Black potatoes (Purvasuka) are becoming a profitable crop for farmers, agronomists, and agricultural entrepreneurs. With a short harvest period of just 3.5 to 4 months and stable market prices ranging from ₹10,000 to ₹30,000 per kilogram, this variety offers a high return on investment. Additionally, its distinct flavor and premium market value make it an attractive choice for commercial cultivation.
However, achieving high yields requires precise agronomic practices. Neglecting proper care can lead to nutrient competition from weeds, stunted growth, and disappointing harvests. Below are the key cultivation techniques for maximizing black potato production:
1. Soil Loosening and Hilling
- Loosening the soil improves aeration and drainage, promoting healthy tuber development.
- Hilling (mounding soil around the base of plants) prevents greening of tubers and enhances root growth.
2. Timely Fertilization (1–2 Months After Planting)
- Apply balanced fertilizers (NPK) during the early growth stage to support vigorous plant development.
- Organic amendments like compost or vermicompost can enhance soil fertility and microbial activity.
3. Weed Management (After 2 Months)
- Weeds compete for nutrients, light, and water, reducing yields by 20–40% if uncontrolled (FAO, 2023).
- Manual weeding or mulching helps maintain soil moisture and nutrient availability.
4. Optimal Harvesting (3.5–4 Months)
- Harvesting too early reduces tuber size, while delaying can increase disease risks.
- Studies show that properly managed black potato farms achieve 30–50% higher yields compared to neglected fields (Journal of Agronomy, 2024).
Black potato farming offers a short-cycle, high-income opportunity, but success depends on meticulous soil care, fertilization, and weed control. By following these best practices, farmers can maximize both yield and profitability while meeting the growing demand for this premium crop.
