In order to investigate the possibility of replacing triple superphosphate fertilizer with biological fertilizers in mung bean cultivation, an experiment was randomized block design with 3 replications, in a split-plot arrangement was conducted in a research field in Malekshahi town, Ilam province, Iran in 2013. Treatments include five levels of triple superphosphate fertilizer (P) as the main plot including 0, 25, 50, 75, and 100% of the recommended amount, and biofertilizer (B) as a sub-plot in four levels including: without inoculation (B0), mycorrhiza (B1), phosphate solubilizing bacteria (Pseudomonas) (B2) and combination of mycorrhiza and pseudomonas (B3). Results showed that phosphorous fertilizer significantly affected whole studied traits excluding root nodes number. The highest and lowest seed yield was achieved with 75% of triple superphosphate fertilizer, 1354.45 kg/ha, which showed a 73% increase compared to the control (no phosphorus fertilizer). Also, results showed that biofertilizer had a significant effect on all studied traits excluding days to reaching so the greatest grain yield obtained in pseudomonas treatment by 1238.82 kg/ha. Overall results showed that biofertilizers from different sources could reduce phosphorous fertilizer requirement and so result in increasing yield
