Effect of planting date on yield and yield components of sesame cultivars in Miyaneh region, Iran

This study was conducted to evaluate the effect of three planting dates (20 June, 6 and 21 July) on yield and yield components of five sesame cultivars (Moghanl7, Naz, Karajl, Behbahan, and Yekta) in Miyaneh agricultural research station in three replications. Dry weight of different organs of plant, and morphological attributes like as capsule numbers, 1000 kernel weight, protein percentage, yield and yield components was measured in a RCBD base factorial design. There was significant differences among cultivars and planting dates on capsule numbers, protein percentage, biomass, and grain yield of sesame cultivars. The highest yield belonged to Yekta and the least one belonged to Naz cultivar. The first planting date (20 June) also showed higher yield than others did. Based on the results, planting of Yekta cultivar at first planting date could be recommended in Miyaneh and similar climatic regions.
