Can canopy management increase quality fruit production in Syzygium cumini (L.) Skeels?

Abstract

With high density plantings becoming increasingly popular, a need has developed for pruning techniques and cultivars supporting this cultivation method. Central leader pruning is well suited for high density planting as it enables greater space utilisation. After studying a Maluma orchard on Allesbeste, Limpopo, South Africa, Maluma has been identified as a cultivar that is well suited for central leader pruning methods. Maluma, a less vigorous, precocious and productive early bearing Hass-like cultivar, is characterised by a visible natural central leader, with prominent lateral branching ( ≥ 90º angle). The pruning of trees planted in the field should commence during the first year from planting. The pruning method implies the selection of the strongest vertical shoot as your central leader, then removing all other vertical growth, which leaves you with pyramid-shaped trees. The sylleptic growth habit of Maluma supports this pruning technique which results in highly productive lateral branches. This pruning method increases light penetration and supports the moving of the volumetric production capacity of the tree closer to the ground, utilising space better as well as enabling picking to be done faster and more efficiently. The production capabilities of high density planting is tremendous as the surface area planted is being utilised better. Most farmers are cautious to commit to high density plantings as pruning is seen as a mammoth task. However in this study it is illustrated that with the supportive characteristics of Maluma, high density plantings are a viable option lowering input costs without sacrificing productivity.

“…These oils are used in everything from food production and cosmetics to medicines and pesticides. Species such as guava (Psidium guajava), rose apple (S. jambos), wax apple (S. samargarense) and jamun (S. cumini) are important horticultural species cultivated in tropical regions for their fruit [37][38][39].…”
