Abstract

An experiment was conducted during 1996–2001 at Soil and Water Management Research Institute, Thanjavur for evolving more economic cropping system for cauvery delta zone with 9 cropping sequences. The five years experiment revealed that Rice + Sesbania rostrata direct sowing (DS) at 10:1 in kharif - Rice + Sesbania rostrata direct sowing (DS) at 10:1 in Rabi - Redgram in summer recorded the maximum rice grain equivalent yield of 14,356 kg/ha/yr with net income of Rs. 51,054/- ha/yr and BC ratio of 3.2 and it was comparable with rice - rice - redgram and Rice + Sesbania rostrata transplanting (TP) at 10:1 in kharif - Rice + Sesbania rostrata transplanting (TP) at 10:1 in Rabi and Sesame in summer.
