Abstract: A field investigation was carried out during June-September, 2016 and 2017 at College Farm, Agricultural College, Aswaraopet, Bhadradri Kothagudem Dist of Telangana State of India in sandy clay loam soil to evaluate the economic performance of semi dry rice under integrated nutrient and weed management practices. Three nutrient treatments as main plots{100% RDF, 75% RDF + 25% N through vermicompost and 75% RDF + 25% N through FYM} and four weed management practices {S
1: Control, S
2: Bispyribac sodium 10 SC 25 g ha
-1 (PE) fb HW @ 20, 40 DAS, S
3: Bispyribac sodium 10 SC 25 g ha
-1 (Early PoE) fb (Fenoxaprop-p-ethyl @ 62.5 g a.i ha
-1 + 2,4 – D 80 WP 0.5 kg a.i ha
-1) at 35 - 40 DAS and S
4: Bispyribac sodium 10 SC 25 g ha
-1 (PE) fb (Pyrazosulfuron ethyl 10 WP 25 g ha
-1 + 2, 4-D 80 WP 0.5 kg a.i ha
-1) + HW @ 50 DAS}were imposed as sub plot treatments in split plot design replicated thrice. Significantly, enhanced grain & straw yield and economic returns were noticed with 75% RDF + 25% N through vermicompost. Among weed management practices, Bispyribac sodium 10 SC 25 g ha
-1 (PE) fb (Pyrazosulfuron ethyl 10 WP 25 g ha
-1 + 2, 4-D 80 WP 0.5 kg a.i ha
-1) + HW @ 50 DAS} registered significantly higher yield and economic returns. Interaction effect of nutrient and weed management practices on grain and straw yield and economics was found to be significant.
