Abstract: A field experiment entitled “Effect of biofertilizers on growth and development of mango plants (Mangifera indica L.) cv. Dashehari” was conducted during the year 2017-18, at the Fruit Instructional Farm, Department of Fruit Science, College of Horticulture and Forestry, Jhalawar. The experiment consisted of different treatments of biofertilizers (Azotobacter and PSB) and Vermicompost and was laid out in Randomized Block Design. Amongst different biofertilizers treatments application, treatment T₉ comprising biofertilizers (Azotobacter 50 g per plant + PSB 50 g per plant) along with 3 kg Vermicompost per plant was found significantly superior over other treatments with respect to growth and development parameters such as per cent increase in plant height, rootstock girth, scion girth, number of shoots per plant, number of nodes per shoot in mango cv. Dashehari. T₉ treatment has also given better results in enhancing the organic carbon percentage, available N, P and K content of soil status and was found significantly superior over other treatments. Like-wise, soil pH and electrical conductivity also reduced significantly under T₉ treatment over other treatments. Overall, T₉ treatment exhibited better plant growth and development parameters and improvement in soil health of mango cv. Dashehari plants as compared to other treatments of biofertilizers.
