Effect of Integrated weed managementpractices in Chickpea

A field experiment was conducted at Research Farm of College of Agriculture, Tikamgarh (M.P.) during Rabi season of 2015-16 to evaluate the efficacy of different weed management practices in chickpea.The experiment was laid out in randomized block design with ten treatments. The treatments comprised of pre emergence pendimethalin @ 1.0 kg a.i./ha, pendimethalin + hand weeding at 30 DAS, pendimethalin + hand hoeing at 30 DAS, alachlor @ 1.0 kg a.i./ha, alachlor + hand weeding at 30 DAS, alachlor + hand hoeing at 30 DAS, straw mulch, weed mulch, weedy check and hand weeding twice at 20 and 40 DAS.The results revealed that hand weeding twice was most effective and recorded minimum weed density and weed dry weight followed by pendimethalin at 1.0 kg a.i./ha + hand weeding and pendimethalin at 1.0 kg a.i./ha + hand hoeing. Two hand weeding at 20 & 40 DAS recorded the highest yield (2381 kg/ha) among all the treatments followed by pendimethalin @ 1.0 kg a.i./ha + hand weeding at 30 DAS (2.07t/ha). Pre-emergence application of pendimethalin @ 1.0 kg a.i./ha and alachlor 1.0 kg a.i./ha produced significantly higher seed yield over straw mulch and weed mulch. The highest net monetary return obtained with two hand weedings followed by pendimethalin + hand weeding and pendimethalin + hand hoeing.
