🎋 Sugarcane Yield Calculator (Tropical & Subtropical)

Estimate sugarcane yield, total production, sugar recovery, and estimated mill revenue using stalk density, stalk weight, sucrose content, and field losses. Based on FAO sugarcane production guidelines.

Enter area, effective stalks per meter, average stalk weight, sucrose percentage, field loss, and mill price to estimate cane yield, total production, sugar output, and expected revenue.

🧮 Formula & How It Works

Stalks per Hectare = (Stalks per Meter ÷ Row Spacing) × 10,000 m²/ha

Gross Cane Yield = Stalks/ha × Stalk Weight (kg) ÷ 1000 (kg→t)

Adjusted Yield = Gross Yield × (1 − Field Loss%)

Sugar Yield = Cane Yield × Sucrose% × Recovery Factor (~0.85)

Mill Revenue = Total Tons Cane × Mill Price per Ton

📊 Calculation Example

1 ha with 8 stalks/m row, 1.2 kg/stalk, 1.5 m spacing, 13% sucrose, 5% loss: Stalks/ha = (8 ÷ 1.5) × 10,000 = 53,333 stalks/ha. Gross yield = 53,333 × 1.2 ÷ 1000 = 64.0 t/ha. Adjusted = 64.0 × 0.95 = 60.8 t/ha. Sugar = 60.8 × 0.13 × 0.85 = 6.72 tons sugar. Revenue at $35/t: 60.8 × 1 × $35 = $2,128.

📖 How to Use This Calculator

1. Measure row spacing in your field. 2. Count effective stalks in a 5-meter row segment at 5-10 random spots and divide by 5. 3. Harvest and weigh 10-20 representative stalks to get average stalk weight. 4. Use Brix or lab sucrose reading. 5. Estimate field loss (trash, tops, lodging). 6. Enter current mill price. Calculate.

🎋 About This Tool

Sugarcane is a major tropical and subtropical crop grown for sugar and ethanol. Global average yields are 60-70 t/ha; irrigated high-input systems can reach 100-150 t/ha. Sugar recovery typically ranges 10-14% by weight. Major producers: Brazil, India, Thailand, China, Australia. The formula follows FAO Sugarcane Production Guidelines and USDA Economic Research Service sugar sector reports.

⚠️ Common Mistakes & Tips

Counting non-productive stalks. Using green weight without drying correction. Forgetting tops and trash (10-15% of total). Row spacing errors dramatically affect stalk density calculations. Sucrose varies by variety, age, and season — sample at harvest time.

❓ Frequently Asked Questions

What is a good sugarcane yield? ▼

Global average is 60-70 t/ha. Commercial irrigated farms in Brazil, Australia, and Louisiana achieve 80-120 t/ha. Smallholder rainfed farms may yield 30-50 t/ha. High-yielding varieties under optimal conditions can exceed 150 t/ha.

How is sugar recovery calculated? ▼

Sugar recovery = Cane tonnage × Sucrose% × Recovery factor (typically 0.85). This accounts for milling efficiency, molasses loss, and trash. A 100 t/ha cane crop at 13% sucrose yields about 11 tons of commercial sugar.

What affects sugarcane yield the most? ▼

Water availability (1500-2500 mm seasonal), nitrogen fertilizer (150-250 kg N/ha), variety selection, row spacing, and harvest timing. Drought reduces yield 30-50%; adequate irrigation is the single biggest yield driver.

How does the mill price work? ▼

Mill prices vary by country and are often tied to sugar futures (NYSE: CANE) plus local adjustments. Brazil: ~$25-40/t. Australia: ~$35-50/t. India: state-advised FRP (Fair & Remunerative Price). Thailand: government-set price per tonne cane.

How do I use the Sugarcane Yield Calculator correctly? ▼

Start by gathering accurate field measurements: row spacing, stalk count per linear meter, and average stalk weight. Use a refractometer or lab Brix reading for sucrose. Estimate realistic field loss. Enter your local mill price. Review results against regional averages.
