Abstract

An experiment was conducted during summer 1984 and 1985 at Tanjore and at Bhavanisagar respectively to study the effects of methods of irrigation on physiological attributes and yield of sesamum. Increase in dry matter production was noted with increasing levels of moisture supply. Maximum leaf area index was noticed at control and beds and channels irrigating once in 20 days followed by once in 30 days. Higher seed yield was recorded in alternate furrow-irrigating once in 20 days followed by ridges and furrows-irrigating once in 30 days at both the centers. Hence, irrigating in alternate furrows once in 20 days may be considered as optimum for sesamum.
