The aim of the present study was to assess the influence of phosphorus levels and phosphorus solubilizing fungi on yield and nutrient uptake by wheat. The dry matter production by wheat at tillering, ear emergence, and harvest was significantly higher with 90？kg？P2O5？ha？1 and was at par with 60？kg？P2O5？ha？1. Application of Aspergillus awamori gave the highest dry matter accumulation at tillering, ear emergence, and harvest stage of crop growth. Increasing levels of phosphorus increased the grain and straw yield significantly up to 60？kg？P2O5？ha？1 of wheat crop. However, the maximum grain and straw yield were obtained at 90？kg？P2O5？ha？1, which was at par with 60？kg？P2O5？ha？1. The combined application of 60？kg？P2O5？ha？1 with A. awamori recorded significantly higher grain and straw yield. Increasing level of P application (0 to 90？kg？P2O5？ha？1) and inoculation with A. awamori and A. niger significantly increased uptake of N, P, and K in wheat at all stages of crop growth. The maximum nitrogen, phosphorus, and potassium uptake was recorded at harvest (grain and straw) followed by ear emergence and tillering when seeds were inoculated with Aspergillus awamori. 1. Introduction Wheat (Triticum aestivum (L.)) is the second most important food grain crop in India ranking next to rice (Oryza sativa L.) contributing about 35% of the food grain production. India occupies second position next to China in the world with regard to area (27.7 million hectares) and production (77.6 million tonnes) of wheat. Rajasthan state has an area of 2.10 million hectares under wheat cultivation which is 7.95 per cent of the total cultivated area. The average productivity of wheat in the state is 31.75？q？ha？1 [1]. This clearly indicates that in spite of considerable improvement in genetic potential of the crop, productivity is still very poor in the country (28.06？q？ha？1) as well as in the state of Rajasthan. One of the reasons of low productivity is poor efficiency and low availability of phosphorus in soil due to high fixation. The high productivity of wheat can only be achieved by the adoption of suitable variety and improved agronomic practices with balanced and judicious use of chemical fertilizers in an integrated way. Phosphorus is one of the most important major nutrients required for the growth and development of crop plants. It plays a vital role in virtually every plant process like photosynthesis, energy storage and transfer, stimulating root development and growth, giving plant rapid and vigorous start leading to better tillering in wheat, and encouraging earlier
