Abstract
The effect of inoculation of the phosphate-solubilizing microorganisms (PSM) Bacillus circulans and Cladosporium herbarum and the arbuscular mycorrhizal (AM) fungus Glomus fasciculatum with or without Mussoorie rockphosphate (MRP) was studied in a P-deficient natural non-disinfected sandy soil on mungbean (Vigna radiata). The AM levels increased following the addition of MRP or inoculation with PSM or G. fasciculatum. Both grain and straw yield of mungbean increased following inoculation with PSM or the AM fungus. In general, the increase in yield was higher in the presence of MRP and inoculation with a combination of PSM and AM fungus. Highest N and P uptake by mungbean was recorded after treatment with a combination of B. circulans, C. herbarum and G. fasciculatum in the presence of MRP. Generally the PSM population increased after AM fungus inoculation.
