Abstract:
A field experiment was conducted during the rabi season of 2020-21 in the Agricultural Farm of the Institute of Agriculture (Palli Siksha Bhavana), Visva-Bharati, Sriniketan, Birbhum, West Bengal. The experiment was laid out in randomized block design with nine treatments each were replicated thrice, the treatments are T₁ - Imazethapyr 30 gha^-1 as PE, T₂ -Imazethapyr 40 gha^-1 as PE, T₃ - Imazethapyr 50 gha^-1 as PE, T₄ - Imazethapyr 30 gha^-1 as POE, T₅- Imazethapyr 40 gha^-1 as POE, T₆ - Imazethapyr 50 gha^-1 as POE, T₇ -Pendimetalin 750 gha^-1 as PE, T₈ – Weed-free, T₉ - Weedy check. The experimental results clearly indicated the need for different weed management practices to reduce the influence of weeds in chickpea cultivation. Among the Imazethapyr treatments, Imazethapyr 50 gha^-1 as POE recorded the lowest density and dry weight of weeds, higher weed control efficiency (64.42%), which resulted in higher growth parameters, yield attributes, and higher seed and stover yield. Herbicides controlled weeds to a greater extent. Weed infestation caused about a 79.16% reduction in yield in chickpea crops. And among the herbicidal treatments, the pendimethalin 750 gha^-1 PE (T₇) showed better results and gives good economic values.
