Abstract
Weed infestation in the field crops is one of the major problems faced by the farmers in crop cultivation. Slow growth habit of legumes during early crop growth stages encourages rapid growth of weeds and leads to severe crop-weed competition which finally reduce the crop yield. An experiment was executed during kharif seasons of 2011 and 2012 at Chandamari Village (22º57’N, 88º20’E) of Nadia district of West Bengal to study the effect of Imazethapyr in controlling the predominant weeds in groundnut (Arachis hypogaea). The experiment was laid out in randomized block design with eight different treatments replicated thrice. Pod as well as haulm yield of groundnut was found to be the highest where hand weeding was practiced at an interval of 20 and 40 DAS (T ) and it was at par with the treatment T (Imazethapyr 10% SL @ 125 g a.i. ha-1) for pod yield and T and T 7 3 3 2 (Imazethapyr 10% SL @ 100 g a.i. ha-1) for pod and haulm yield. Though the maximum suppression of targeted weed density vis-à- vis weed biomass was obtained with the T (Imazethapyr 10% SL @ 150 g a.i. ha-1), it showed delayed maturity due to bit 4 phytotoxicity on groundnut
