Abstract: Hybrid Napier grass is most adopted forage crops in Northern Karnataka due to its quick growth, high yield potential, better palatability, digestibility and rooting ability. It is advantages in various ways such as saving in cost of production, and high yield in short period. Rationing also offers an opportunity of continuous supply of green forage. Several Hybrid Napier crosses have been developed by the TNAU, IGFRI, UAS, Dharwad etc. It is very much need of the hours to study the performance of these hybrids under varying climatic conditions to know its suitability and yield potentiality. Keeping this in view a field experiment was conducted at Krishi Vigyana Kendra, Vijaypaura, Karnataka for two subsequent years of 2018-19 and 2019-20 under irrigated conditions in medium black soils having 0.58 per cent organic carbon, 211 kg/ha available Nitrogen, 56 kg/ha available Phosphorus and 135 kg/ha available Potassium with 8.2 pH. to explore the performance of Hybrid Napier grasses under irrigated condition. The treatments comprised eight Hybrid Napier cultivar, viz., NB-21, DHN-6, APBN-1, IGFRI-7, Phule Jaywanth, CO-3, CO-5 and DHN-15. A total of eight treatments were laid out in randomized block design with three replications. The pooled results of two years revealed that, Hybrid Napier cv. DHN-15 recorded significantly higher green fodder yield (759 q/ha). However which was on par with the hybrid napier cultivar DHN-6, CO-3, CO-5, Phule Jaywanth and APBN-1. Significantly lower green fodder yield was recorded by NB-21 cultivar (445 q/ha). Among different perennial grasses, the highest net returns (Rs. 59401 ha^-1) and BC ratio (2.68) was obtained with Hybrid Napier cultivar DHN-15 and closely followed by DHN-6, CO-3, CO-5, Phule Jaywanth and APBN-1. The lowest was with NB-21 cultivar (Rs. 22174 ha^-1 & 1.66, respectively).
