| Summary: | Mango is one of the most consumed fruits in the world. At the cultivation stage of this plant, soil and plant nutrient management plays an important role for optimum growth. However, soil and plant nutrient contents of each tree may be different and influenced by tree age and may require a different management practice. Therefore, the objectives of this study were to examine the soil and plant nutrient contents of different ages of mango tree and to investigate their relationship. Soil and leaf samples were collected from Harumanis trees aged 12 and 38 years in Arau, Perlis. Soil samples were collected at a depth of 0–30 cm while the third or fourth mango leaf from the current flushes of the plant were collected as samples. The analyses for both soil and leaves were conducted following the standard practice. The results demonstrated that there was no significant difference among the measured parameters except for EC and total N in the soil, and K and Ca in the plant nutrient contents between both the ages of the trees. The translocation of N, P and Ca were significantly higher in the tree aged 12 years. Meanwhile soil and plant relationship show that soil pH and exchangeable bases (Ca, K, and Na) were highly correlated with Ca and N/Ca ratio in the tree aged 12 years while a highly negative correlation between total N and Ca was found in the tree aged 38 years. It is a concluded that, tree ages have an influence on the soil and plant and on their relationship as well. © 2024, Malaysian Society of Soil Science. All rights reserved.
