Abstract: An investigation was carried out during 2008-2010 at the Research Station to study the effect of bio-fertilizers on nutrient status and fruit quality of Himsagar mango grown in new alluvial zone of West Bengal with the object to avoid indiscriminate use of chemical fertilizers and pesticides to save the natural ecosystem and increase the nutrient status of soil and fruit quality. Experimental findings revealed that, different combination of bio-fertilizers significantly improved the soil fertility and fruit quality of mango. Among different treatments, combined application of Azotobacter+Azospirillum+AM+PSM was most effective in improving the soil and fruit. The same treatment recorded maximum organic carbon (0.97%), available N (294.11 kg ha-1), P (37.44 kg ha-1) and K (231.00 kg ha-1) with maximum soil bacterial population as compared to control or RDF (recommend dose of fertilizer). Leaf nutrients were also improved with the application of bio-fertilizers. Therefore, it can be concluded that Azotobacter+Azospirillum+AM+PSM helps in improving the soil fertility and fruit quality of Himsagar mango.
