Abstract
To examine the critical level of arbuscular-mycorrhizal (AM) fungi for Prosopis cineraria under nursery seedling production, Glomus sp. was used at different spore levels (0, 100, 200, 300, 400, 500, 600, 700, 800 and 900 spores per seedling per polybag). Mycorrhizal inoculation increased plant height, dry matter yield, root length and per cent root infection. Eighty five per cent infections were found to be sufficient for optimum response by P. cineraria seedling. The critical level of spores was found to be 400 per polybag (1 kg soil).
