| In order to investigate the effect of planting date and cultivar on yield components and physiological traits, split plot was performed in a randomized complete block design with three replications in 2020-2021years at the University of Lorestan. The main factor consisted of four cultivation dates 6 October, 21 October, 5 November, 21 November and the sub-agent of the figure, including Chamran, Sirvan, Mihan. The results of analysis of variance showed that simple effect of planting date on all traits in one percentage probability level and simple effects of cultivar on grain yield, harvest index, number of spikes per square meter, 1000 grain weight and dry matter remobilization at the probability level of a Percent was significant. Planting date on 6 October due to early culture and developmental stages with lower temperatures of plant tolerance and planting date 21 November due to delay during planting and limiting the production of tillers per plant and, as a result of reducing the number of spikes per square meter, grain yield decreased. The highest grain yield with 6976 kg ha-1 was related to the planting date of 5 November and the Mihan cultivar. In general, the history of cultivation, while increasing the optimal conditions for wheat cultivars, provide growth and physiological characteristics of the plant, including photosynthetic components, provide favorable conditions for the more favorable growth of the plant and ultimately increase the event. In the recent study, the Date of Planting 5 November and Mihan cultivar is recommended as the best planting date and cultivar for Khorramabad region and similar climate areas. |
