Fertilizer schedule

Cowpea Fertilizer Schedule

Use the stage cards as a planning checklist, then read country notes for local fertilizer language (rates are not prescriptions).

Stage checklist

Soil preparation
Before sowing

Inoculate seed with rhizobia when needed; supply phosphorus and potassium — legumes often need less N.

At planting
Sowing

Use a low-N starter if soils are very poor; excess N reduces nodulation.

Flowering / pod set
Pre-flower to early pod

Maintain K and micronutrients (e.g. Mo, B where deficient); irrigate to reduce flower drop.

FAO fertilization notes

Excerpts from CropWhen calendar notes that mention fertilizer, manure, NPK, or related terms.

Cameroon High West plateaux

Ridge tillage. Practiced in rotation with maize. Monoculture with chemical treatment. No mineral fertilizer application.

Cameroon Sudano-Sahelian zone

Ridge tillage. Practiced in rotation with sorghum or corn. Monoculture with chemical treatment. No mineral fertilizer application.

Cape Verde Areas sub-humid and wet altitude

Dryland rainfed. The major part of the seed needs are covered by domestic production. Sowing associated with dry corn or after dark and the storm pluies.En no fertilizer application

Cote d'Ivoire

Direct seeding Organic fertilizers and minerals applied when soil preparation Harvest: Once a week Harvest time: 20 days

Gabon Area: Class, Center, East, South East and West, South

Cowpea is little grown in Gabon.Le seeding is done at a density 0.4 x 0.4 m planting hole 2 seeds. A low mineral fertilization of the order of 30 to 50 kg / ha of complete fertilizer is applied. In humid tropics cowpea is very susceptible to fungal diseases (Fusarium, Sigatoka ...)

Guinea Forest Area

Not irrigated Sémi live without fertilization

Kenya Upper midland zone 4 (UM4)

Rainfed. Fertilizer rarely applied, if any, organic fertilizer by broadcasting

Kyrgyzstan South-East Uplands

Irrigated. Oganic manure application at the time of lnd preparation and PK application at the time of sowing.

FAQ: fertilizing Cowpea

When should I fertilize Cowpea?

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.
