Propagation methods: vegetative propagation

1. Branch cutting (direct planting on land or
transplanting from nursery)

Root formation of cuttings with different
diameters (1,2 and 3cm) and lengths (15 and 30cm) show, that thicker cuttings form more roots than the thinner ones. Cuttings of 30cm. length developed more roots and their survival rate is higher than cuttings of 15cm. length. The following two factors are generally responsible for sprouting of the cuttings: the age of the plant from which cuttings are taken and the position of the cutting within the plant. Stalk/stem cutting method requires stems which are wooden already, or old branches which are 25 cm in length. The old branches are then cut about 50 cm off the ground. The cutting is planted in a poly bag (transplanting from nurseries) at a depth of 5 cm. Means used are, husk charcoal mixture and sawdust. After being planted, these means around the cutting are to be compacted.

2. Micro cutting propagation (in vitro)

The micro cutting methodology has a big advantage over the seedlings and branch cutting methodology. This methodology has a high exponential expanding character of the growth in size plantations and therefore plantations using seedlings methodology can never compete in growth with expanding plantations using the in vitro culture cutting method.Also the cost of a plantation will be lower than using the seedlings and branch cutting methodology, because more seeds will be available for crushing and therefore a faster return of investments will occur and more fertilizer will be available for the plantations. The costs of fertilizer will be reduced and even bring profit by selling it to the market. The more fertilizer can be used for the plantations, a higher amount of yield is achieved, which results into more profit. In-vitro culture is an alternative way in fast multiplying the plant. The method offers the biggest chance for producing a larger amount of seed plants in a relatively short time. The method can be done during the year, not relying on seasons. Besides, it is able to provide healthy and free of plant diseases plants over a longer period.
