The effect of mycorrhizae and elemental sulphur to the uptake of phosphorus by the plants

Phosphorus fixed strongly by the soil and hard for the uptake by the plants beside being at the limited level in the soils of our country high in clay and lime content in general is a limiting factor in the getting healthy growth of the plant production. The aim of this study was to investigate the inoculation of the root fungi called mycorrhizae, 100 mg/kg elemental sulphur addition for the effects on the biomass production, phosphorus uptake and the infection percent of soyabean and corn with the mycorrhizae based upon the applications of the mycorrhizae inoculation. The experiment was carried out in greenhouse and labotatory at University of Cukurova, Faculty of Agriculture, Department of Soil Science. The experiment was set up on two less fertile Çukurova soils such as Karaburun and Menekse. The experiment was arranged in separating separated parcels design in three replications. The values of dry matter production, phosphorus uptake and infection percent with mycorrhizae obtained from the soybean and corn grown in the sterilized soils of Karaburun and Menekse deficient in phosphorus used in the experiments were investigated. The shoot and root yield, phosphorus uptake and infection percent did not change by the addition of 100 mg/kg elemental sulfur compared to the control treatment. By the addition of mycorrhizae the shoot and root yield, phosphorus uptake and infection percent increased. The increase obtained by the addition of mycorrhizae in question did not change by the addition of mycorrhizae and 100 mg/kg elemental sulfur. The highest yield for corn and soyabean was obtained in the Menekse soil serial.The results indicated that 100 mg/kg elemental sulfur addition was not efficient in the yield and phosphorus uptake.Key Words: Soybean, Corn, Phosphorus, Elemental Sulphur, Mycorhizae
