Fertilizer schedule
Use the stage cards as a planning checklist, then read country notes for local fertilizer language (rates are not prescriptions).
Apply basal NPK according to local recommendations; incorporate residues or manure where available.
Place starter phosphate near the seed row when soils are cold or low in P.
Top-dress nitrogen in one or two splits if the crop looks N-hungry; avoid late N that delays maturity.
Only apply late N when grain protein or yield response is expected; follow extension rates.

Irigation. Direct sowing after land preparation and NPK application at the time of planting. Second nitrogen application at the booting stage
NPK fertilizers are apliques in bunches at planting at a spacing of 75 x 50 cm. irrigation possibility in case of dry periods
Unirrigated, manual labor and animal power, Half live, usually monoculture and sometimes in association with peanuts, spreading chemical fertilizer. Existence of mechanized plantations.
Not irrigated, plowed manue flat, Half live, usually in mixed culture with beans or peanuts, organic fertilizer. Spreading of fertilizer for mechanized monoculture. In rotation with legumes and vegetables.
Not irrigated dishes manual labor and animal power, Half live, usually in mixed culture with beans or peanuts, organic fertilizer. This second season is usually consumed fresh.
Not irrigated, plowed ridges manual and animal traction, Half live, usually in mixed culture with beans or peanuts, spreading organic fertilizer. manual weeding. Spreading of fertilizer for mechanized monoculture with herbicide use. In rotation with legumes and vegetables.
Not irrigated, plowed flat manual and animal traction, Half live, usually in mixed culture with beans or peanuts, manual weeding, fertilizing organic. Spreading of fertilizer for mechanized monoculture with use of herbices. In rotation with legumes and vegetables.
Unirrigated, manual labor and animal power, Half live, usually in mixed culture with beans or peanuts, organic fertilizer. Spreading of fertilizer for mechanized monoculture. In rotation with beans and vegetables.
Unirrigated, plowing animalle traction in rotation with cotton cultivation, semi-direct, usually monoculture spreading chemical fertilizer.
Traditional irrigation and drip irrigation. The plupatrie production is for fresh consumption. Organic and mineral fertilizers during site preparation and mineral (NPK) covering.
Dryland rainfed. The major part of the seed needs are covered by domestic production. Most seedlings are made associated with dry beans and an insignificant part is done after dark rainy. Rainfed no fertilizer application
corn fresh harvested early and adjusts the welding problem. It is sown around the boxes. They bring compost to soil preparation.
Second season organic matter is applied before planting and NPK is applied during planting
Irrigation, direct seeding, NP fertilizer application at planting and after 30days
Rainfed, direct sowing, NP fertilizer application at planting
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.
