Evaluation of economic cropping systems for Cauvery Delta Zone
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.
