Its yield and fiber quality are affected by mineral nutrients, especially nitrogen (N), phosphorous (P), and potassium (K). In the present study, we aimed to quantify the influence of N, P, K fertilizers on plant growth, yield, and fiber quality. To this end, ramie plants grown under different fertilizer treatments (no fertilizer, N, P, K, NP, NK, PK, and NPK) were evaluated for differences in plant height, stem diameter, stem fresh and dry weights, number of stems, fiber fresh and dry weights, fiber quality (breaking strength, elongation, and diameter), and total N and P content.NPK, followed by NK, had the highest effect on plant growth, yield, and fiber quality, whereas P application had the least effect among all fertilization treatments. A strong correlation of fiber weight, elongation rate, and breaking strength was identified with stem diameter, stem fresh and dry weights, and N and P contents, suggesting that the combined application of NPK significantly enhances yield and fiber quality in ramie. Overall results suggested that optimum fertilization is important for a sustainable ramie production. Keywords: Growth, Fiber Quality, Nitrogen, Potassium Fertilization
