| Abstract | ||||
| Two field experiments were conducted at Ismailia Agricultural Research station during 2000 and 2001 seasons to study the effect of some irrigation treatments on yield and yield components and seed oil percentage as well as some water relations of sesame variety Giza 32. Nine irrigation treatments represent the combination between three irrigation intervals i.e. 4,6 and 8 days both at initiative capsules stage and maturity. Results showed that significant differences between irrigation treatments for plant height, fruiting zone length, number of capsules/plant, 1000 - seed weight, seed and straw yields/fed. Sesame was irrigated at long intervals (8 days) decreased yield and its components than irrigated at short intervals (4 days) in sandy soil. Results also indicated that increasing water stress at any development stage led to decreased seed oil percentage in sesame seeds. Results showed that increasing irrigation interval of sesame led to decreased seasonal, monthly and daily consumptive use and water use efficiency. It was shown that irrigation of sesame at 4 days intervals during the growing season gave the highest seed yield/fed and water use efficiency in both seasons. | ||||
