Results reveal that the rice transplanted with rice variety SKL-3-1-41-8-33-15 recorded significantly higher yield attributes resulting into significantly more grain and straw yield over Sakoli-6. Significantly higher values of nitrogen, phosphorus and Potassium content and subsequently higher uptake were recorded by rice variety SKL-3-1-41-8-33-15 as compared to Sakoli-6. The available nitrogen, phosphorus and potassium status in the soil after harvest of rice was significantly higher in the field of rice variety Sakoli-6 followed by SKL-3-1-41-8-33-15. All the growth parameters, yield contributing characters, grain and straw yield, N, P and K content and uptake were not influenced significantly by different spacing i.e 20 × 20 and 20 × 15 cm. Also availability of N, P and K in the soil after harvest of rice was not influenced significantly by different levels of spacing. Application of 125% RDF recorded significantly higher values of growth and yield contributing characters resulting into significantly more grain and straw yield than rest of the fertilizer levels. N, P and K content and uptake both in the grain and straw of rice were significantly higher under application of 125% RDF followed by application of 100 and 75% RDF in the descending order of significance, Similarly the values of available N, P and K were significantly higher under the treatment of application of 125% RDF than rest of the fertilizer levels.
