Abstract |
A pot experiment was executed with sorghum plants grown in sterilized or non-sterilized clayey or sandy soils, and inoculated with mycorrhizal fungus Glomus aggregatum. Sorghum plants were supplemented with either rock or super phosphate or left without phosphorus fertilization.
Results showed that, mycorrhizal inoculation with G. aggregatum resulted in variable increases in shoot dry weight and phosphorus contents of sorghum plants. The growth of sorghum plants in super-P treated sandy soil was quite equal if the plants inoculated with G. aggregatum or not. G. aggregatum inoculation were more pronounced in sterilized rock-p- treated soil than in non-sterilized ones. However, in the sandy soil, G. aggregatum was very effective in improving plant growth and P uptake, regardless of soil sterilization.
In the presence of super-P, the improvement of plant growth due to G. aggregatum was more pronounced in non-sterilized soils than in sterilized ones. Mycorrhizal colonization was slightly affected by rock- P application, but super-P depressed the degree of infection by native or introduced VAM fungi. The introduction of G. aggregatum with applica- tion of rock- P had almost similar effect to that of super-P without mycorrhizal inoculation
