Abstract

Leaf samples were taken from 6 successive positions on fruiting shoots of the March-April flush of Lucknow-49 guava (Psidium guajava L.) at monthly intervals up to 6 months. Dry matter content of leaves increased with age and from basal to terminal leaves. Levels of N, P, K, Zn and Cu decreased while those of Ca, Mg, Na and Mn increased at different leaf ages. Basal leaves were higher in P, K, Na, Zn and Mn content while the reverse was true for N and Ca. No definite pattern was observed for Mg and Cu concentration with regard to position of leaf on the shoot.
