Abstract
A field experiment was conducted at Agronomy farm, S.K.N. College of Agriculture, Jobner, Jaipur (Rajasthan) during kharif season of 2018 to study the effect of weed management practices on weed studies, grain yield and nutrient depletion in clusterbean. The experiment comprising of 9 treatments i.e. Weedy check, One hand weeding at 25 DAS, Two hand weedings at 25 and 45 DAS, Pendimethalin @ 750 g a.i./ha (PE), Imazethapyr @ 75 g a.i./ha (PoE), Quizalofop-p- ethyl@ 37.5 g a.i./ha (PoE), Pendimethalin @ 750 g a.i./ha (PE) + Quizalofop-p-ethyl@ 37.5 g a.i./ha (PoE), Pendimethalin @ 750 g a.i./ha (PE) + Imazethapyr @ 75 g a.i./ha (PoE), Pendimethalin 30 EC + Imazethapyr 2 EC (RM) @ 750 g a.i./ha as pre- emergence was laid out in randomized block design and replicated thrice. The results showed that weed management practices markedly reduced crop-weed competition. Both hand weedings at 25 and 45 DAS and pendimethalin @ 750 g a.i./ha (PE) + imazethapyr @ 75 g a.i./ha (PoE) treatments were found significantly superior in reducing weed density, dry weight and nutrient depletion by weeds as well as higher weed control efficiency than weedy check and all other single herbicide applied treatments viz. Pendimethalin @ 750 g a.i./ha (PE), Imazethapyr @ 75 g a.i./ha (PoE), Quizalofop-p-ethyl @ 37.5 g a.i./ha (PoE) and one hand weeding at 25 DAS. The grain yield was significantly higher under the treatment two hand weedings at 25 and 45 DAS over weedy check and superior to all single herbicide applied treatments and one hand weeding at 25 DAS, but it was at par with treatments pendimethalin @ 750 g a.i./ha (PE) + imazethapyr @ 75 g a.i./ha (PoE), pendimethalin (PE) @ 750 g a.i./ha + quizalofop-p-ethyl @ 37.5 g a.i./ha (PoE), pendimethalin 30 EC + imazethapyr 2 EC (RM) @ 750 g a.i./ha as (PE).
