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).

Irrigated but may be carried out dry for the cultivation of winter-fertilization background = 20à30T manure / ha, 70 U of N / ha, 60-80 U P / ha, 80-100 U of K / ha; manure maintenance = 30 U N / ha and 50 U of K / ha after thinning-Requirement = 3500-4000M3 water / ha
Irrigated. Organic manure and NPK application at the period of land preparation. Second application of nitrogen fertilizer at the time of seedlings.
The first harvest is 60 days after sowing and the last 80 jours.On is usually direct seeding (30x15 cm) hill (June-September or autajt times as needed). The ririgation practiced in hill dry season. commonly apply organic manure.
Manual labor or animal plank traction. till. Thinning the lifting. Application of organic fertilizer well decomposed when plowing planting fertilizer minerals, chemical treatments. Culture can be practiced all year for an pesticide treatment and regular watering.

Here also its culture begins after the rains. Contribution of composts. The plants are produced in the nursery before being planted.
Culture begins after the rains. The turnip is grown on plates exposed with added composted. The plants are produced in the nursery before being planted.
As basal fertilizer, provide from 15 to 25 kg of organic matter well decomposed and 300 g of mineral fertilizer (15-15-15) to a board of 10 m². Stir by digging. 15 to 20 days after seeding, provide 200 g of mineral fertilizer (15-15-15) to a board of 10 m² as manure maintenance.
Distance between the rows should be 24 to 28 inches. Distance between the plants should be 2.5 to 3.2 inches. Farm yard manure should be given 15 tonnes per acre, nitrogen 20 Kg/acre, phosphorus 20 Kg/acre, Pottash 25 Kg/acre should be applied.
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.
