Effect of integrated nutrient management practices on growth attributes of transplanted rice

Abstract

An experiment was conducted at experimental research farm, Rampur, Doon PG college of Agriculture and Allied Sciences, Rampur, Selaqui, Dehradun “Effect of Integrated Nutrient Management Practices on Yield Attributes of Transplanted Rice (Oryza Sativa L.)” during kharif season of 2016.Twelve treatments viz., Control (T0), FYM @ 12.5 t ha-1 + 100% RDF, FYM @ 12.5 t ha-1 + 75% RDF, GM @ 6.25 t ha-1 + 100% RDF, GM @ 6.25 t ha-1 + 75% RDF, FYM @ 12.5 t ha-1 + Biofertilizer + 100% RDF, FYM + @ 12.5 t ha-1 + Biofertilizer + 75% RDF, FYM @ 12.5 t ha-1 + Biofertilizer, GM @ 6.25 t ha-1 + Biofertilizer + 100% RDF, GM @ 6.25 t ha-1 + Biofertilizer + 75% RDF, GM @ 6.25 t ha-1 + Biofertilizer, FYM @ 12.5 t ha-1 + GM @ 6.25 t ha-1 conducted in a randomized block design (RBD) with three replications. Rice variety “PS-5” was used as test crop. The soil of experimental plot was silt clay loam in texture, medium organic carbon and available nitrogen, high in available Phosphorus and rich in Potassium status. The results of the experiment indicated that maximum value of growth attributes viz., plant height, no of tillers and dry matter accumulation were conspicuously increased with the application of GM @ 6.25 t ha-1 + Biofertilizer + 100% RDF (T8) and was superior over rest of the treatments but at par with GM @ 6.25 t ha-1 + Biofertilizer + 75% RDF (T9) and FYM @ 12.5 t ha-1 + Biofertilizer + 100% RDF (T5). However the lowest growth attributes were recorded with the treatments Control (T0), FYM @ 12.5 t ha1 (T11).Based on the results, it can be concluded that higher grain yields and net profit from Transplanted Rice crop can be obtained with the application of GM @ 6.25 t ha-1 + Biofertilizer + 100% RDF (T8).
