Fertilization: basal dressing = 30 T manure / ha, 120 to 150 U of N / ha, 130 to 170 u P / ha, 130a 160 U K / ha; manure maintenance = 30 U 30 U of N and K before the last hoeing, iirigation = 4000m3 / ha
Fertilizer schedule
Watermelon Fertilizer Schedule
Use the stage cards as a planning checklist, then read country notes for local fertilizer language (rates are not prescriptions).
Stage checklist
Mix compost into the planting zone; avoid raw manure against roots.
Light, regular feeding for young trees/vines; mulch to conserve moisture.
Apply main nitrogen and balance P/K based on leaf/soil tests where possible.
Support potassium and calcium for fruit quality; do not push soft late growth before frost.
FAO fertilization notes
Excerpts from CropWhen calendar notes that mention fertilizer, manure, NPK, or related terms.
Irrigated. NPK application at the time of land prepararion. Harvest date indicate beginning date of harvesting, this process is continiously aproximately in duration of 1- 1,5 moth.
Rainfed. NPK application at the time of land prepararion. Harvest date indicate beginning date of harvesting, this process is continiously aproximately in duration of 1- 1,5 moth.
Irrigated. Autumn plaughing with organic manure application and NPK application at the time of land preparation. Under plastic tunnel cover during 40-50 days at beginning of vegetation.
The first harvest takes place 80jours after sowing and the last 100 jours.On generally direct seeding (1x1 m) on hill. The ririgation practiced in hill dry season (June-September or autajt times as needed). commonly apply organic manure.
Plowing planks. Sowing live pokets (3to 4 seeds), démmarriage retaining only two seeds. Application of organic manure during tillage and potash-rich fertilizer to chemical plantation.Traitement. Culture can be practiced all year for an pesticide treatment and regular watering.
Plowing planks. Sowing live pokets (3to 5 seeds) démmarrage retaining only two seeds. Application of organic manure during tillage and potash-rich fertilizer to chemical plantation.Traitement. Culture can be practiced all year for an pesticide treatment and regular watering.

FAQ: fertilizing Watermelon
When should I fertilize Watermelon?
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.
