dc.description.abstract |
The experiment comprising of twelve treatments was laid out in a randomized block design with three
replications. Prominent weeds were Echinochloa colona and Digitaria sanguinalis among the grasses;
Cyperus iria, among the sedges and Spilanthes acmella and Ludwigia parviflora among the broadleaved
weeds throughout the cropping period. Fenoxaprop-p-ethyl at 60 g/ha + metsulfuron-methyl +
chlorimuron-ethyl at 4 g/ha at 25 DAT effectively controlled the grasses, broad-leaved and sedges at 50
DAT which was statistically at par with the azimsulfuron at 40 g/ha at 20 DAT. The loss of grain yield of
rice due to weed infestation was to the tune of 35-38%. Lower values of weed density, total weed dry
weight and higher values of weed control efficiency, yield and net return of rice were registered with
combined application of fenoxaprop-p-ethyl at 60 g/ha + metsulfuron-methyl + chlorimuron-ethyl at 4 g/
ha at 25 DAT and was followed by sole application azimsulfuron at 40 g/ha at 20 DAT. These treatments
may be recommended for managing composite weed flora and obtaining higher yield and net return of
transplanted Kharif (wet) rice in the lateritic belt of West Bengal, India. |
