Abstract: Choosing an appropriate sowing date for a crop is one of the most important factors in its production when it is cultivated for the first time in a region. In order to study the effect of sowing date on Seed Yield and its Components, two sesame cultivars, an experiment was conducted as factorial with randomized complete blocks design with four replications at Faculty of Agriculture , Kassala University during 2014/2015 and 2015/ 2016 seasons in the Halfah Elgadidah, Sudan . Experimental factors including: four sowing dates (S1, S2, S3 and S4) corresponding to 1rst Nov,15th Nov, 1rst Dec and 15th Dec and two diverse sesame cultivars “Promo” V1, Um shagara as local cv V2. The results showed that both cultivar and sowing date had significant effects on biological yield, leaf area, number of branches and pods per plant, 1000-seed weight and Seed yield (V1) had a significantly greater biological and seed yield per plant than (V2) particularly when sown during S3 but V2 had greater leaf area, number of branches per plant and seed yield per unit area during S3. Also, significant strong positive correlation between biological yield and yield components indicated the increased in seeds weight per plant. Therefore, it is recommended that local cultivar Umshagara sown on first Dec. for improved biomass productivity under irrigation in the study area.
