Abstract
Growers who irrigate need to answer three questions throughout the growing season — (i) when should each field be irrigated; (ii) how much water should be applied; and (iii) which field should be irrigated first. An heuristic solution procedure has been developed to produce realistic irrigation schedules, within a practical time, for growers using hosereel-raingun irrigators. The financial implications of the irrigation schedules are analysed over a short term period (typically 7 days). The constraints are limited availability of equipment, labour and/or water. Use of the model is illustrated with a common situation faced by a U.K. grower.
