• Cuttings are planted at 60 X 30 cm distance keeping the end buds exposed.
• Roots are formed in buried portion of cuttings. Vine cuttings are planted during June – July.

Propagation through sprouts:-

• For producing planting materials (sprouts) from tubers two nurseries are needed namely primary nursery and secondary nursery.
