Fertilizer schedule
Use the stage cards as a planning checklist, then read country notes for local fertilizer language (rates are not prescriptions).
Work in compost or well-rotted manure; add a balanced basal dressing if soil tests low in P/K.
Band a light starter fertilizer near the row; avoid burning young roots with high-salt products.
Side-dress with nitrogen for leafy growth if leaves pale; water in thoroughly.
Shift toward potassium and steady moisture for fruiting vegetables (tomato, pepper, cucurbits).
Excerpts from CropWhen calendar notes that mention fertilizer, manure, NPK, or related terms.
The first harvest takes place 21 days after sowing and the last 65 days. generally made direct broadcast seeding (planting some to 20x20 cm) on hill and marshes. The ririgation practiced in hill dry season (June-September or as many times as needed). commonly applied organic manure and a little less of NPK
Crop grown mixed with other crops (polyculture). It is a culture starch source and solder starvation period. It does not apply fertilizer or manure
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.
