اثر تاریخ کاشت و زمان برداشت بر عملکرد و اجزای عملکرد لوبیا قرمز در شهرکرد

In order to evaluate the effect of planting date and harvest time on yield and yield components of red bean in Shahre-kord planting date and harvest time on yield and yield components of red bean in Shahre-kord, a split plot factorial experiment in a randomized block design with three replications was conducted at the Research field of Shahrekord University. In this experiment, three planting dates include May 25, June 5 and June 15 as the main factor and two red bean cultivars (Naz and Derakhshan) and two harvest times (in R8 and R9 stages) as factorial were examined as sub plots. Results showed that all traits except seed weight was affected by sowing date and with delay in planting date their values decreased significantly. The effect of harvest time on all traits was significant. According to the results of this experiment and the climatic conditions of the region, to achieve maximum yield, in addition to observing agronomic principles, planting at May 25 and harvested at R9 is recommended.
