Influence of different weed management practices on yield and nutrient dynamics in groundnut

Abstract

A field experiment was conducted during rabi season, 2020–21 on a sandy loamy soil at the agricultural college farm, Bapatla to evaluate different post emergence herbicides on the yield and nutrient uptake under different post emergence herbicide treatments in groundnut. The experiment was laid out in randomized block design with nine treatments and three replications. Hand weeding twice at 20 and 40 DAS was recorded the lower density and dry matter of weeds followed by Alachlor @ 1.5 kg a.i ha-1as PE fb hand weeding at 30 DAS. Hand weeding twice at 20 and 40 DAS, recorded the lowest uptake of N, P and K by weeds and the highest uptake of N, P and K by groundnut crop.
