Methodology
Descriptive dimensions (family, lifecycle, associated diseases/pests, soils) are read from each crop’s reference entry. No crop is ranked as “better”; agronomic outcomes are region- and system-specific.
Limitations
- Descriptive comparison only — not a yield, profitability, or suitability ranking.
- Associated diseases/pests and soils are typical, not exhaustive, and vary by region.
