Extended Data Fig. 7: Comparison of simulated and measured water-limited yield potential and attainable yield.
From: Fostering a climate-smart intensification for oil palm

In the case of water-limited yield potential (Yw), simulated values correspond to those derived from crop modelling in this study (see Extended Data Table 1) while published data (PD) correspond to highest recorded yields in plantations located in Southeast Asia as reported in the oil palm literature (see Supplementary Information, Section IIa). In the case of attainable yield (Yatt), values were estimated as 70% of simulated Yw in this study (see Extended Data Table 1) while large plantation (LP) values were derived from long-term yield records from 14 well-managed commercial blocks in Indonesia as provided by a number of private large plantations companies, including the four blocks used for calibration. Boxes indicate the 25th and 75th percentiles, whiskers represent the 10th and 90th percentiles, and means are shown with crosses. Also shown is the sample size (n), statistical significance for the differences and degrees of freedom (d.f.) for the comparison between the values reported in this study versus those reported in the literature (left) or provided by large plantations (right) using unpaired two-tailed Student’s t-test. All variables were normally distributed (D’Agostino’s test; p > 0.30).
