A field experiment was conducted during the winter season of 1993–94 to 1995–96 at Pulse Research Station, R.A.K. College of Agriculture, Sehore, Madhya Pradesh, to study the effect of weed-management practices on chickpea (Cicer arietinum L.) under late-sown condition. Two hand-weedings at 30 and 45 days after sowing (DAS) (weed-free) completely controlled the weeds. Significantly lowest weed dry matter and highest weed-control efficiency were observed when 1 hand-weeding was done at 45 DAS. This treatment was followed by integration of 1 hand-weeding at 45 DAS with pre-emergence application of pendimethalin 0.75 kg/ha in reducing weed dry matter and in increasing the weed-control efficiency. Significantly higher grain yield (1, 723 kg/ha) was recorded in weed-free plots. Among the.weed-control treatments, pendimethalin 0.75 kg/ha coupled with 1 hand-weeding at 45 DAS recorded higher grain yield (1576 kg/ha).
