Effect of weed management practices on yield, quality and economics of groundnut (Arachis hypogaea L.) during summer season

Abstract

A field experiment was conducted at Agricultural Farm, Institute of Agriculture, Visva-Bharati, Sriniketan, West Bengal on sandy loam soil during pre- kharif season 2018 to study the effect of weed management practices on yield, quality and economics of summer groundnut (Arachis hypogaea L.). The experiment comprising of eight treatments was laid out in a randomized block design with three replications. Among the different herbicides, application of Flumioxazin 50% SL 125 g ha-1 at 1 DAS resulted significantly higher pod yield (2991.02 kg ha-1), haulm yield (2949.18 kg ha-1), oil content (46.27%), gross return ( 143569 ha-1), net return ( 109161 ha-1) and benefit-cost ratio (3.22) over all other herbicidal treatments although weed free check was found most effective to control weeds in groundnut and recorded highest yield and gross return but lower the net return and benefit-cost ratio.
