A large-scale field trial was conducted at Agricultural Research Station (Paddy), Sirsi of the University of Agricultural Sciences, Sirsi, Karnataka, India, during 2004–15 on a fixed site, to study the effect of different organic farming practices on productivity of rice (Oryza sativa L.) under inorganic and integrated nutrient-management practices. The trial consisted of 5 treatments, viz. T1 , Organic [75% N through organic manures + 100% organic plant protection (PP) measures]; T2, organic [100% N through organic manure + 100% organic plant protection (PP) measures]; T3 , integrated nutrient management [50% N through organic manures + 50% RDF + integrated PP measures]; T4 , inorganic treatment [recommended dose of fertilizers (RDF) alone + inorganic PP measures]; and T5 , recommended practice (RDF + FYM 10 t/ha + integrated PP measures). The rice variety ‘Abilash’ was grown during the rainy (kharif) season with these treatments. At the end of 12th year, i.e. during 2015, the grain yield recorded in treatment T2 (6.418 t/ha) was the maximum and was found on a par with T5 (6.328 t/ha). How-ever, the straw yield was the maximum in T5 (7.577 t/ha), being at par with T2 (7.494 t/ha). The net returns realized were significantly highest with treatment T2 (`41,045/ha) compared to all the other treatments. The soil organic carbon (0.77%), available major (221.2, 22.0 and 67.0 kg/ha of N, P and K, respectively) and micro-nutrients (515.5, 100.8, 5.6 ppm of calcium, magnesium and zinc, respectively and 7.6 kg/ha of sulphur) were also higher with treatment T2 .
