Abstract:
Chisel plow and broad bed furrow (BBF) were evaluated in ten farmer’s fields during rainy-winter (kharif-rabi) seasons of 2019-20 and 2020-21 in Vertisols at Vijayapur, Karnataka. Adopting Chisel plow and BBF increased the grain yield by 31.63, 15.08 per cent for 2019-20 and 29.76, 21.66 percent for 2020-21 respectively over farmer’s practice. The increase in grain yield indicates that chisel plowing is effective for insitu rainwater conservation and improving profile soil moisture in Vertisols. However chisel plow technology conserved higher soil moisture as compared to broad bed furrow and farmer’s practice over the entire crop growth period. Higher gross and net returns with greater B:C ratio was observed with layout of farmers fields with chisel plowing technology.
