In order to investigate the impact of fertilization by utilization organic manures (gradable waste) at different levels (25, 50 and 75 %) combination with thee rates (50, 75 and 100%) mineralized NPK from its suggested doses, all treatments with or without a combination of biofertilizers, such as Bacillus megaterium, which dissolves phosphate, and Azotobacteras chroococcum, which fixes nitrogen Potassium-solubilizing bacteria Bacillus circulans on psedostem tallness and cinch, number of green leaves, leaf area, yield, crop quality and Williams banana plants' fruit heavy metal content. Banana plants that were 100% fertilized and inoculated with town waste manure produced the best results. Additionally, fruit quality and output were enhanced with biofertilizers including organic manure. Every evaluated parameter improved when the organic manure rate was increased, either with or without inoculation, especially when the rate was high. When N was provided from different both organic and mineral sources instead of just one, the chemical composition of Grand Nain banana fruits greatly improved. Natural fertilizer made from town trash improved fruit quality by increasing finger weight, soluble solids, and total sugar concentrations while decreasing starch and nitrate concentrations. Organic fertilization with 100% municipal waste, 50% mineralized NPK at the necessary rate, and biofertilizer inoculation produced the greatest results with all the traits of Grand Nain banana trees. Meanwhile, the increase in heavy metals concentration (Cd, Pb and Ni) in banana fruits did not reach to significant level. Moreover, using of organic and Biofertilizers reduced GHG emissions (No2 & Co₂) significantly through a strategy for mitigating
