ABSTRACT

A field experiment was carried out during kharif 2010 at the Instructional-cum-Research Farm, IGKV, Raipur (C.G.). The soil of the experimental field was clay in texture. The soil was neutral in pH and head low nitrogen, medium phosphorus and high potassium content. The experiment was laid out in randomized block design with three replications. Results revealed that the minimum weed growth rate, density and dry matter production of weeds and the highest weed control efficiency were recorded with pre-emergence application of imazethapyr 100 g/ha fb one hoeing at 20 DAS followed by pendimethalin 1000 g/ha supplemented with one hand weeding at 20 DAS. The highest seed yield and harvest index were obtained with application of imazethapyr 100 g/ha fb one hoeing at 20 DAS, while the highest stover yield was obtained with application of pendimethalin 1000 g/ha fb hand weeding at 20 DAS. The highest weed index was recorded under weedy check.
