Effect of different pre and post-emergent application of herbicides on the growth and yield of Indian mustard (Brassica juncea L.)

Abstract

This study was carried out to evaluate the growth and yield of Indian mustard was influenced by application of different pre and post emergent herbicides at the research farm of School of Agricultural Sciences, GD Goenka University, Gurugram (Haryana) during rabi season of 2019-20. Seven treatments comprising weedy check, weed free check, Pendimethalin @ 1.0 kg ha-1 as pre-emergence (PE), Oxyfluorfen @ 0.15 kg ha-1 as pre-emergence, Quizalofop @ 0.06 kg ha-1 at 25-30 Days after Sowing (DAS), Isoproturon @ 1.0 kg ha-1 as pre-emergence and Isoproturon @ 1.0 kg ha-1 at 30 DAS were tested in randomized block design with three replications. Highest seed yield was noticed in weed free treatment with the value of 1957 kg ha-1. Among the herbicidal treatments, Pendimethalin @ 1.0 kg ha-1 (PE) recorded maximum seed yield of 1742 kg ha-1 over other.
