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 than Sakoli-6. The highest net returns of 76715 Rs. ha^-1 with B:C ratio of 2.27 were obtained by rice variety SKL-3-1-41-8-33-15 followed by Sakoli-6 (50800 Rs. ha^-1) with B:C ratio 1.84 during the year of field experiment. The net monitory returns and B:C ratio were non-significant but higher for spacing 20 × 15 cm (66646 Rs. ha^-1) with B:C ratio 2.09 which was higher than 20 × 20 cm. Application of 125% RDF recorded significantly higher values of yield contributing characters resulting into significantly more grain and straw yield than rest of the fertilizer levels. Application of 125% RDF recorded highest net returns (67236 Rs. ha^-1) followed by application of 100% RDF (65010 Rs. ha^-1) and 75% RDF (46322 Rs. ha^-1) in the descending order. Whereas, B:C ratio of application of 125% (2.02) and 100% RDF (2.01) was at par with each other.

The economics of treatment combinations reveal that the highest net returns were obtained when the rice crop was transplanted with variety SKL-3-1-41-8-33-15 at spacing 20 cm x 15 cm fertilized with 125% RDF which was closely followed with variety SKL-3-1-41-8-33-15 with 20 x 15 cm spacing and fertilized with 100% RDF. While, the B: C ratio was recorded higher with rice variety SKL-3-1-41-8-33-15 at 20 × 15 cm spacing and application of 125% RDF.
