The present investigation was carried out during kharif season of 2006 at the Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi. The experiment was laid out in a Randomized Block Design (RBD) with 10 treatments viz. T1 Â (Anilofos 30% GR with emulsifier @ 300 g ai/ha), T2 Â (Anilofos 30% GR with emulsifier @ 450 g ai/ha), T3 Â (Anilofos 30% GR with emulsifier @ 600 g ai/ha), T4 Â (Anilofos 30% GR w/o emulsifier @ 300 g ai/ha), T5 Â (Anilofos 30% GR w/o emulsifier @ 450 g ai/ha), T6 Â (Anilofos 30% GR w/o emulsifier @ 600 g ai/ha), T7 Â (Anilofos 30% EC @ 300 g ai/ha), T8 Â (Anilofos 30% EC @ 450 g ai/ha), T9 Â (Weedy check) and T10 (Weed free) in three replication. The results revealed that among the herbicides, application of anilofos 600 g GR with emulsifier ha-1 (T3 ) recorded significantly minimum density of grasses, sedges and broad leaved weeds, and higher no. of effective tillers, maximum panicle length and weight, 1, 000 grain weight, grain and straw yields, harvest index, nutrient content and minimum weed index.
