Determination and mapping of calcium and magnesium contents using geostatistical techniques in oil palm plantation related to basal stem rot disease
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...

| Summary: | 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. |
