Abstract: Fodder crops cultivation in India is gaining momentum to overcome the feed and fodder shortages for the farm animals. Application of nutrients for fodder crops is a rare phenomenon and the package of practices are not adopted by the farmers to increase the productivity. Fodder crops are almost negligible crops in our country. Field experiments were conducted in order to study the response of Bajra Napier hybrid grass to various levels of nutrients in different seasons. Top dressing of 100 Kg/ha of Nitrogen (N) after each cut is the normal recommendation. However, information on top dressing of Phosphorous (P) and potassium (K) in the region is not available. Hence, this field study was carried out with the objectives to assess the response of Bajra Napier hybrid grass to various levels of nutrients <em>viz.,</em> N, P&amp;K and find the optimum dose for getting maximum yield. The experiment was laid out in Randomized Block Design with three replications. All the three major nutrients were tried in seven levels. Basal dose of 50:50:40 kg/ha of N, P₂ O₅&amp; K₂ O applied commonly for all the plots at the time of planting. 100 kg nitrogen, 50 kg phosphorous and 40 kg Potassium kept as 100 % RDF. After each cut N, P &amp; K were applied as top dress at various levels. The green fodder yield was recorded. The results revealed that there was a gradual increasing trend in the green fodder yield with increase in the nutrient levels. Beyond the optimum dose declining trend was observed. With regard to various levels of nutrients N @ 200% (200 Kg/ha), P@50 % (25 kg/ha) and K @ 150% (60 Kg/ha) after each cut was found to be the best for getting the highest green fodder yield in Bajra Napeir Hybrid grass.
