A field experiment titled “Effect of bioinoculant on growth, yield and quality of mango (Mangifera indica L.) cv. Kesar” was carried out during 2024-25 at the College of Agriculture, Badnapur, in collaboration with Mahyco Company at their research field in Jalna. The study included various treatments using biofertilizers (Azotobacter and PSB) along with vermicompost and was arranged in a Randomized Block Design (RBD).

Among all the treatments, T₉, which consisted of Azotobacter (50 g per plant) + PSB (50 g per plant) combined with 3 kg of vermicompost per plant, proved to be significantly superior in several growth and development parameters, including percent increase in leaf length (9.64%) and fruit weight (356.00 g).

For other parameters, the highest plant height (11.83%) and maximum leaf area increase (9.69%) were recorded in the control treatment (T₁₀). The shortest duration for achieving 50% flowering (11.78%) and the fastest transition from flower bud initiation to fruit set (36.14%) were observed in T₉. The highest number of flowers per panicle (2666.67) occurred in T₁, while the maximum number of fruits at the marble stage (8.62) was recorded in the control (T₁₀).

Treatment T₃ produced the greatest number of fruits at harvest (333.33) and also recorded the minimum fruit drop (82.00), along with the highest increase in fruit retention (8.33%). The longest fruits (13.26 cm) were obtained from T₇, and the largest fruit diameter (9.93 cm) from T₁. The highest average fruit yield per tree (45.96 kg) was observed in T₈, whereas the maximum juice percentage (52.6%) was found in the control (T₁₀).

Additionally, the control treatment (T₁₀) recorded the highest values for TSS (24.4 °Brix), acidity (0.55%), and total sugar content (13.64%).
