Abstract

Controlling weeds in groundnut by cultural practices, which are time consuming, expensive and laborious. Application of selective pre-emergence herbicides such as oxyfluorfen or alachlor is an usual method for controlling weeds during the early stages, however this allows weeds to emerge at later stages, especially in groundnut. So, The present investigation was framed and carried out during rabi season, 2020–21 on a sandy loamy soil at the Agricultural College Farm, Bapatla to examine the effect of different weed management practices on groundnut. The experiment was set up with nine treatments and three replications in a randomized block design. The outcomes of the experiment revealed that the lowest weed density, dry weight and the highest weed control efficiency were recorded with hand weeding at 20 and 40 DAS, which was at par with alachlor @ 1.5 kg a.i ha-1 as PE fb hand weeding at 30 DAS and fomesafen @ 110g + fluazifop-p-butyl @ 110 g a.i ha-1 as PoE at 20 DAS.

Weed density, dryweight, Plant growth and Yield.

Conclusion

Hand weeding at 20 and 40 DAS (T2) was found to be superior over other treatments in the overall study. Application of propaquizafop @ 50 g + imazethapyr @ 75 g a.i ha-1 as PoE at 20 DAS yielded equivalent pod yield (1986 kg ha-1) to hand weeding at 20 and 40 DAS among the post-emergence herbicides (2287 kg ha-1).
