Methods of Reducing Inorganic Fertilizers with Aspergillus Fungi on Oryza Sativa

This study was conducted to determine the optimum dosage of Aspergilus sp fungi originating from the rhizosphere of regular paddy rice in inorganic P fertilizer in binding to phosphate solubility, as well as growth and production in order to reduce the use of inorganic P fertilizer in rice paddy. and production of lowland rice. To determine the interaction of the administration of Aspergilus, sp and P inorganic phosphate solvents and increase phosphate availability and the growth and production of lowland rice. The results obtained after the application of inorganic P fertilizer to rice paddy plants that the application of phosphate solvent mushrooms can increase plant height, number of productive tillers, P uptake and 1000 grains of wet grain higher than without P solvent mushroom administration. plant height, number of productive tillers, P uptake, and 1000 grains of wet grain were higher than those without inorganic P fertilizer. The interaction of phosphate solvent fungus treatment with inorganic fertilizer (4 kg / plot of 100% inorganic P fertilizer) can increase plant height
