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.

Bio-efficacy of Herbicides on Weed Density, Weed Control Efficiency, Productivity and Groundnut Quality in Coastal Zone of Karnataka under Rice-Groundnut System

“…(1.5 kg ha -1 ) (PE) followed by one hand weeding at 25 DAS (T4) compared to the un-weeded check (44.02% in oil content) and 24.59 per cent in protein content. These results are consistent with findings by Kumara et al [12], Rao et al [13].…”

Marker Assisted Selection in Groundnut

“…Peanuts are key oilseed and food-legume crops for both humans and livestock in tropical and subtropical regions, and globally they are the fourth largest source of edible oil and third most important source vegetable protein. Its seed contain about 50% of edible oil and the remaining 50% of the seed has high quality protein (36.4%), carbohydrate in the range (6-24.9%), minerals and vitamin [2]. It is believed to have originated in the southern Bolivia to northern Argentina region of South America.…”
