Abstract:

A field experiment was conducted for two consecutive rainy seasons of 2011 and 2012 at G. B. Pant University of Agriculture and Technology, Pantnagar, U.S. Nagar (Uttarakhand) to evaluate the “Influence of various weed management approaches on weed dynamics in rice under different crop establishment methods”. The results revealed that the lowest density and dry matter of total weeds at 60 days after sowing/days after transplanting was obtained with transplanted rice. This treatment produced the highest number of panicles/m2 and rice grain yield (4145 and 3879 kg/ha). Among the weed management practices, application of bispyribac sodium 20 g/ha at 15 DAS/DAT followed by one hand weeding at 35 DAS/DAT recorded the minimum population and dry matter of total weeds and recorded the highest weed control efficiency which showed at par results with the application of bispyribac sodium 22.5 g/ha at 2-3 leaf stage of weeds followed by one HW at 35 DAS/DAT. This treatment produced the significantly higher number of panicles/m2, grains/panicle and grain yield.
