About Sugarcane nutrition
Sugarcane is a long-duration crop (about 10-18 months) that removes large amounts of nitrogen and potassium from the soil. Split applications timed to tillering and grand growth, plus zinc and iron where deficient, improve cane weight and sugar recovery.
- Climate
- Tropical and subtropical climate, about 20-35 °C for growth, with a cooler, dry spell before harvest for sugar build-up.
- Soil
- Deep, well-drained loam to clay loam, pH around 6.5-7.5.
Stage-wise nutrient management for Sugarcane
What the crop needs most at each growth stage.
Germination
Phosphorus and organic manure in furrows for sett germination and roots.
Tillering
Nitrogen in splits with zinc for more tillers.
Grand growth
Nitrogen and potassium for cane elongation and weight.
Maturity
Potassium for sugar accumulation; stop nitrogen well before harvest.
