Response of summer sesame (Sesamum indicum) to irrigation

A field study was conducted during summer season of 1995 and 1996 at Kakdwi p, West Bengal, involving 6 levels of irrigation. In sesame (Sesamum indicu m L.) cv. 'B 67' ('Tilottama'), increase in the levels of irrigation from 1 to 3 increased all growth attributes and yield components. Three irrigatio ns 1 each applied at branching, flowering and capsule-development stages re corded maximum yield (seed + oil) of sesame, followed by 2 irrigations (bra nching + flowering). Three irrigations also increased the content and uptak e of NPK by sesame plant. Consumptive use and water-use efficiency were als o increased with the increase in the irrigation levels.
