Influence of herbicide-based integrated weed management strategies on growth and yield of fenugreek (Trigonella foenum-graecum L.) it Indogangetic plains

Abstract

In the present study, a field experiment was conducted over two years to evaluate the efficacy and economic performance of imidazolinones. The combined application of imidazolinones with pendimethalin exhibited enhanced effectiveness in controlling the weed populations compared to their individual application. PRE application of pendimethalin + imazethapyr (Ready mix) at 1500 g ha^-1, followed by one hoeing at 3-4 leaf stage, proved highly effective in suppressing the dominant weed flora and recorded higher growth parameters and significantly increased the seed yield of fenugreek. Moreover, it emerged as a profitable alternative to the current recommendation of weed control in fenugreek, which involves two hoeing sessions at 25 and 45 days after sowing (DAS).
