The fertilizer should be spread around the base of the plant and watered well to ensure that the nutrients are absorbed by the roots effectively.
Pruning Falcataria moluccana
Pruning is essential to maintain the overall health and shape of the plant. Proper pruning should be done during the rainy season annually. Dead and diseased branches should be removed, and new growth guided to provide a well-distributed canopy. The pruning should be done carefully and not too close to the trunk to avoid injuring the plant. Proper pruning ensures that the tree remains healthy and produces the desired shape and appearance.
Propagation of Falcataria moluccana (Miq.) Barneby & J.W.Grimes
Falcataria moluccana, also known as Moluccan sau, is a fast-growing tree species preferred for its timber, fuel, and pulpwood. Propagation of Falcataria moluccana can be achieved through three main methods: seeds, cuttings, and layering.
Propagation through Seeds
Seeds used for propagation should be collected from healthy mother trees and should be stored in cool, dry conditions to maintain their viability. The seeds can be sown directly on seedbeds or in polyethylene bags.
Sowing in polyethylene bags allows for easy transplanting when the seedlings are 4-6 months old. After the seeds have germinated, the polyethylene bags should be placed in an area with partial shade and watered regularly to keep the soil moist.
Raised seedbeds should be prepared by mixing sand and organic matter with the topsoil. The seeds should then be sown evenly and covered lightly with soil. The seedbeds should be watered regularly to keep the soil moist.
Propagation through Cuttings
The cuttings can be taken from stem tips or dormant buds in July or August during the rainy season. Hardwood cuttings are preferred and should have a diameter of 0.5-1.0 cm and a length of 20-30 cm.
The cuttings should be treated with a rooting hormone and planted in well-draining soil. The cuttings should be kept in partial shade and watered regularly to prevent wilting. After 3-4 months, the cuttings will sprout new leaves indicating successful rooting. The rooted cuttings can then be transplanted to containers or the field.
Propagation through Layering
Propagation through layering is preferred for Falcataria moluccana as it allows for faster production of planting material. The branches selected for layering should be mature and healthy with a diameter of 2-4 cm. The branches should be bent towards the ground and a shallow groove made on the underside of the bent branch. The groove should be treated with a rooting hormone.
The bent branch should be secured to the ground using pegs or stones and covered with soil. The soil layer should be kept moist, and after 3-4 months, roots will form at the groove. The rooted layer can then be separated from the mother plant and transplanted to containers or the field.
