The relationship between the nutritional status of mango (Mangifera indica L), cashew (Anacardium occdentale L) and durian (Durio zibethinus L) from three different agro-ecological zones from Peninsular Malaysia was attempted based on the data obtained from earlier studies. In the pronounced dry zone of northern Malaysia, there appeared to be a weak relationship between the soil moisture content during the wet season and the nutrient concentration in mango leaves. As the trees were young, the relationship between the nutritional status and the tree phenology is not clear, although the Ca contents increased substantially as the trees get older. In the monsoonal zone on the east coast, however, mature cashew on sandy Spodosols, also did not show clear relationship between the nutritional status and the tree phenology. However, the organic matter contents of the sandy Spodosols clearly differentiated between the good, healthy high yielding from the poor, low yielding trees. In the wet environment of central Malaysia, the nutritional status of mature durian was not affected by either the tree phenology or the rainfall pattern. In all these studies, however, there is a need for proper selection of leaves with stable nutrient concentration at various appropriate phenological stages under each environment. Nevertheless, the information from these studies could from the basis for further more in-depth studies on the subject.
