In a field study, the effect of N, P, K and their combinations on the growth, yield and nutrient uptake pattern by mesta (Hibiscus cannabinus L.) was studied. No effect of N, P, K on growth characteristics like plant height and base diameter occurred up to 60 days. Effect of fertilizer treatments on plant growth was observed only after 90 days. The effect of N was more pronounced than P and K. Initially, growth of leaves was higher than both the bark and the wood. Nutrient concentration was at a maximum in the early stages of growth but declined with age and became steady at about 60 days. The quality of fibre obtained after 120 days of growth was assessed and the effect of nutrients on quality is discussed.
