Arbuscular mycorrhizal fungi (AM fungi) have been found associated with a wide variety of agricultural and horticultural crops, but in legumes it occurs widely. The experiments were conducted during spring season 2017 under pot house conditions. The effect of inoculation of AM Fungi colonization and P amendments on growth and yield of Mungbean plants was investigated. The results revealed the overall increase in plant growth parameters and yield of Mungbean plants. In AM Fungi inoculated pots, the root as well as leaf surface area were also enhanced significantly due to the colonization of Glomus macrocarpon (AM Fungi) as compared to uninoculated plots. Among three levels of Phosphorus; 0, 40 and 80 mg/kg soil, the maximum increase in root and shoot length, their fresh and dry weight was recorded at 40 mg P/kg soil in 15, 30, 45 and 60 days old Mungbean plants as compared to 80 and 0 mg P/kg soil levels. The number of leaves and pods per plant, their fresh and dry weight was also found maximum at 40 mg P/kg soil level. Maximum increase in plant growth and yield of Mungbean plants were recorded in the pots combined inoculated with Glomus macrocarpon and phosphorus. It is suggested that Arbuscular Mycorrhizal Fungi have the potential to act as bio-fertilizer.
