A field experiments was conducted during Kharif seasons 2007 at Junagadh Agricultural University, Junagadh, Gujarat to study the effect of weed management practices on cowpea under rainfed conditions. It was found that single application of herbicide or cultural practices (1 HW + 1 IC) at 20-25 DAS not sufficient to control weed in cowpea and significantly yield loss 20-25% recorded, which is just half of around 45% yield loss in case no weed control measure followed. Application of (pendimethalin at 0.5 kg ha-1 as PRE + 1 HW + 1 IC at 25-30 DAS), (quizalofop- ethyl at 0.04 kg ha-1 as POST 20-25 DAS + 1 HW + 1 IC at 40-45 DAS) and (imazethapyr at 0.075 kg ha-1 as POST 20-25 DAS + 1 HW + 1 IC at 40-45 DAS) gave yield statistically at par with weed free plot. So integrated weed management is better option and cowpea farmer can replace 20-25 DAS (1 HW + 1 IC) cultural practices with suitable herbicide to get same yield.
