A field study was conducted to assess the nutritional requirements of newly evolved wheat genotype, 51-91195. The crop was treated with ten combinations of N and P employed in different ratios. The results revealed that the agronomic parameters like plant height, grain/spike, grain weight/spike and 100-grain weight were influenced significantly by the application of N and P and were maximum at balanced N and P ratios. Generally, the yield increased with increasing N and P levels but Afferent ratios of N and P influenced economic harvests more significantly. The highest biological yield was recorded with 180 kg N and 90 kg P205 Ita4 which was statistically identical to that produced by 120 kg N and 90 kg P205 ha-7. The yield trend clearly indicated that application of N and P205 at 4:3 ratio improved their efficiency of utilization. Since the test genotype (S1-91195), produced maximum economic yield at 120 kg N and 90 kg P205 ha-1 with the highest value cost ratio, hence it could be adopted as the mast efficient dose.
