Effect of irrigation frequency and coir pith application in sesame (Sesamum indicum)

Field experiments were conducted during 1992-94 in Irugur soil series at Tr ichy (T.N.) to study the effect of 3 irrigation intervals and incorporation of raw and composted coir pith on sesame (Sesamum indicum). Scheduling of irrigation at 10 days interval and 15 days interval were on par but signifi cantly superior to 20 days interval with regard to seed yield and its compo nents. Composted coir pith application at 10 t/ha combined with 15 days irr igation interval significantly increased growth and yield attributes, seed yield and net income/ha.
