i. Bud grafting : This is done by the insertion of a strip bark containing a bud from high yielding clones under the bark of young seedling about 5cm high till they become united in 3 to 4 weeks. Then the old seedling stem is sawn off above the grafted bud.
ii. Ratooning ; It is a process by which the cane is cut close to the ground where the sugar content is concentrated. After that the remaining stem begins to grow again and produces the second crop called ratoon.
iii. Transplantation : In this the sowing of seeds is usually done in well -prepared seed beds known as nurseries at the beginning of the monsoons. In about 4 weeks time when the plants are 15 to 20 cm tall they are carefully unrooted in bunches and replanted in the floded fields.
