摘要

Chicken feather compost, rich in organic matter and essential nutrients, can significantly enhance crop growth and physiological performance. This study evaluates the impact of chicken feather compost on Solanum melongena (Pusa Brinjal Long) growth under varying compost levels (6 and 12%). The optimized composting conditions, identified using Response Surface Methodology (RSM), included 6.25% chicken feathers and 12% Bacillus cereus inoculum. Results showed significant improvements in plant height, leaf area, biomass, flower and fruit production, chlorophyll content, and physiological processes with compost treatments compared to the control. 12% compost treatment resulted in 23.2% taller plants at 40 DAT and 15.9% taller plants at 75 DAT compared to the control. Leaf area increased by 7.91%, while total chlorophyll content rose by 45.3% in 12% compost group relative to the control. Physiological measurements indicated 43% higher photosynthetic rate and 79.1% reduction in respiration rate in 12% compost group compared to the control, reflecting improved metabolic efficiency. Shoot fresh weight and dry weight were 7.65% and 47.3% higher in 12% compost group, while root fresh weight increased by 40% and root dry weight by 85.6%. Total fruit yield in 12% compost group was 627.4% higher than the control. These findings highlight the effectiveness of chicken feather compost as an organic amendment for enhancing plant growth, yield, and physiological performance. This research underscores the potential of repurposing poultry waste into nutrient-rich compost, promoting sustainable agricultural practices while addressing waste management challenges.
