Abstract

A field experiment was conducted during Kharif season 2015 at Instructional cum Research Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur. The experiment was laid out in split-split plot design with three P and K application as main plot, two brown manuring as sub plot and four weed management practices as sub-sub plot with three replications. The results revealed that significantly highest panicle length, panicle weight, test weight, grain yield, straw yield, harvest index and N, P, K uptake were recorded under treatment 50 % P and K at sowing and 50 % P and K at 30-35 DAS. Brown manuring produced significantly highest panicle length, maximum panicle weight, test weight, grain yield, straw yield, harvest index, N, P and K uptake as compare to without brown manuring. In case of weed management, pre-emergence herbicide pyrazosulfuron 20 g ha-1 followed by biasi followed by hand weeding recorded maximum panicle length, panicle weight and test weight, grain yield, straw yield, harvest index and N, P, K uptake kg ha-1 over other weed management practices which was found at par with biasi operation followed by hand weeding and pre emergence herbicide pyrazosulfuron 20 g ha-1 followed by post emergence herbicide bispyribac-Na 20 g ha-1. Interaction amongst the P and K application, brown manuring and weed management practices found significant for grain yield and non-significant difference was recorded in other yield parameters and N, P, K uptake of rice. Significantly highest grain yield was recorded with 50 % P and K at sowing and 50 % P and K at 30-35 DAS, brown manuring and pre emergence herbicide pyrazosulfuron 20 g ha -1 followed by biasi followed by hand weeding
