Effect of integrated weed management practices in chickpea (original) (raw)

A field experiment was conducted at Agriculture Research Station, Annigeri, University of Agricultural Sciences, Dharwad during Rabi season of 2015-16 to find out most suitable integrated weed management practices for control of weeds in chickpea under rainfed condition. Among integrated weed management practices, application of pendimethalin @ 1.0 kg a.i ha-1 as pre-emergence followed by imazethapyr @ 75 g a.i ha-1 at 20 DAS as postemergence followed by hoeing at 40 DAS (T10) recorded significantly the lowest weed density (8.09, 6.14 and 3.78 m-2) at 20 DAS, 40 DAS and at harvest, respectively, which resulted in lowest dry weight of weeds (3.58, 3.34 and 1.81 g m-2) at 20 DAS, 40 DAS and at harvest, respectively and highest weed control efficiency (70.56 and 92.78 %) at 40 DAS and at harvest, respectively. Further, this treatment also recorded significantly the higher plant height (32.83 cm), primary branches (3.20 plant-1), number of pods (34.13 plant-1), Seed weight (8.35g plant-1), B:C ratio (1.44) and seed yield (745 kg ha-1).
