Effect of Weed Management Practices and Establishment Methods on Growth, Productivity and Economics of Rice
Journal Title: International Journal of Current Microbiology and Applied Sciences (IJCMAS) - Year 2017, Vol 6, Issue 3
Abstract
A field experiment was conducted at N.E. Borlaug Crop Research Centre of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, U.S. Nagar (Uttarakhand) during Kharif seasons of 2010-11 and 2011-12 to study the effect of crop establishment methods and weed management practices on growth and productivity of rice. Four crop establishment method viz. system of rice intensification (SRI), transplanted rice (TPR), direct seeded rice (DSR-dry seeded) and wet seeded rice (WSR- sprouted) and four weed management practices viz. pyrazosulfuron-ethyl (3 DAS/DAT) + mechanical weeding (at 40 DAS/DAT), cono-weeder (twice- at 20 and 40 DAS/DAT), hand-weeding (twice- at 20 and 40 DAS/DAT) and weedy check were tested in strip plot design with three replications. Maximum shoot dry matter, higher number of panicles, grains per panicle, longer panicle length, test weight, grain yield and net return was recorded in hand weeding (20 and 40 DAS/DAT) than that of other weed management practices. Among the rice establishment methods, SRI method exhibited maximum grains per panicle, longer panicle length, test weigh, grain yield and harvest index and net return.
