1. Weeding and ridging
After crop establishment, further cultivation may be undertaken to control weeds, or to reform ridges (hill up) after fertilizer side dressing or to prevent weevil infestation. Weeding is done every time it is deemed necessary. However, disturbance of soil in the ridges should be minimized to avoid root damage.
2. Fertilization
The farmer uses organic farm yard manure to grow the tubers. However, in cases where inorganic fertiliser has to be used, phosphorus and potassium-based fertiliser are applied. Nitrogen-based fertiliser is discouraged as it enhances growth of leaves, neglecting the tubers.
