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).

Sowing date includes time of seed sowing in the nursery. Seedlings will grown in the nursery during 30-40 days befor field replantation. Irrigated. NPK application at the time of field plantation.
The first harvest takes place 80 days after sowing and the last 100 days. generally makes transplanting (50x50cm) on hill and marshes. The ririgation practiced in hill dry season (June-September or autajt times as needed). commonly applied organic manure and a little less of NPK
Culture dryland rainfed and / or semi-irrigated. Sowing in nursery before the rains (with irrigation). organic and mineral fertilization (NPK + Urea) applied when the soil preparation. Using earlier varieties.
Traditional irrigation and drip irrigation. She prefers Frèche season. Seedling Nursery with transplant 25-30 dias after sowing. organic and mineral fertilization when preparing terrain and minéralle (NPK + Urea) covering.
Begins after the rains. Contribution of composts. The plants are produced in the nursery before being planted.
Begins after the rains. Grown on boards with exposed contribution of composts. The plants are produced in the nursery before being planted.
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.
