The nitrogen, phsophorus and potassium content and uptake was higher at N100P50 kg/ha application of fertilizers. The highest net monetary return of Rs. 15692 was obtained also at N100P50 kg/ha fertility level. Amongst the genotypes, hybrids were efficient in accumulating nitrogen, phosphorus and potassium compared to conventional varieties. The hybrid PJH-58 recorded highest total uptake of nitrogen, phosphorus and potassium followed by PJH-55. The varieties SPV-1025 recorded lowest uptake of NPK. The benefit: cost ratio was higher statistically in hybrids than varieties and PJH-58 was having highest economic desirability and feasibility in terai conditions (Rs. 3.19) compared to other hybrids and varieties. The grail) as well as stover yield followed similar trend as observed in nutrients uptake and in net returns.
