Effect of Pre and Early Post Emergence Herbicides on the Growth and Yield of Rainfed Greengram

A field experiment was conducted at Agricultural Research Station, Kovilpatti during kharif 2017 to find out the suitable weed management practices for rainfed greengram. In this study, application of Oxyfluorfen @ 0.10 kg a.i. ha-1 or Pendimethalin @ 0.75 kg a.i. ha-1 as pre emergence + application of Imazethapyr @ 50 g a.i. ha-1 as early post emergence on 20 DAS recorded lowest weed density and dry weight at 15, 30 and 45 DAS and resulted in lower weed dry weight, higher weed control efficiency, higher plant height, grain and haulm yield. Unweeded control treatment produced least grain yield due to its maximum crop weed competition.
