Abstract
A field experiment was conducted during the month of June to August, 2021 at Annukudy village, Thiruvarur district, Tamilnadu. The treatments included of best combinations consisting of physical and chemical method of weed control. The studies signified the importance 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 benefit the crops in reducing the different weed density and ultimately reduced the total weed biomass which resulted in increase 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 seed and haulm yield under chemical method might be due to maintenance of weed free environment, particularly throughout vital growth stages of crop, cut back crop weed competition helped in higher growth and development of greengram crop leading to higher seed and haulm yield. The higher yield attributes and yield of irrigated greengram was recorded with 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.
