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).

Direct sowing - harvesting bulb-Fertilization base 60a = 80 U of N / ha, 100 to 120 U P / ha, 180 to 200 U K / ha; Manure maintenance u = 45 N and 50 U of K / ha
Irrigated. Autumn plaughing and organic manure application at the time of land preparation, NPK application at the time of seed sowing.

growing area by excellence in Chad, onions produced in this area are sold throughout the country. Site selection and soil preparation are crucial to the success of the production. We buried compost before transplanting.
Irrigation. Requires time nursery: 40 - 50 days. Organic fertilizers or minerals applied when soil preparation. Proceed mulching boards subcultured
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.
