| Abstract:
The effect of rainfall, age and position of the leaf on the nutrient contents of cashew (Anacardium occidentale L.) planted on tin tailing was studied for one year (1976). The young leaves showed significantly higher N, P and K contents than older leaves. During dry months, the N and K contents were higher in young leaves than during wet months, indicating the mobility of these nutrients in leaves. Leaves sampled at the growing terminal had significantly higher nutrient contents than those at the basal parts of the branch. The agronomic significance in relation to the manuring programme of cashew on sandy tin tailing under the agro-environment in Malayasia is discussed. | |
