Thinning

Hand thinning is done soon after the germination. Thinning is necessary to have root tubers of uniform shape and size by providing optimum space for uniform development of the root.

Manuring

Apply FYM 20 t/ha as basal. N:P2O5:K2O 75:37.5:37.5 kg/ha is recommended. Full dose of P2O5 and K2O and half dose of N are applied as basal. Remaining half dose of nitrogen is applied as topdressing when the plant starts growing vigorously.

Irrigation

It is necessary that enough soil moisture is available to help uniform seed germination and growth of plant. Give a light irrigation soon after seed sowing to ensure good germination. The crop should be irrigated at an interval of 4-5 days in summer and 10-12 days in winter.

Weed control

Weeding should be done at regular intervals to keep down the weeds. Manual weeding is commonly practiced. Avoid deep cultivation as it may damage the crop.

Earthing up

Earthling up is done to support the structure of the plant and to prevent the exposure of roots to sunlight. Earthing up should be done, when the root starts growing. Shallow hoeing is necessary to facilitate better root growth.
