  • Are there yield gaps in smallholder oil palm fields?
  • We assessed yield gaps in smallholder oil palm fields using a crop model, survey data, and field measurements. Average farmer yield was low, representing 42% of the attainable yield as determined by local weather and soil. Among management practices, nutrients, harvest interval, weeds control, and pruning have largest influence on yield gaps.
  • Does oil palm production have a large yield gap?
  • Our study adds value to these previous studies by showing the prevalence of large yield gaps across the oil palm production region in the country, using field-level data collected across many sites and years using consistent protocols, and rigorously screened to avoid biases due to reporting errors or inaccuracies in field size.
  • Can a model predict oil palm yield?
  • In response to this call for arms, this research developed an easily explainable and implementable model for forecasting monthly oil palm yield at the granular level of individual fields (30 ? 200 hectares) 12 months in advance of harvesting, with a demonstrated accuracy and consistency of 70% complying with the competition’s criteria.
  • How much oil does a palm plant produce a year?
  • Potential oil palm yields are >8 t oil ha ?1 year ?1 in most regions but average actual yields are about 3.3 t oil ha ?1 year ?1. Basic physiological processes underlying bunch production are not well understood. Water-limited yields are less than half of potential yields in drier growing regions of Thailand, Africa and the Americas.
