Abstract

A field experiment was carried out during rainy (Kharif) season in 2012-2013 at Agricultural Research Farm, IAS, BHU-Varanasi, to evaluate the various crop establishment method and Integrated Nutrient Management on growth, yield and economics of rice (Oryza sativa L.).The treatments were comprised three crop establishment methods viz. SRI (T1), Wetland transplanting (T2) and farmer’s practice (T3) and five nutrient management sources viz.100% RDF (N1), 100 % RDF + Zinc ( 5 kg Zn ha-1 from ZnSO4.7H2O) (N2), 100 % RDF + 2.5 t ha-1 Vermicompost (N3), 100 % RDF +5 kg Zinc + 2.5 t ha-1 Vermicompost (N4), and 100 % RDF + 5 t ha-1 FYM (N5) in split plot design with three replications and fifteen treatment. Significant effects of various crop establishment and integrated nutrient management were observed on rice during experiment in comparision with 100% RDF. With crop establishment methods, grain and straw yields of rice were 4.28 t ha-1 and 7.23 t ha-1 under SRI, which were 13.24 and 4.53% higher as compared to farmer’s practice. The effect of application of nutrient management sources (100 % RDF +5 kg Zinc + 2.5 t ha-1 Vermicompost) resulted in the highest rice grain (4.37) and 7.32 (t ha-1) with respect to 100% RDF. Highest gross returns (62599.56 ¹ ha-1) were examined with 100 % RDF +5 kg Zinc + 2.5 t ha-1 Vermicompost as compared to rest of the treatments but in case of net returns and output/input ratio, the net returns (23503.40 ¹ ha-1) and output/input ratio (1.69) were found higher with 100% RDF+5 kg Zn ha-1 as compared to rest of the treatments.
