Influence of FYM, poultry manure, neem cake and fertilizer on growth, yield of rice (Oryza sativa L.), soil nutrient status and microbial population under system of rice intensification

The experiment was laid out in Randomized Complete Block Design (RCBD) with ten treatments replicated thrice. The treatments consisted of 100%, 75%, 50% & 25% Recommended Doses of Nutrients (RDN) through chemical fertilizers and 25%, 37.5% & 50% RDN through organic sources like Farm yard manure, Poultry manure and Neem cake. Application of Recommended Dose of Nutrients (120:60:40kg N:P:K/ha) along with 10 tonnes of FYM/ha recorded significantly higher plant height (88.2 cm), more No. of Tillers/hill (38.7), number of filled grains per panicle (154.3), Panicle length (21.07 cm), and grain yield (52.6 q/ha).
