Effect of integrated nutrient management on yield and yield attributes of rice (Oryza sativa L.)

Abstract

The present study conducted to evaluate the suitable proportion of organic manures and inorganic fertilizers along with biofertilizer to maximize growth and dry matter accumulation of rice on alkaline soils of Uttar Pradesh, India. The experiment consisting twelve treatments viz., T1 (control), T2 (75% RDF), T3 (100% RDF), T4 (125% RDF), T5 (100% RDF + FYM 6 t/ha), T6 (100% RDF V. C.3 t/ha), T7 (100% RDF + BGA @ 10 kg/ha), T8 (100% RDF + neem cake 6 q/ha), T9 (75% RDF + FYM 6 t/ha) k T10 (75% RDF + V.C.3 t/ha), T11 (75% RDF + BGA 10 kg/ha) and T12 (75% RDF + neem cake 6 q/ha) were tested in Randomized Block replicated as thrice. The maximum yield and yield attributes of rice crop was recorded under nutrient management module of 100% RDF + 3 tonne vermi compost closely followed by 100% RDF + 6 tonne FYM. Significantly higher grain and straw yield was recorded under treatment having 100% RDF + 3 tonne vermi compost over all the treatment except treatment T4, T5, T7 and T8 T12 which was recorded at par.
