Abstract: A field experiment was conducted on weed management practices in direct sown finger millet at Agronomical farm, Birsa Agricultural University, Ranchi during kharif season of 2016. The weeds were randomly sampled from the fields of finger millet crop using a quadrate of size 0.25 m x 0.25 m randomly thrown at 3 different sites. The data were recorded on weed density, relative weed density, weed frequency, relative weed frequency and importance value index of weeds. The experimental data showed that total 19 plant weed species, belonging to 12 families were collected and identified from the study area. The major weeds found, infesting the experimental field were Commelina bengalensis (L.) - 14.13%, Echinocloa crusgalli (L.) - 11.63%, Cyperus rotundus (L.) - 9.97%, Ageratum conyzoides - 9.14%, Commelina nodifolia (L.) - 6.65%, Oldenlandia corymbosa - 6.65% and Dactyloctenium aegyptium (L.) - 5.68%. Broad-leaf weed species were dominant throughout the growing period of crop. Grassy, broad- leaf and sedges accounted for 24.37%, 60.40% and 15.23%, respectively of respective weed flora of the experimental field. Therefore, integration of chemical, cultural and mechanical methods might be an answer to achieve greater weed control efficiency, which in turn may increase over all benefit of finger milletcultivation.
