The collective utilization of biochar and organic manure represents the profit to plants and nutrient cycling. In this experiment, the maize (stalk and cob) biomass was pyrolyzed at 600 °C and morpho-mineralogically characterized. The scanning electron microscope (SEM) image represented cross-linked pores and feathery plate–like layer construction on the surface of biochar. The 75:25 ratio combinations of organic manure and biochar were the best for developing low-cost biochar co-compost technology. The maximum increase in pH was observed in biochar-poultry manure (7.05) co-compost followed by pig manure (6.97), goat manure (9.93), vermicompost (6.85), and FYM (6.83) co-compost. The release of cumulative CO2 decreased with increase in biochar ratio in biochar co-compost mixture. The organic manure/biochar (co-compost) ratio at 75:25 enhanced maximum yield in poultry manure (4528 and 1027 kg/ha) followed by goat manure (4378 and 1016 kg/ha), vermicompost (4278 and 986 kg/ha), pig manure (4218 and 956 kg/ha), and FYM (4178 and 949 kg/ha) for maize and black gram, respectively. The poultry75+BC25 results in maximum grain nitrogen content in both maize and black gram and minimum with FYM25+BC75. Lastly, with increase in biochar ratio in co-compost, the specific leaf weight and chlorophyll content significantly increased. Thus, the encouraging role of biochar co-compost on crop growth, yield, soil health, and physiology proposes that it is a superior technique to overcome biochar's intrinsic nutrient deficit, making it a proper way serving to refine farm-scale nutrient cycles.
