Abstract: A field experiment was conducted at Research Farm, College of Agriculture, Gwalior, Madhya Pradesh, India during Kharif(rainy) seasons in 2016 to study the efficacy of pre- and Post-emergence herbicides on weeds, growth, yield and yield attributes traits of greengram. The minimum population of narrow and broad leaf weed species were recorded with hand weeding twice at 45 days stages, which was significantly highest weed control of treatments imazethapyr + imezamox (RM) @ 80 g/ ha PoE and pendimethalin + imazethapyr (RM) @ 1000 g/ ha PE at harvest stage. The maximum value of plant height, number of leaves and number of branches per plant; and yield characters number of pods/plant and number of seeds per pod parameters were recorded with Imazethapyr + Imazamox (RM) @ 80g / ha PoE, which was at par with two hand weeding at 20 and 40 DAS. It was followed by Pendimethalin + imazethapyr (RM) @ 750 g a. i./ ha PE. Weed free treatment provided the highest grain yield, gross returns and net returns. Among the herbicides, preemergence application of pre-mix imazethapyr + imezamox (RM) at 80 g per ha recorded higher grain yield (972 kg/ha) and provided higher net returns (Rs. 42490/-) and B:C ratio (3.18) than the other treatments of herbicides due to significant reduction in the dry weight of weeds and higher weed control efficiency and consequently improving the yield attributing parameters.
