Abstract: An experiment was conducted during the growing seasons of 2019-20 to know the response of hybrid napier to combinations of major (150:50:40 and 225:75:60 kg NPK ha-1) and micro (0, 25 kg ha-1 ZnSO4 and FeSO4 ha-1 singly and in combination) nutrients in the semiarid tropics under irrigation. Results revealed that application of 225:75:60 kg NPK ha-1 along with 25 kg ZnSO4 ha-1 and 25 kg FeSO4 ha-1 recorded significantly higher green fodder yield (70.09, 80.00, 75.53, 80.36, 75.81, 62.00 and 57.00 t ha-1, respectively at 1st to 7th cut), net returns (₹ 29272, 85535, 77671, 83467, 78007, 63935 and 57935/-, respectively at 1st to 7th cut) and benefit cost ratio (9.17, 6.99, 7.44, 7.02, 7.11 and 6.54 benefit cost ratio at 2nd to 7th cut, respectively) due better growth compared to recommenced fertilization of 150:50:40 kg NPK ha-1 (52.00, 58.60, 57.00, 59.85, 52.59, 48.00, and 43.00 t ha-1 green fodder yield, ₹ 21540, 60428, 56008, 59428, 50716, 47708, 41708/- net returns at 1st to 7th cut, respectively and 7.11, 5.52, 5.80, 5.09, 5.82 and 5.22 B:C at 2nd to 7th cut, respectively).
