Response of Nutrient and Weed Management Techniques on Semi Dry Rice Growth, Yield Parameters and Yield in Telangana

Abstract

At College Farm, Agricultural College, Aswaraopet, Bhadradri Kothagudem District, a field experiment was conducted on sandy clay loam soil in semi-dry rice during the kharif seasons of 2016 and 2017. The experiment was set up in a split plot design with three replications of each nutrient (chemical fertilizer alone and the combination of fertilizers with organic manures) and four weed management practices (Control, combination of pre/early post-emergence and post-emergence herbicides, along with hand weeding). Results of pooled analysis revealed that 75% RDF +25% N through vermicompost and Bispyribac sodium 10 SC@25 g ha-1 (PE) fb (Pyrazosulfuron ethy l10WP@25gha-1+2,4-D80WP@0.5kg a.i ha-1) + HW@ 50 DAS recorded significantly highest dry matter production, no. of panicles m-2, no. of filled grains panicle1, test weight, grain and straw yield.
