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.
