Why Stevia?
Stevia (Stevia rebaudiana) is a plant native to South America, renowned for its sweet leaves. Its sweetness comes from compounds called steviol glycosides, which are 200-300 times sweeter than sugar yet calorie-free. With increasing demand for natural and healthy alternatives to sugar, stevia farming is a lucrative business opportunity for farmers and entrepreneurs.
Benefits of Stevia:
- Health Benefits:
- Zero calories.
- Safe for diabetics as it doesn’t raise blood sugar levels.
- Helps in weight management.
- Agricultural Benefits:
- Requires less water compared to sugarcane.
- Grows well in varied climates and soil types.
- Sustainable farming option with lower environmental impact.
Market Potential for Stevia
The global market for stevia is expanding rapidly. Here are some key trends:
- The demand for natural sweeteners has skyrocketed due to rising health consciousness.
- Major industries such as beverages, confectionery, and pharmaceuticals are incorporating stevia into their products.
- India, with its vast agricultural base, is emerging as a key player in stevia cultivation and exports.

Land Preparation for Stevia Farming
Proper land preparation is crucial for healthy stevia plants and a high yield. Here are the steps:
1. Site Selection:
- Climate: Stevia thrives in subtropical and tropical climates with temperatures between 15°C and 30°C.
- Sunlight: Requires full sunlight for optimal growth.
- Altitude: Grows well at altitudes between 200 to 500 meters above sea level.
2. Soil Requirements:
- Type: Loamy or sandy loam soil with good drainage.
- pH Level: Ideal pH is 6 to 7.5.
- Fertility: Enrich soil with organic matter such as compost or well-rotted manure.
3. Land Preparation Steps:
- Clear the Land: Remove weeds, rocks, and debris.
- Tilling: Plow the land to a depth of 30-40 cm for proper aeration.
- Levelling: Ensure the land is level to prevent waterlogging.
- Soil Testing: Conduct a soil test to check fertility and nutrient levels. Adjust pH and add fertilizers accordingly.
4. Irrigation Setup:
- Install a drip irrigation system for efficient water use and uniform moisture distribution.
Stevia Cultivation Process
Once the land is ready, follow these steps for stevia cultivation:
1. Planting:
- Propagation: Stevia is commonly propagated through stem cuttings or tissue culture. Avoid growing from seeds as it results in lower yield.
- Planting Time: Best planted during the onset of the monsoon (June-July) or in spring (February-March).
- Spacing: Maintain a spacing of 40 cm between rows and 20-25 cm between plants.
2. Watering:
- Stevia requires regular watering, especially during the initial growth stages. Use drip irrigation to maintain consistent moisture levels.
3. Fertilization:
- Use organic fertilizers like vermicompost or farmyard manure.
- Avoid over-fertilization, as it may affect the sweetness of the leaves.
4. Weed Control:
- Keep the field weed-free during the initial months to ensure proper plant growth.
- Use mulch to suppress weed growth and retain soil moisture.
5. Pest and Disease Management:
- Stevia is relatively pest-resistant. However, keep an eye out for common pests like aphids and leafhoppers.
- Use natural pesticides or neem oil to combat infestations.

Harvesting and Post-Harvest Processing
1. Harvesting:
- Timing: Stevia plants are ready for harvesting 3-4 months after planting.
- Method: Cut the stems 10 cm above the ground using a sharp knife or sickle.
- Frequency: Multiple harvests can be done in a year (3-4 times) depending on climatic conditions.
2. Drying:
- Spread the harvested leaves in a shaded, well-ventilated area for drying. Avoid direct sunlight to preserve sweetness.
3. Storage:
- Store dried leaves in airtight containers in a cool, dry place to maintain quality.
4. Processing:
- The dried leaves can be powdered and sold directly or extracted for steviol glycosides for industrial use.
Profitability of Stevia Farming
Initial Investment:
- Land preparation and irrigation setup.
- Purchase of stevia saplings or cuttings.
- Organic fertilizers and pest control measures.
Yield:
- One hectare of stevia can produce approximately 2,500–3,000 kg of dried leaves annually.
Market Price:
- Dried stevia leaves sell for around ₹500–1,200 per kg in the domestic market, depending on quality.
Revenue Potential:
- With proper management, farmers can earn profits ranging from ₹2–4 lakhs per hectare annually.
