Abstract
A comparative study was made of mulched and unprotected planting of tomato on a neutral purple soil. With adequate P and K as basal fertilizer, plant height, fruit weight, the contents of N, P and K of the plants and their fruit yield increased with N rate. However, excessive N application resulted in yield decrease. With similar fertilizer rates, mulching treatment gave 11.19%～23.29% greater plant height and 3.26%～19.01% higher yield than the unprotected cultivation treatment. Thus mulching significantly improved fertilizer efficiency. Different fertilizer combinations had little influence on the total content of soluble solids, while sugar content of the fruit was considerably influenced by nutrient supply. N combined with P and K promoted, to some extent, the quality of the fruit.
