Deep ploughing with a harrow every 2-3 weeks helps keep the soil in optimal condition and prohibits hard pans. Sweet potatoes prefer nutrient-rich earth. Therefore, application of organic compost or animal manure during the ploughing phase is recommended as it acts as a feeder to the soil, promoting growth and yield of the crop.

Stage Two: Seed Selection and Planting

Property harvested roots or slips of sweet potatoes are ideal for replanting. Seed selection and planting process are the key factors influencing the final yield.

Choosing disease-resistant, fresh sweet potatoes or certified slips for replanting is critical. Old or sprouting tubers must be excluded. The planting process should be carried out with care. The slips should be planted 3 to 4 inches deep, keeping them spaced 12 to 18 inches apart to aid in easy tuber growth and farming operations.

Stage Three: Management of Pests and Disease Control

Like all crops, sweet potatoes too are vulnerable to disease and pest attacks. Effective detection and control measures need to be in place to protect the crop yield.

Some of the commonplace pests are wireworms, sweet potato weevils, and white grubs. Utilizing bio-pesticides and encouraging natural predators can prove effective in controlling these pests. Regular monitoring of the crop is essential for early detection and management of infestations. Similarly, disease control is vital as sweet potatoes can suffer from fungal, bacterial, and viral infections. Practices like annual crop rotation, consistent cleaning of farming tools, and use of disease-resistant varieties can help control the spread of diseases.

Stage Four: Harvesting and Post-Harvest Handling

The joy of a promising harvest appears within 90 to 170 days post-planting varying with the type and growing conditions.

The harvest should be carried out gently to prevent any damage to the tubers, which can cause rot.
