Sugarcane Farming

Why 6 months? Because that is one real production cycle for sugarcane farming. You study each month's material while your own operation (or your planning) goes through exactly that stage. By graduation you have either harvested/sold your first production or hold a complete, costed plan ready for funding.

Structure: 6 monthly modules → lessons → practical assignments → a 10-question quiz each month → final business project.

How to study (hybrid): Online — work through each month on your phone, log sessions in the Study Diary, ask the rAs AI assistant anything. Offline — save this page and do the practicals in the real world.

• Saccharum officinarum: tropical grass for sugar and biofuel
• Climate: 15–30°C; 1,500–2,500mm rainfall (more = higher yield)
• Soil: fertile, well-drained, pH 6–7.5; avoid waterlogging
• Cycle: 12–24 months seed-to-harvest (fast compared to other crops)
• Ratoon cropping: cut cane regrows 4–6 times from roots
• Calculate: 1 hectare yields 60–80 tonnes fresh cane (12 tonnes sugar)

• Varieties: bred for sugar content (14–18% Brix)
• Disease resistance: select against smut, rust, wilt
• Seed source: healthy, disease-free cane setts (40cm segments)
• Seedbed treatment: fungicide + insecticide dip (prevent rot)
• Planting rate: 20,000–25,000 setts/hectare
• Calculate: seed cane cost = $200–400/hectare

• Deep ploughing: 40cm+ to break hardpan
• Compost/manure: 20–30 tonnes/hectare
• Lime: if pH < 6 (add 2–4 tonnes/hectare)
• Planting: furrows 50–60cm apart; setts touching
• Mulch: trash (previous harvest) reduces weed pressure
• Calculate: field preparation costs $300–500/hectare

• Sprouting: 2–3 weeks at 20–25°C (moisture critical)
• Emergence: tillers (shoots) form from sett nodes
• Canopy coverage: 120–150 days to full cover
• Irrigation: germination phase = 80% of water need
• Weed control: first 90 days critical (inter-row cultivation)
• Calculate: water cost $200–500/hectare in dry regions

• Sugarcane borer: moth larvae inside stalks (major threat)
• Smut: fungal disease (black sooty growth on stalks)
• Rust: orange pustules (leaf symptoms); reduce yield 10–15%
• Wilt: vascular disease; no cure (rotate fields)
• Organic control: sanitation, cultural practices, beneficial insects
• Calculate: chemical control = $100–200/hectare; organic = labour-intensive

• Growth slows; stalks elongate and harden
• Nitrogen uptake complete; sugar accumulates
• Moisture stress (slight) increases sugar (stress ripening)
• Stalk wall thickens; internodes fill with juice
• Brix testing: 12–16% optimal (test weekly near harvest)
• Calculate: yield peaks 12–18 months; delayed harvest = sugar loss

• Harvest window: 6–8 weeks (sugar stable in stalk)
• Manual: cut cane 10cm above ground, remove leaves, bundle
• Mechanical: chopper harvester (where available)
• Transport: 24–48 hours max (juice quality deteriorates)
• Queuing: crushing delays = juice fermentation = sugar loss
• Calculate: 10 tonnes/hectare = 200+ bundles to transport daily

• Crushing: extract juice (extraction rate 70–85%)
• Juice processing: heating, clarification, evaporation
• Crystallisation: concentrate juice; grow crystals
• Centrifuge: separate crystals from molasses
• Grades: white (refined), raw (brown), muscovado (moist)
• Calculate: 10 tonnes cane = 1 tonne raw sugar (12% extraction)
