Abstract
To study the role of microorganisms in the solubility and availability of phosphorus from Rock phosphate and phosphate fertilizer (TSP) in calcareous soil and their effect on growth and Wheat yield. Pots factorial experiment was conducted,using SiCL sterilized soil with RCBD design. The experiment included 60 units result of combination of two treatments of mycorrhiza, two treatments of Apergillus fungus inoculums, three levels of TSP fertilizer and two levels of rock phosphate. Results showed significant increase in height plant when Mycorrhiza and Aspergillus inoculants were added which reached 4.87% , 3.37% respectively. While interaction treatments between TSP and rock phosphate gave significant increase in height plant which were 10.19% , 13.31% compared with control. Also results showed significant increases in the plant biological product in interaction treatments between Aspergillus, Mycorrhiza and phosphate fertilizer which were 17% , 73.89% , 61,10% respectively. While the interaction gave significant increases in nitrogen concentration in the plant shoot during branched stage which reached 32% , 58.69% , 25% while this increases at harvested period were 50% , 80% , 20% for the same treatments mentioned above compared with control. Also Mycorrhiza were gave significant increase in the available of phosphorus concentration in the soil which was 53.2% at branched stage while the same treatment was gave 18.72 at harvested period. Aspergillus treatment also gave an increase in the availability 0f phosphorus in the soil which were 28% and 9.5% at branched and harvested stage respectively. While the interaction between microorganisms gave active role and increases in the availability of phosphorus in the soil through two stages which were 42.72% and 82.40% at branched and harvested period respectively compared with the control which gave 5.16% and 2.4% for the two period respectively.
