Sorghum Fertilizer Schedule
Use the stage cards as a planning checklist, then read country notes for local fertilizer language (rates are not prescriptions).
Stage checklist
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
Irigation. Organic fertilizer application at the land preparation. Direct sowing after land preparation and NPK application at the time of planting.
There is no appique iirgation is not applying fertilizer. The spacing is 75 x 50 cm. Sorghum succeeds généralemen beans
Unirrigated, manual labor and animal power, Half live, usually no fertilizer. In rotation with cotton.
Requires the nursery. Transplanting after 20 to 25 days on mayo beds (rivers) desiccated. No fertilizers or chemical treatment.
The intermediate cycle in this area is already considered long cycle and hardly successful. Sorghum is always grown without fertilizers.
Not irrigated, fertilized No
Rainfed, direct sowing NP fertilizer applied at planting and knee height
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.
