Study certified wheat (Triticum aestivum L.) cultivars response to different planting date to evaluate the active products yield

Planting dates are very important in agriculture because of related to temperatures throughout the wheat growing season. Thus, wheat cultivars should be chosen which fit the best planting date to reach the optimum yield. Therefore, this study aimed to choose the best certified cultivars that can be planted in best sowing date depending upon the global changing in Thi-Qar area in southern Iraq to get the optimum yield of grain yield and protein as active product. Four certified cultivars of wheat (Bohoth 22, Al-Rasheed, Tamooz 2 and Iraq) were planted in four sowing dates (1st Nov., 20th Nov, 10th Dec., and 30th Dec.) that arranged in factorial experiment by using randomized complete block design in three replicates. Bohoth 22 cultivar produced the highest grain yield in the second planting date as well as Iraq cultivar gave the highest protein percentage in the second planting date. Throughout the results of this study, it is clear to understand that all cultivars might be chosen and planted in all planting date in study area because stability of production under the sever environmental conditions.
