The status of arbuscular mycorrhizal (AM) fungi associated with Jatropha curcas grown on two different soil types: black cotton soil and red-murumy soil, in Jabalpur, Madhya Pradesh, India, was investigated. Results showed that the spore population in the rhizosphere of J. curcas in the black cotton soil was 328 spores per 100 grams of soil. Red murumy soil recorded less population with 207 spores per 100 grams of soil. The available nitrogen, phosphorus and potassium contents in the black cotton and red murumy soils were 147.4 and 326, 10.14 and 22.15 and 240 and 216 kg/ha, respectively. The poor contents of phosphorus in black cotton soil enhanced the VAM spore population and its infection in roots. The frequency of all the ten AM fungi varied considerably on both soil types. Other helper bacteria such as Azospirillum, phosphate solubilizing bacteria and fluorescent bacteria were also isolated from the rhizosphere of J. curcas. AM fungi of genus Glomus, Acaulospora, Gigaspora and Scutellospora were commonly found in both soils. Glomus mosseae was the dominant species to occur in the black cotton soil (80%). In red murumy soil, Acaulospora scrobiculata was found to be the dominant species with 78.8% occurrence. |
