The nitrogen, phsophorus and potassium cont~nt and uptake was higher at NlOOP50 kg/ha
application of fertilizers. The highest net monetary return of Rs. 15692 was obtained also at
NlOOP50 kgiha 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.
