Abstract:

A field experiment was conducted during 2008-09 and 2009-10 at G.B. Pant University of Agriculture & Technology, Pantnagar (Uttarakhand). The soil of the experimental field was clay loam texture, medium in organic carbon (0.66%), available phosphorus (27.5 kg P/ha) and potassium (243.5 kg K/ha) with pH 7.2. Experiment consisted of six treatments were laid out in randomized block design with four replications. In the experimental field Cyperus rotundus, Ehinochloa colona, Brachiaria reptans,Commelina benghalensis, Ipomoea spp. and Parthenium hysterophorus were major weeds in both the years. Beside these, Digitaria sanguinalis was also observed as major weed during 2009-10. Other weeds were Cleome viscosa, Corchorus acutangulus, Dactyloctenium aegyptium and phylanthus niruri. Lowest density as well as dry weight of total weeds were recorded under the treatment of three hoeing at 30, 60 and 90 days after harvesting (DAH) of main crop which was at par with per-emergence application of metribuzin 0.88 kg/ha followed by (fb) hoeing at 45 DAH fb 2,4-D 1.0 kg/ha at 90 DAH. The highest cane yield was recorded with the execution of three hoeings at 30, 60 and 90 DAH treatment which was closely fb metribuzin at 0.88 kg/ha at 3 DAH fb hoeing at 45 DAH fb 2,4-D 1.0 kg/ha at 90 DAH of main crop.
