Fertilizer schedule
Use the stage cards as a planning checklist, then read country notes for local fertilizer language (rates are not prescriptions).
Work in compost or well-rotted manure; add a balanced basal dressing if soil tests low in P/K.
Band a light starter fertilizer near the row; avoid burning young roots with high-salt products.
Side-dress with nitrogen for leafy growth if leaves pale; water in thoroughly.
Shift toward potassium and steady moisture for fruiting vegetables (tomato, pepper, cucurbits).

Cassava is grown on sandy clay soil without fertilizer. Only the rainfall is crucial for good production.
In modern culture: The cycle is a function of the Clones (6-12 months). The number of cuttings is lower per hectare and mineral fertilizer / ha to 200 kg 15.15.15, 100 to 200 kg of urea, 100 to 200 kg of potassium sulphate.
Traditional cultures: The cycle is a function of the Clones (6-12 months) Cultures are set up after a fallow and brûlies. The number of cuttings per hole ranges from three (3) to four (4) .No fertilizer organic or inorganic is used.

Follow the stage cards above (soil prep → planting → mid-season). Exact rates depend on soil tests and local packages — FAO notes below show how growers describe fertilization in different countries.
Treat them as historical/field guidance, not a prescription for your plot. Units and products differ by country. Confirm with agricultural extension before applying.
Not a fertilizer prescription. Over-application wastes money and can harm plants and waterways. Follow local extension packages.
