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.
Excerpts from CropWhen calendar notes that mention fertilizer, manure, NPK, or related terms.
Irigation. PK fertilization at the time of land preparation. First nitrogen application has been applied at the beginning of tillering and secon is applied when plants started shooting stage.
Rainfed. Direct sowing after land preparation and NPK application at the time of planting
Reinfed. NPK fertilization at the time of land preparation. Second nitrogen application has been applied at the beginning of tillering stage
Mainly under rainfed conditions. Broadcast sowing. Ferilization: from 100 kg/ha to 150 Kg/ha of Nitrogen.
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.
