Other claims from this paper (6)
- Recommendation Simulations with gridded weather databases should be validated against simulated yields based on station weather data.
- Recommendation Site-specific yield validation remains necessary and should be carried out every 5 to 10 years.
- Observation Comparing actual yield with the best yield in comparable conditions can be biased where best management practices are not feasible, and modelled yields then give more relevant benchmarks.
- Observation Remote sensing applied to yield gap analysis has improved over recent years, mainly through pixel-based biomass production models.
- Observation The accuracy of yield gap estimates is determined by the quality of sub-national actual yield data.
- Observation The gap between potential and water-limited yield indicates yield gap that can be removed with irrigation.
