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).

The first harvest takes place 120 days after sowing and the last 150 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. More adapted to the Frèche season, despite there are a variety that can be grown all the year round. Sowing in Pepinere with transplantation field 30-40 days after sowing. organic fertilization and mineral in preparing the land and mineral cover.
Sowing date includes time of seed sowing in the nursery. Seedlings will grown in the nursery during 30-40 days befor field replantation. Irrigated. Autumn ploughing with organic manure application. NPK application at the time of field plantation.
Sown in nursery; seedlings transplanted when 30-42 days old; NPK fertilization in nursery and at transplanting; application of well-aged animal/poultry manure during land preparation; NPK application every 3 weeks after transplanting; irrigate once per week; commonly grown variety is Formoso F1. A cash crop mostly grown by smallscale and emergent farmers in and around urban and peri-urban areas.
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.
