تعیین مناسبترین تاریخ کاشت و بررسی اثر آن بر برخی خصوصیات مورفولوژیکی و درصد روغن سه رقم کنجد در استان بوشهر

Determining the optimum planting date for each cultivar is the most important crop management to increase yield and quality, due to differences in climate and cultivar properties. To study the effect of sowing date on some morphological characteristics and oil percent of three varieties of Sesame in Bushehr province, an experiment in completely randomized blocks design (factorial) with three replications was done. The factors were as follows: Sesame cultivars ( dashtestan 2, lanes 5 and the local population) and different planting date [early time (21st June), on time (5th July) and late time (20th July)]. The study was located in Bushehr Research Center for Agriculture and Natural Resources, during the crop period in 2013. Results showed that planting dashtestan 2 in early June had maximum mean height with 163.73 cm. The highest oil was obtained in late time planting with 55.18 percent in lanes
5.Dashtestan2 with an average of 8.02 of branches per plant had the highest number of branches. Early time and late planting time, with average of 8.40 and 7.93 numbers of branches per plant proved statistically significant difference related to late time planting with the mean of 5.44.
