Spatial Variability of Oil Palm Leaf Nutrients and Yield

In recent times, among the major problems in oil palm plantation is the lack of proper interpretation of yield maps for site-specific management, the identification, and understanding of the causal factors influencing the variability of oil palm yields. The ability to find and comprehend the leaf...
