Weed infestation is serious problem in cultivation of finger millet under upland situation. Two to three flushes of weeds during vegetative phase are common during rains. An experiment was conducted on finger millet during kharif season of 2005, 2006 and 2007 at S.G. College of Agriculture and Research Station, Jagdalpur. The experiment was laid out in randomized block design with twelve treatments. Weed population and dry matter accumulation by weeds was significantly varied due to weed control treatments in three years of experimentation. The maximum weed population of 120, 416 and 432 for broad leaf weeds and 916, 858 and 959 for narrow leaf weeds were found in weedy check in 2005, 2006 and 2007, respectively, while dry matter  of 696, 663 and 662 g/m for broad leaf weeds and 1271, 1134 and 514 g/m for narrow leaf weeds was recorded. The application of pre-emergence spray of isoproturon 0.5 Kg/ha + two hand intercultivation (20 and 40 DAS) gave significantly minimum weed population and dry matter accumulation. Pre-emergence spray of isoproturon 0.5 kg/ha + two intercultivations (T₈) produced maximum grain yield (1902, 1887 and 1880 kg/ha) after hand weeding
