Abstract

The basal stem rot (BSR) disease had been reported as the most destructive disease of oil palm in Southeast Asia. Adequate contents of nutrient in soil and leaf helps improve the plant health and its productivity. This study aims to determine the spatial variability of Ca and Mg in soil and leaf collected at BSR infected oil palm plantation. The Ca ex. and Mg ex. in soil were found low in the study area ranged from 0.03-0.50% and 0.06 – 0.35%, respectively. The Ca and Mg content in leaf were also low ranged from 0.09-0.60%, and 0.03-1.87%, respectively. The Ca ex. in soil of both blocks showed a negative significant correlation with the disease at p<0.01. However, only Ca content in leaf of block 2 showed a negative significant correlations with the disease (p<0.05). The generated map and significant correlations revealed that unbalanced nutrient content occurred in the study area.
