Saccharum officinarum
About Sugarcane
Sugarcane is the world's largest crop by production volume (1.9 billion tonnes annually) and the source of 80% of the world's sugar. Brazil and India together produce 60% of global output. Sugarcane is also the leading feedstock for bioethanol — Brazil's sugarcane ethanol program is the world's most successful biofuel initiative. The crop is a giant tropical grass growing 3-6 m tall, harvested 10-18 months after planting. Multiple ratoon (regrowth) harvests reduce replanting costs. Sugarcane is critical to the economies of many developing countries, employing millions of workers. It is propagated vegetatively through stem cuttings (setts).
Growing Conditions
Full sun — one of the highest solar radiation requirements of any crop
1,500-2,500 mm per crop. High water demand especially during grand growth phase (3-9 months).
Deep, fertile, well-drained loam. pH 5.5-7.5. Tolerates wide range of soil types.
Optimal 30-35°C for growth. Night temperatures of 15-20°C promote sucrose accumulation before harvest.
High humidity promotes growth but low humidity during ripening increases sugar content.
Tropical — 10-18 months for plant crop. Ratoon crops harvested at 12-month intervals.
Step-by-Step Growing Tips
Use disease-free seed cane from certified nurseries
Hot water treat setts at 52°C for 30 minutes before planting
Plant 3-bud setts end-to-end in furrows 90-120 cm apart
Earthing up at 3-4 months supports root development and prevents lodging
Withhold irrigation 3-4 weeks before harvest to concentrate sucrose
Deliver cut cane to mill within 24 hours to prevent sucrose inversion
