Orchard productivity is directly related to the establishment and maintenance of an effective canopy. Productivity of the orchard canopy is limited by factors such as: scion and rootstock combinations; planting density; production systems; and climatic and edaphic factors.

Once established, the orchard's canopy management reflects an interpretation of the physiology underlying the relationship between vegetative growth and cropping. Canopy management is manipulated through: pruning and training; irrigation and nutrition; growth regulator application, and environmental modification.

These avenues are available to overcome deficiencies in the original orchard design. Aspects of irrigation, growth regulator usage and the use of protective structures were discussed.
