Abstract

A two-year field trial was conducted at Arakeri village, Vijayapur district in Vertisols during Kharif 2019-20 and 2020-21 to study the effect of nipping on pigeonpea under rainfed conditions of north Karnataka with the aim of finding profitable stage for nipping. Adopting nipping using solar operated tool and hand nipping increased the grain yield by 36.80, 13.61 per cent for 2019-20 and 36.14, 20.48 percent for 2020-21 respectively over farmer’s practice. Significant reduction in plant height was seen in nipped plots than farmer’s practice. The increase in grain yield indicates that nipping using solar operated tool could be effective treatment for pigeonpea in Vertisols. Higher gross and net returns with greater BC ratio was observed with nipping using solar operated tool followed by hand nipping technology.
