Measuring potential yield

Potential yield can be measured using
1. Crop growth simulation models (e.g., ORYZA2000)

Using these models requires site-specific data and rigorous validation, and is still to be refined for Southeast Asia.

2. Experiment yields

Using experiment yields to measure potential yield requires well-managed field studies in which yield-limiting and yield-reducing factors are eliminated.

3. Best farmers’ yields—upper 10 percentile per season + year

The challenge in using best farmers’ yields to measure potential yield is that it is difficult to know if all abiotic and biotic stresses were avoided.
