Evolving Viable Weed Management Practices for Rainfed Greengram

Abstract

                                A field experiment was conducted at Agricultural Research Station, Kovilpatti during kharif 2017 to study the effect of pre and early post emergence herbicides on weed control in rainfed greengram. In this study, PE Oxyfluorfen @ 0.10 kg ha-1 + EPOE Imazethapyr @ 50 g ha-1 on 20 DAS or PE Pendimethalin @ 0.75 kg ha-1 + EPOE Imazethapyr @ 50 g ha-1 on 20 DAS provided a broad spectrum of weed control by significantly reducing weed density and dry weight at 45 DAS and resulted in higher weed control efficiency and lower weed index. PE application of Oxyfluorfen @ 0.10 kg ha-1 + EPOE application of Imazethapyr @ 50 g ha-1 on 20 DAS or application of Pendimethalin @ 0.75 kg ha-1 + Imazethapyr @ 50 g ha-1 on 20 DAS recorded significant improvement in plant height, yield attributes like number of pods plant-1, number of seeds pod-1, test weight (g) and produced higher grain and haulm yields of rainfed greengram.
