Stage checklist

Soil preparation
Before sowing

Apply basal NPK according to local recommendations; incorporate residues or manure where available.

At planting
Sowing

Place starter phosphate near the seed row when soils are cold or low in P.

Tillering
Early tillering / knee-high

Top-dress nitrogen in one or two splits if the crop looks N-hungry; avoid late N that delays maturity.

Heading
Boot to heading (as advised locally)

Only apply late N when grain protein or yield response is expected; follow extension rates.

driving irrigated: need = 4000m3 / ha- stand = 180000-200000 plants / ha-Fertilization: 100U Phosphorus 90 U K / ha before sowing: 66 U nitrogen at planting and 33 U nitrogen before flowering

Algeria Sublittoral East and Central

Azerbaijan North Coast Plain areas

Irigation. Direct sowing after land preparation and NPK application at the time of planting. Second nitrogen application at the booting stage

Azerbaijan North Coast Plain areas

Irigation. Organic fertilizer application at the land preparation. Direct sowing after land preparation and NPK application at the time of planting.

Burundi Lows Northeast and East

There is no appique iirgation is not applying fertilizer. The spacing is 75 x 50 cm. Sorghum succeeds généralemen beans

Cameroon Sudano-Sahelian zone

Unirrigated, manual labor and animal power, Half live, usually no fertilizer. In rotation with cotton.

Cameroon Sudano-Sahelian zone

Requires the nursery. Transplanting after 20 to 25 days on mayo beds (rivers) desiccated. No fertilizers or chemical treatment.

Chad Sahelian Zone

The intermediate cycle in this area is already considered long cycle and hardly successful. Sorghum is always grown without fertilizers.

Rainfed, direct sowing NP fertilizer applied at planting and knee height

Ethiopia Arid agro ecology (Hot to warm lowland plains and tepid to cool mid highlands)

Irrigation, dierect sowing NP fertilizer applied at planting and at knee height

FAQ: fertilizing Sorghum

When should I fertilize Sorghum?

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.

Can I copy NPK numbers from the notes?

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.
