| Abstract | The study aims to promote plant growth, soil fertility and soil microbiota using a combination of Bacillus pumilus AR57 and chicken feather protein hydrolysate (CFPH). The bacterium-mediated CFPH (5 % v/v) was found to be the optimum biostimulant concentration that showed significant maize plant (Zea mays L.) growth and enhanced its phytochemical contents (3.7 folds chlorophyll, 1.3 folds protein, 2.3 folds carbohydrate). The addition of CFPH to soil eventually showed a remarkable increase in the soil fertility and microbial community (hetero-trophic, 42.23 x 106 CFU/g, nitrogen fixers, 2.45 x 104 CFU/g, phosphate solubilizers, 0.48 x104 CFU/g and potassium solubilizers, 0.33 x104 CFU/g). Bacillus sp. is considered the universal cell factory and secretory machine of bioactive peptides. B. pumilus AR57 positively influenced plant growth as a biofertilizer and may develop an adaptive immunity against plant pathogens. The CFPH exhibited an excellent shelf-life of protein stability (719 mu g/ml) on the 10th day when stored at 4 degrees C. Conclusively, the Chick 'n' Farm, our in-house, unprocessed biostimulant, emerged as an effective alternative biostimulant and biofertilizer that replaces the existing chemical fertilizers and enriches the soils' biotic and abiotic factors that will play an inevitable role in the sustainable agriculture and circular economy. |
