Abstract

A field experiment was conducted during Rabi season of 2021-22 at Chamelti Agriculture Farm, Shoolini University of Biotechnology and Management Sciences Solan (H.P.). Results of the experimental field were revealed that treatment N4 was increased in seed, stover and biological yield to the tune of 12.66 and 25.20%, 9.48 and 21.5%, 10.18 and 22.36% as compared to N3 and N2, respectively. Besides S4 was exhibited 4.32 and 11.05%, 6.70 and 10.61% and 6.14 and 10.71% increase in seed yield, stover yield and biological yield, respectively as compared to S3 and S2. Treatments N4 and S4 were recorded maximum oil content and oil yield followed by N3 and S3. Treatment S4 was recorded to the tune of 0.24 and 20.45% more oil yield as compared to S3 and S2. The maximum gross returns, net returns and B:C ratio was recorded under treatments N4 and S4.
