Abstract

A field experiment was conducted during the rainy (kharif) season of 2002, 2003 and 2004 to study integrated weed management in rainfed kodo millet (Paspalum scrobiculatum L.). Application of isoproturon (0.50 kg ai/ha) as pre-emergence + one intercultivation (20 days after sowing) + one hand-weeding (40 DAS) appreciably lowered the weed population (16.7/m2) and dry weight of weeds (56 g/m2). It increased the weed-control efficiency by 50.21 per cent compared with pre-emergence application of isoproturon @ 0.50 kg/ha. It was followed by intercultivation (20 DAS) and hand-weeding (40 DAS), which gave the highest grain yield (18.42 q/ha) and fetched higher net monitory return (Rs 5,698/ha) in all weed-control measures.
