SUMMARY
A field experiment was conducted during kharif of 2020, 2021 and 2022 at Veterinary College, Shivamogga to study the integrated nutrient management in hybrid napier cultivar CO-4. The experiment was laid out in a randomized complete block design with eight treatments comprisesT1: recommended package of practices, T2: 50 per cent N through inorganic fertilizer + 50 per cent N through FYM, T3: 50 per cent N through inorganic fertilizer + 50 per cent N through poultry manure, T4: 50 per cent N through inorganic fertilizer + 50 per cent N through horse manure, T5: 50 per cent N through inorganic fertilizer + 50 per cent N through vermicompost, T6: 50 per cent N through inorganic fertilizer + 50 per cent N through swine manure, T7: 50 per cent N through inorganic fertilizer + 50 per cent N through sheep and goat manure, T8: recommended package of practices + Azotobacter were replicatedthrice. The pooled data of experimental results revealed that integrated application of 50 per cent N through inorganic fertilizer + 50 per cent N through vermicompost recorded significantly superior growth parameters of the CO-4 hybrid napier viz., plant height, number of tillers and number of leaves/tillers and green fodder yield (254.27 t/ha/year) as compared to other treatments.
Key words: Fodder yield, forage crops, green fodder, Napier grass, organic manures
