The study was carried out during the year 2016-17 to examine different weed management techniques in sugarcane (Saccharum officinarum L.). The experiment was laid out at Sugarcane Section, Agriculture Research Institute, Tandojam in a three replications RCBD with (8 m x 3 m) 24m2 size of plot. In current investigation the study area was made up of four weed species were recorded which included Chaff-flower, Green amaranth, Creeping thistle and Lamb's quarters. The above record of the weed flora was maintained sowing of sugarcane. The sugarcane crop treated with hand hoeing thrice resulted in 94.27 m-2 weed density, 39.33% weed reduction, 192.00 cm cane length, 2.05 cm cane girth, 6.13 tillers stool-1, 14.45 kg weight of 10 canes, 58.13 t ha-1 cane yield, 20.33% brix and 10.17% sugar recovery. The crop treated with weedy check produced 155.45 m-2 weed density, 0.00% weed reduction, 161.67 cm cane length, 1.73 cm cane girth, 2.98 tillers stool-1, 6.68 kg weight of 10 canes, 27.22 t ha-1 cane yield, 18.94% brix and 9.47% sugar recovery. It was concluded that the crop treated with Buctril M @ 3.75 kg ha-1 resulted in highest cane height, girth, density and yield.
