Description :
This study explores the effective hydrolysis of keratin from chicken feathers and its application as a bioavailable amino acid source to promote plant growth. The Trichloroacetic Acid (TCA) Test confirmed complete keratin hydrolysis, while the Ninhydrin Test validated the presence of primary and secondary amino acids in the hydrolysate. Experimental trials demonstrated that a 2 ml amino acid concentration in 100 ml water optimally enhanced seed germination (83%) and root (6.0 cm) and shoot (8.0 cm) growth. Higher concentrations (>3 ml) negatively impacted growth, likely due to nutrient oversaturation. These findings underscore the potential of feather-derived amino acids as sustainable agricultural supplements, simultaneously addressing waste management challenges. Further studies are recommended to explore long-term applications and species-specific effects.
