The effect of different levels of N, P and K on vegetative growth, flowering, fruit set, fruit quality and leaf composition of G. asiatica was studied in sand culture. High doses of N, P and K significantly stimulated the vegetative growth of plants, N being the most effective. Plants receiving a deficient supply of N, P or K showed acute stunted growth with little branching and few smaller leaves, the effect being most pronounced due to N deficiency. The plants also developed characteristic deficiency symptoms on the foliage. The N, P and K deficient plants did not flower. Fruits under high N and P showed more total sugar content and less acidity, while high K increased the acidity and decreased the sugar content of the fruits. The N content of the leaves was raised by increasing levels of N, but was not appreciably affected by P or K levels. Foliar P content was increased by added P and N, but not by high K supply. Leaf K content was slightly increased by high K supply, decreased by high N, and was not influenced by P levels.
