Abstract:
A field experiment entitled “Effect of fertilizer levels, spacing on yield and nutrient uptake of Paddy (Oryza sativa L.)” was conducted at Agriculture Research Station, Sakoli. The experiment was laid out in split plot design with three replication. The main plot treatments comprised of two varieties (SKL-3-1-41-8-33-15 and Sakoli-6) and sub-plot treatment comprised of combinations two levels of spacing (20 × 20 and 20 × 15 cm) and three levels of fertilizer (75%, 100% and 125% RDF).
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.
