Title: Bio- efficacy of Different Herbicides in Broad Spectrum Weed Management for Chickpea
Abstract: A field experiment was conducted during rabi seasons of 2014-15 and 2015-16 at research farm of TCA, Dholi, Muzzafarpur a campus of Dr Rajendra Prasad Central Agricultural University, Pusa, Samastipur, Bihar (India) to evaluate the bio- efficacy of different herbicides in broad spectrum weed management for chickpea. Ten treatments were tested in randomized block design with three replications. Among the herbicides pendimethalin CS formulation (1 kg/ha), PE + One hoeing 35 DAS recorded significantly higher seed yield (1348.50 kg/ha), straw yield(1600.33 kg/ha)lower weed dry weight (1.34g/m2), lower weed index (5.91 %), higher weed control efficiency (73.28%) and more added returns (Rs. 64280/ha) than all other herbicidal treatments. Present investigation revealed that pendimethalin CS formulation (1 kg/ha), PE + One hoeing 35 DAS could be used effectively as an alternative for controlling most of the weeds and obtaining optimum seed yield of chickpea during rabi season in Bihar.
