The study looked at how using bio-organic fertilizer on spring tea plants affects their growth, yield, and economic value. They made two types of high-quality fertilizer from chicken manure, corn stalk, and cattle manure. Applying these fertilizers, along with inorganic and organic ones, increased tea yield by up to 23.5%. The tea leaves had more nutrients with fertilization. The bio-organic fertilizers were safe and effective, improving tea quality and boosting profits.
