Abstract

A study was made to determine the affect of methods of irrigation viz, Beds and channels, ridges and furrows, alternate ridges and furrows and broad bed with two intervals of rrigation (once in 20 and 30 days) and farmer's method (irrigating in beds and channel once in 15 days) as control on sesamum. The yield attributes like number of capsules present on the mainstem, primary and secondary branches were increased by lower levels of moisture in alternate furrows and broad bed system irrigating once in 20 days. Capsule length was significantly increased by higher moisture levels. Higher seed yield was recorded in alternate furrows-irrigating once in 20 days followed by ridges and furrows-irrigating once in 30 days at both the centres. Hence, rirrigating in alternate furrows once in 20 days may be considered as optimum for sesamum.
