Notes:

Maximum attainable yields represent dry weight yields, which have been estimated with climate data of Kumasi meteorological station.
The yields presented for annual crops assume that required fallow requirements are respected. As a rule of thump for (low / intermediate) level input and management conditions fallow requirements may vary between (30–90% / 15–40%) depending on crops grown, soil nutrient availability, soil nutrient retention capacity and climatic conditions. This means that long-term sustainable yields would be in the same order (30–90% / 15–40%) lower than indicated in the Table above for low inputs.
Yields presented for perennials, require adjustment for rotation requirements
Not suitable includes 9,339 km2 waterbodies and 5,624 km2 unsurveyed areas
