Effect of Soil Factors on Arbuscular Mycorrhizal Fungi of Castor [Ricinus communis (L.)]

B Aruna, K Geetha

Abstract: The rhizospheric soil samples of castor collected from ten (10) different localities of Mahabubnagar district were analyzed for physico-chemical parameters. The data on rhizosphere soil analysis of physico-chemical characteristics viz. , soil texture varied from sandy clay, sandy to clayey type, pH was neutral (7.0) to moderately alkaline (8.0), Electricon conductivity (EC) ranged from normal (0.07 mmhos/cm) to satisfactory levels (0.86mmhos/cm). The soils were optimum in nutrient levels particularly with Organic Carbon ranged from low (
