A field experiment was conducted during 2013-14 and 2014-15 at Izatnagar, Uttar Pradesh, to study the effect of integrated nutrient management in napier hybrid grass production under irrigation. Experiment was conducted with application of 100 % RDF (Recommended dose of fertilizers), 75% RDF along with 5t/ha Vermi-compost + bio-fertilizers, 75% RDF along with 5t/ha FYM + bio-fertilizers and 75% RDF alone. Four cuttings were taken at the interval of 90 days after planting during both the years. Plant height, green fodder yield, dry yield, crude protein yield, etc. were estimated. Application of 75% RDF along with 5t/ha Vermi-compost + bio-fertilizers gave significant higher plant growth and mean yield of fodder (69.75 t/ha/cut) than 100 % RDF alone (65.35t/ha/cut) followed by 75% RDF +5t/ha FYM + bio-fertilizers application (67.73 t/ha/cut). It has been observed that 25 % of RDF can spared successfully without compromising the fodder production if Vermi-compost and or FYM added @ of 5 tones per hectare along with bio-fertilizers. Result also shows that 75 % RDF alone significantly lowers the yield of green fodder (58.48t/ha) and dry matter yield (11.07 t/ha). First cut produced significantly higher yield of fodder, DM, CP, CF over the 3rd and 4th cut. However, it was at par with second cut of Napier hybrid grass.
