Effect of sowing date on the performance of sesame (Sesamum indicum L.) genotypes under irrigation conditions in northern Sudan.

An experiment was conducted during 2002/2003 season at the experimental farm, Faculty of Agriculture, Nile Valley University, Darmali, Northern Sudan. The objective of the present investigation is to evaluate some promising sesame genotypes under different sowing dates (mid June, early July and mid July). Parameters recorded included that; no. of plants /m height of first capsule, number of branches per plant, number of capsules per plant, 1000seed weight and seed yield per unit area. Results showed that, sowing dates significantly affected no. of plants /m , number of branches, number of capsules per plant, 1000seed weight and seed yield. The highest seed yield was recorded for early July sowing by Shuak genotype.
