| Abstract | ||
| Field studies were conducted during 2003/04 and 2004/05 seasons at the Faculty of Agriculture Farm, Nile Valley University, Darmali, Northern Sudan. The water – use characteristics, performance and yield of sesame (Sesamum indicum L., var. Shuak) were investigated. Treatments consisted of three irrigation intervals (7, 14 and 21 days). Measured traits were number of leaves per plant, height above ground to first capsule, plant height, number of branches per plant, number of capsules per plant, 1000- seed weight and seed yield per unit area. Results revealed that, the number of leaves per plant was increased at 50% flowering and showed a significant (p < 0.01) difference among irrigation intervals. Irrigation regime of 7-day interval gave the highest number of leaves (46-51) per plant. The mean height to first capsule was not significantly (P< 0.01) different due to irrigation intervals. Plant height was decreased with increasing irrigation intervals. While the number of branches per plant was increased with increasing length of irrigation intervals, number of capsules per plant on the other hand was decreased. 1000-seed weight was not significantly affected by irrigation intervals. However, applying irrigation interval of 7 days produced the highest seed yield (836-923 kg/ha) compared to other longer intervals | ||
