Abstract
Field experiment was conducted during Kharif 2016 at College Farm, College of Agriculture, Rajendranagar, Hyderabad to identify the effect of different crop establishment methods and weed management options in rice. The weed spectrum of the experimental field consisted of all the three groups of weeds viz., Cynodon dactylon, Dinebra retroflexa, Echinochloa crusgalli and Paspalum distichumamong grasses; Cyperus difformis, Cyperus iria and Scirpus spp., among sedges and Eclipta alba, Ammania baccifera, Trianthema portulacastrum, Euphorbia geniculata, Euphorbia hirta and Amaranthus viridis among BLWs. Among different establishment methods transplanted rice recorded lowest weed density, weed dry weight and higher weed control efficiency. Among weed management practices, application of pretilachlor as PE fb hand weeding twice at 20 and 40 DAS/T recorded the lowest weed density, dry matter and higher weed control efficiency.
