Abstract:
A study was conducted in the vertisols of Vijayapur district, Karnataka to evaluate the performance of chisel plough and broad bed furrow (BBF) in ten farmer’s fields during rainy-winter (kharif-rabi) seasons of 2021-22 and 2022-23. Adopting chisel plough and BBF increased the grain yield by 29.76, 16.04 percent for 2021-22 and 32.16, 19.29 percent for 2022-23, respectively over farmer’s practice. The increase in grain yield indicates that chisel ploughing is effective for insitu rainwater conservation and improving profile soil moisture in Vertisols. However chisel plough 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 ploughing technology.
