Integrated weed management, Leaf area index, Crop growth rate, Productivity, Upland rice

A field experiment was conducted during kharif seasons of 2007 and 2008 at the Birsa Agricultural University farm, Ranchi on sandy loam soil to study the effect of integrated weed management on growth and productivity of direct seeded upland rainfed rice. Results showed that Sesbania intercropped and incorporated at 4 weeks after sowing + pendimethalin 1kg/ha recorded higher leaf area index, crop growth rate, effective tillers (124/m2), maximum grains/panicle (77) and bolder 1000-grain (24.3 g). The treatment produced higher grain yield (2091 kg/ha) and grain production rate (66.0 kg/ha/day) of direct seeded upland rice in comparison to other integrated weed management treatments.
