Chemicals have accumulated in crops and soil as a result of widespread usage of chemical fertilizers, which has impacted the food chain. The purpose of this study was to examine the combined effects of biofertilizers containing microbial consortia of Azotobacter sp., Bacillus sp., and Trichoderma sp. on the vegetative growth of wheat plants. The bioreactor built in our lab, fruit waste, such as melon, banana, and papaya peels, potato peels served as the only source of nutrients for the growth of microbial consortia as well as prolong treatment of consortia on agrowaste was studied in case of liquid biofertilizer. The results demonstrated that the microbial inoculants produced using the developed bioreactor can be effectively used as biostimulant for the tested wheat plant. The macro- and micronutrient analysis of the batch 1 biostimulant revealed significant increase (P ≤ 0.05) in available nitrogen at 600 ± 10.44 mg/kg and potassium at and 1889 ±13.45 mg/kg, respectively, as compared to control. By the Pot culture bioassay and the experimental plants showed better growth than those of the baseline plants. The biostimulant batch 1 showed efficient plant growth-promoting potential, and the average root, shoot, and total heights of the plants were significantly greater (P ≤ 0.05) than those of the control group. The average root and shoot lengths were 16.6 ± 1.14 cm and 19.0 ± 1.3 cm, respectively. The average height was found to be 36 ± 0.71 cm. Plant height, root length, and shoot length changes were substantially different from control plants by Tukey's Honestly Significant Difference at the 5% significant level. The resultant growth stimulation can be linked to a valuable increase in the N and K content of the treated waste.
