Nutrient management for higher rice productivity under different establishment methods


Author(s): G Senthil Kumar

Abstract: A field experiment was conducted during Kharif, 2017 and 2018 at Department of Rice, Tamil Nadu Agricultural University, Coimbatore, to study the nutrient management for higher productivity in different rice establishment methods. Experimental trial was conducted in split plot design with three replications. In main plot, different rice establishment methods viz., M1: Machine transplanting method, M2: Conventional method, M3: System of Rice Intensification (SRI) method; where as in sub-plot, the nutrient management viz., S1: 100 % of recommended inorganic fertilizer (120:60:40 kg NPK/ha), S2: 75 % inorganic + 25 % organic (equivalent of N dose), S3: 150 % RDF (180:90:60 kg NPK/ha), S4: LCC based N application, S5: Location specific fertilizer management (150:50:50 kg NPK/ha). Based on the two years of study, the results revealed that among the different methods of planting and nutrient sources, SRI method of planting with LCC based N application recorded higher grain yield (6114 kg/ha) which was followed by machine transplanting method. The net return (Rs.55,882/-) and BCR (2.54) was higher under SRI method with LCC based N application when compared to other methods.
