Abstract
A field experiment was conducted during 2023 at Karunya Institute of Technology and Sciences, Coimbatore, Tamil Nadu, to find out the effect of different tillage management [Minimum tillage (primary tillage only) and Conventional tillage (primary and secondary tillage)] and five weed control treatments [(PE Pendimethalin @ 1.0 kg ha-1, PE Pendimethalin + Imazethapyr (pre-mix) - Valor 32% EC 1.0 kg ha-1, Hand weeding on 15 and 30 DAS, Weed free plot and Un weeded control (weedy check)] on weeds and productivity of green gram (Vigna radiata (L.) Wilczek) during the winter (Rabi). Conventional tillage generally led to taller plants and higher leaf counts compared to minimum tillage, while effective weed management practices, particularly the combination of Pendimethalin and Imazethapyr, resulted in superior growth indices. Additionally, conventional tillage and weed-free conditions significantly enhanced dry matter production and yield parameters of green gram.
