Weed Management in Kharif Groundnut

A field experiment was conducted on medium black soil to study the effect of different treatments of weed control on groundnut (Arachis hypogaea) yield at Dry Farming Research Station, Junagadh Agricultural University, Jamkhambhalia, Gujarat during kharif-2013 to 2018. The experiment comprising of 12 treatments with three replications laid out in randomized block design. The pooled results revealed that weed free (HW and IC at 15,30,45 and 60 DAS) treatment recorded significantly higher pod yield (2115 kg/ha), haulm yield (4919 kg/ha), maximum weed control efficiency (74.21%) and lowest dry weight of weed (492 kg/ha) with maximum net return (78857 Rs/ha)and BCR (2.93). However, integrated weed management practicesi.e.post emergence application of Quizalofop-ethyl @ 40 g/ha at 20 days after sowing followed by one hand weeding and one interculturing and pre- emergence application of Oxyfluorfen @ 0.24 kg/ha followed by one hand weeding and one interculturing at 40 days after sowing also recorded higher weed control efficiency, yield attributes, pod yield and haulm yield compared to other treatments.
