Abstract

Field experiment was conducted during rainy (kharif) season of 2010 to evaluate the bio-efficacy of herbicides in groundnut crop on sandy loam soil of Allahabad. The lowest weed density and biomass were recorded with one hand weeding at 20 days after sowing (DAS) followed by application of oxyfluorfen 100 ml/ ha as pre-emergence at (2 DAS). Among the herbicidal treatments the alone application of oxyfluorfen was found most effective in reducing the weed population and dry matter accumulation and gave highest net return (Rs37575/ ha) and the benefit-cost ratio (2.38).
