Effects of Mycorrhizal Fungi with Phosphate Fertilizer Applications on Phosphate Solubilizing and Soil Properties of Grapes Orchard

The objective of this study was to efficiency determined of mycorrhizal fungi with different phosphate fertilizer application on phosphate solubilizing and soil properties of grapes orchard. The treatments were arranged in 2x5 factorials in Randomized Complete Block Design (RCBD) with 5 replications. Factor 1- two levels of mycorrhizal fungi were non-inoculation and inoculation. Factor 2- five levels of phosphate fertilizer application were 0, 27.17, 54.34, 81.52 and 108.69 g plant-1 by soil analysis recommendation. The collected data was spore number, root colonization density, phosphatases activity of mycorrhizal fungi, available phosphorus (P) in soil, soil pH and phosphorus in leaf. The results showed that the inoculation of mycorrhizal fungi increased spore number, root colonization density, phosphatases activity of mycorrhizal fungi, available P in soil and P in leaf compared with the non-inoculated. While, phosphate fertilizer at a rate 54.34 g plant-1 increased spore number, root colonization density, phosphatases activity of mycorrhizal fungi, available P in soil and P in leaf. Mycorrhizal fungi combination with 54.34 g plant-1 of phosphate fertilizer increased spore number, root colonization density, phosphatases activity and available P in soil.
