Assumptions, fit-shortfall, and next checks
A representative centroid and regional climate window cannot establish parcel soil, water access, elevation, infrastructure, labour, contracts, or local farm-gate economics. Use this page to identify the next question, then verify local evidence before committing capital.
Market Demand — Onion
Global consumption & trade · FAO 2010–2023Is Onion viable in Ghana?
Onion is not typically viable in Ghana: growing-season temperatures (~29.3°C) run well above its 12–25°C optimum. Onion (Vegetables, annual) performs best around 12 - 25 °C with a seasonal water requirement of 350 mm / season. Run a coordinate-level audit for mapped field-level estimates and local risk context.
Growing Onion in Ghana: what to expect
Ghana is wetter (~1356 mm/yr) than Onion's ~350 mm need — prioritise good drainage to avoid waterlogging and root disease. Onion can be established year-round in Ghana's frost-free climate, ideally at the start of the wet season.
