Abstract:
A field experiment was conducted during the month of June to August, 2021 at Annukudy village, Thiruvarur district, Tamil Nadu. The treatments included of better combinations consisting of physical and chemical method of weed control. The examinations meant the significance of pre-emergence application of Pendimethalin 30% EC @ 1 kg a.i. ha^-1 on 3 DAS + post-emergence application of imazethapyr 10% SL @ 0.05 kg a.i ha^-1 on 21 DAS which could help the harvests in decreasing the different weed population and at last diminished the complete weed biomass which brought about expansion in crop yield.Pre-emergence application of Pendimethalin 30% EC @ 1 kg a.i. ha^-1 on 3 DAS + post-emergence application of imazethapyr 10% SL @ 0.05 kg a.i ha^-1 on 21 DAS recorded the highest weed control index. Higher weed control index under chemical method might be due to effective weed control achieved under these weed treatment in terms of reduced biomass of weeds.
