The same also produced grain yield 4.44 t ha~(-1) which is 55.79 % higher than Khandagiri with harvest index (47.06 %). The variety gave higher net return 32720.40 ha~(-1)with a benefit- cost ratio 2.00 and monetary productivity ' 582.53 ha~(-1)day~(-1) as compared to farmers practice and thus the existing variety Khandagiri can be replaced by Satyabhama for higher productivity and income.
