Sustainable Management in Crop Monocultures: The Impact of Retaining Forest on Oil Palm Yield
Figure 3
The relationship between oil palm yield and (a) elevation (m a.s.l.), and (b) distance to nearest non-native tree plantation.
Oil palm yield was measured as the mean deviation from the yield-by-age curve generated from Butler et al. [47] (yldB), and is quantified as the fresh fruit bunch weight per hectare (mt ha−1).
