| Summary: | Objective: This study aims to evaluate the effect of different chicken feather vermicompost rates collected from poultry waste and applied as organic fertilizers on the growth performance of sunflowers. Theoretical Framework: In this study, the chicken feather vermicompost was formulated based on the combination of chicken feathers, chicken dung, mushroom medium residue, and banana trunks. The completed chicken feather vermicompost was applied to the sunflower to evaluate the growth performance. Method: The methodology involved five different rates; T1 Control (300g organic fertilizer), T2 (200g chicken feather vermicompost), T3 (300g chicken feather vermicompost), T4 (400g chicken feather vermicompost), and T5 (500g chicken feather vermicompost). Total of 35 sunflower plants were applied with 5 treatments for 7 replications. Results and Discussion: The physio-chemical properties of chicken feather vermicompost, such as EC, pH, moisture, and temperature were optimal for decomposition organism growth and reproduction. The population and reproduction of Eudrilus eugeniae in vermicompost are influenced by all ingredients used in vermicomposting. The results show that the different chicken feather vermicompost rate affects sunflowers' growth performance. T5 exhibits the best performance in the number of flowers, number of leaves, relative chlorophyll content, fresh weight, and dry weight. Research Implications: By considering the chicken feather vermicomposting method, it is useful in reducing environmental pollution by managing waste efficiently. Originality/Value: This study provides a new technique for maximizing poultry waste through the chicken feather vermicomposting process and identifies the optimum rate of chicken feather vermicompost on growth performance of sunflowers for sustainable agriculture. © 2024, Editora Alumni In.
