MANGO CULTIVAR AND HEDGEROW EVALUATION - CARNARVON, WESTERN AUSTRALIA |
| Author: | A.T. Muller |
| Abstract:
Carnarvon (24°53'S, 113°39'E) is currently the main area for growing mangoes in Western Australia (Muller and Burt, 1989). A Department of Agriculture survey in 1988 showed 7635 producing and 4758 non-producing trees. The main cultivar, Kensington Pride produces trees which grow to a height of 10–15 metres at maturity making harvesting and other management activities difficult and expensive. Trees are usually planted 6m x 6m and thinned to 6m x 12m or a similar spacing as required by year 12. In May 1986, a Mango cultivar hedgerow trial was planted at Carnarvon to evaluate thirteen cultivars, using close planting (6m x 2.5m) and mechanical hedging. The trees were established with drip irrigation and converted to sprinklers in July 1988. Flowering commenced in July 1988, 2 years after planting. Harvesting commenced on 13 December, 1988 with the cultivar Glen and concluded on 15 March, 1989 with the cultivar Brooks. Highest yielding cultivars were Brooks, Sensation, Bangalora and Davis-Haden. The calculated yield per hectare shows the potential high returns that could be achieved within 3 years using a high density planting. Mechanical hedging has not been carried out and may not be required with some of the small precocious cultivars such as Irwin and Sensation. | |
