality characteristics, The experiment was applied according to split-plots design Using the R.C.B.D with three replications, The results of the analysis showed the Significant effect of harvest dates on all studied traits, as the date of the third harvest increased by giving the highest grain yield of 5.01 and 5.32 t h −1 for the two seasons respectively, while the fourth harvest date was superior by giving the highest percentage of dry gluten in the first season amounted to 11.66%. As for the effect of the cultivars, it was noticed that the Babel cultivar was superior in grain yield of 4.81 and 5.04 t ha −1 , for the two seasons respectively, while the Bora cultivar gave the highest average weight of 1000 grains for the second season which amounted to 32.68 g, and the percentage of protein in the grains was 12.83% for the second season, and Ash was 1.90 and 1.85% for the two seasons sequentially, while the interaction of the fourth harvest date with Babel cultivar was superior by giving highest weight of 1000 grains in the first season amounted to 33.41 m, while the interaction of the first harvest date with Bora cultivar in the vital yield first season was 16.6 t h −1 .
