The current research aimed to assess the impact of microbial consortia on flowering behaviour, fruit set, and yield performance of mango cv. Kesar. The experiment was set in a RBD (Randomized Block Design) having ten treatments that were repeated three times each. There were significant treatment differences in all the measured parameters. First flowering was recorded in T₁₀ (85.76 days) the shortest and the control (T₁) recorded the longest (96.99 days). T₁₀ also produced the highest number of panicles per branch (1398.67) compared to the minimum in T₁ (1127.50). T₁₀ had the maximum panicle length (38.38 cm) and T₁ had the lowest (19.90 cm). Microbial consortia had a significant positive effect on fruit set, with the highest values of T₁₀ being observed at the pea stage (14.70) and marble stage (1.56). Fruit retention improved substantially under T₁₀ (44.59%), whereas the lowest was noted in T₁ (34.94%). T₁₀ had minimum fruit drop at harvest 54.53% whereas T₁ had the highest 65.88%. The same pattern was observed in the yield-attributing characteristics where T₁₀ had the greatest number of fruits per plant (208.00), and highest fruit weight (347.19 g) and fruit yield (72.22 kg/tree). In general, the outcomes show that the microbial community of Azotobacter, PSB, and ZnSB (T₁₀) has a profound positive effect on flowering efficiency, fruit set, retention, and yield of mango cv. Kesar, suggesting that it has a high potential to be used as a sustainable biofertilization method.
