Abstract

Growth and early yield of mangosteen Garcinia mangostana L. trees grown under natural shade trees of Indigofera tasmania were studied in comparison with those grown under full sunlight at MARDI Research Station Bukit Tangga Kedah. Results showed that trees under shaded condition were more vigorous with heightstem diameter and canopy spread increment rates significantly higher than those trees grown in the open. Improved growth among shaded trees was largerly due to bigger leaf size and higher stomatal conductance. Pre-bearing period was not influence by shade. However fruit yield in the first two years of bearing showed that trees planted under natural shade had significantly higher fruit number as compared to those unshaded. The prospect of using natural shade plants for planting mangosteen under the agro-forestry concept is good as long as the shade level could be maintained between 30-50. It was found that Indigofera tasmania is not a good choice due to their high tendency to overshadingif not properly maintained. This species also flowered and shed their leaves during the drought months leading to their inability to give shade during critical conditions.
