| Irrigation technology and water management are progresing in Proserpine, Mackay and Burdekin areas of Australia. Water application represents 15 per cent of the cost of cane production. Thus farmers are trying new equipment including the drip tape, the linear move and the centre pivot together with new irrigation scheduling tools. Measures have been taken to reudce significantly potential pollution hazard from surface run-off or irrigation tail water. Drip irrigation is gradually gaining ground in many cane producing countries. The high initial capital outlay coupled with rigorous management restrict further expansion of this system. Some studies are addressing the movement of water as well as root activity under drip irrigation. The major breakthrough for the overhead method is the centre pivot (or linear move) equipment. The lower investment cost and the less stringent management make this equipment more farmer-friendly. However, the application of chemicals including nutrients remains an unclear aspect of the equipment. Surface irrigation is improved through the surge flow technique or the use of lay-flat tubes with adjustable outlets. Inspite of t his, its water application efficiency remains low. Crop growth models and the introduction of new moisture monitoring equipment are contributing to increased water use efficiency. However, there are quite a number of issues that have been identified and which need the attention of equipment manufacturers as well as irrigation research scientists. | |
