| Abstract | ||||
| Eighteen actinomycetes strains were isolated from rhizosphere soils taken from experimental farm of faculty of agriculture, Assiut University, Egypt, planted with wheat, faba bean and clover. Out of the 18 isolates, 9 (50 %) showed an ability to solubilize inorganic phosphates, based on inducing clear zones around their colonies growing on a tricalcium phosphate medium after incubation for 10 days at 28 °C. The phosphate solubilization index of strains A1, A2, A3, A4, A5, A7, A8, A10 and A18 on pikovskaya,s modified agar medium were 3.40, 2.40, 2.57, 4.50, 3.10, 1.57, 2.10, 3.83 and 1.83, respectively | ||||
