Since VA mycorrhizal fungi cannot be propagated on artificial media, pot culture technique developed by Menge is currently being used for inoculum production. This study attempted to use appropriate media and suitable host plant to produce mass inoculum of VA mycorrhiza. The appropriate media were selected from 7 plant growth media; sand, clay, peat, loamy sand, rice husks, coconut coir dust, vermiculite and two combination of sand+peat and sand+clay in ratio 1:1 by volume. Sand+clay and sterilized peat were the best media for producing VAM spores in pot culture. A suitable host plant was selected from 10 cultivars of; onion, sorghum, corn, soybean, mungbean, peanut, sabi, bahia grass, kudzu and cabbage (which was a nonmycorrhizal plant). Soybean, corn and sorghum were the most suitable host plants for producing inoculum followed by peanut and kudzu.
