Effect of organic and inorganic sources of nutrients on rice crop

An experiment was conducted for two consecutive years (2011–2012 and 2012–2013) on fine texture soils of Agricultural college farm, Bapatla. The experiment was laid out in a randomized block design in wet season with four treatments and five replications. The treatments consisted of M₁ (recommended dose of fertilizers (RDF)-Control), M₂(10t farmyard yard manure (FYM) ha⁻¹ + RDF), M₃(1.5t vermicompost ha⁻¹ + RDF), M₄ (Green manuring + RDF). Data collected on biometric observations (plant height, number of tillers, dry matter accumulation) and yield. The yield of crop was significantly increased with the application of 100%NPK in combination with FYM @10t ha⁻¹. However, it was at par with green manuring along with the application of 100% RDF (NPK). Thus, green manure in situ with Dhaincha may be used as an alternative organic source of nutrients to the FYM.
