Abstract :
To determine the effect of planting date on yield and yield components of six wheat cultivars with different growth types, a research was conducted in split plot based on randomized complete block design with three replications during two growing seasons of 2016 and 2017 in Mobarakeh region, Iran. Three planting dates of 12 October, 11 November and 11 December were considered as early, usual, and delay planting dates, respectively. Wheat cultivars were Pishgam and Alvand with mid-growth habit, Zare and Heidari with winter habit and Pishtaz and Sirvan with spring growth habit. Early and delay planting cultivars with spring and winter growth habits resulted in yield increasing and decreasing, respectively. The yield of cultivars with intermediate growth type had no significant differences in planting dates of 12 October and 11 November, but the delay in planting caused the loss of yield in these cultivars. Therefore, it is recommended to plant cultivars with spring and winter growth habits and cultivars with intermediate growth type from mid-October to mid-November in the temperate region of Mobarakeh and to avoid delay in planting them.
