Mangoes can be grown in a variety of climates and are adaptable to different patterns of seasonality. The timing of key processes is determined by the climate, so understanding these regionally specific differences is the key to production management. Mangoes are grown in tropical, arid, desert and temperate climates across Australia.
Table 1. Types of climates where mangoes are grown in Australia and the corresponding irrigation requirement.
|Climate region||Irrigation requirement|
|Wet/dry tropics||Will not usually require irrigation during the wet summer season. Rainfall during this time is usually sufficient to allow tree growth and fertiliser uptake after the harvest period. Will require irrigation in the dry season to enable bud growth for flowering and subsequent fruit development.|
|Temperate||May require irrigation all year round, although should be managed depending upon rainfall.|
|Arid/Desert||It will require irrigation all year round.|
Water stress is a complicated topic in an irrigated crop. A lack of rainfall can trigger agricultural drought situations, as can poor irrigation management, high temperatures and/or low humidity creating increased plant water demand.
Some reference terms or critical factors that influence plant water stress and irrigation include:
Efficient crop water use and high yield potentials can only be achieved if the agronomic factors such as nutrition, disease and pest management are also optimised.
