Abstract:
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 comprises T₁: recommended package of practices, T₂: 50 percent N through inorganic fertilizer + 50 percent N through FYM, T₃: 50 percent N through inorganic fertilizer + 50 percent N through poultry manure, T₄: 50 percent N through inorganic fertilizer + 50 percent N through horse manure, T₅: 50 percent N through inorganic fertilizer + 50 percent N through vermicompost, T₆: 50 percent N through inorganic fertilizer + 50 percent N through swine manure, T₇: 50 percent N through inorganic fertilizer + 50 percent N through sheep and goat manure, T₈: recommended package of practices + Azotobacter were replicated thrice. The pooled data of experimental results revealed that integrated application of 50 percent N through inorganic fertilizer + 50 percent 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^-1year^-1) as compared to other treatments.
