Abstract:
A field experiment was conducted at Agricultural College, Aswaraopet, Bhadradri Kothagudem, Telangana during Kharif 2016 to evaluate the effect of nutrient and weed management under semi dry rice in Sandy clay loam soil. The experiment was laid out in a split plot design with three replications comprising of three nutrient and four weed management practices. Grain and straw yield and harvest index recorded was significantly higher in 75% RDF+25% N through Vermicompost and FYM over 100% RDF. Application of herbicides coupled with hand weeding recorded significantly superior grain and yield and harvest index compared to sole application of herbicides or control. Similar pattern of higher energy output, net energy, energy productivity, energy use efficiency was noticed with different nutrient and weed treatments. On contrary, energy intensity in physical and economic terms followed an opposite trend.
