Abstract
Field experiments were conducted during Kharif 2012-13 and 2013–14 at the Research farm of Rajendra Agricultural University Bihar, Pusa to find out effective and economical approaches for weed management in turmeric. The grassy weeds present in the experimental field were Cynodon dactylon, Echinocloa colona and Dactyloctenium aegyptium. Cyperus rotundus was only sedge and Chenopodium album, Cannabis sativa, Parthenium hysterophorus, Phyllanthus niruri and Caesulia auxillaris were the broad-leaved weeds. The lowest weed count, weed dry weight and the highest number of tillers per plant, number of leaves per plant and rhizome yield of turmeric were recorded by the weed free (hand weeding at 25 and 45 DAS). The highest rhizome yield (52.05 t/ha) was recorded under weed free which was statistically at par with atrazine 0.75 kg/ha fb fenoxaprop 67 g/ha+ metsulfuron 4 g/ha (50.65 t/ha). The highest weed control efficiency (84.62%) was recorded under the treatment weed free which was closely followed by atrazine 0.75 kg/ha fb fenoxaprop 67 g/ha+ metsulfuron 4 g/ha (78.9%) and pendimethalin 1.0 kg/ha fb fenoxaprop 67 g/ha + metsulfuron 4 g/ha (78.6%). The highest B: C ratio was recorded with application of atrazine 0.75 kg/ha fb fenoxaprop at 67 g/ha + metsulfuron 4 g/ha, which was statistically at par with weed free, pendimethalin 1.0 kg/ha fb fenoxaprop at 67 g/ha + metsulfuron 4 g/ha and metribuzin 0.7 kg/ha fb fenoxaprop at 67 g/ha + metsulfuron 4g/ha.
