D. aA computerized model for evaluating irrigation schemes for sugarcane. c1986 aA computerized model has been prepared to enable estimates to be made of sugarcane yields when a given amount of irrigation water is used. The input data comprise daily rainfall records for as long a period as possible, average monthly class A pan evaporation figures, and a proposed sequence of planting and harvesting of the crops which comprise a full crop cycle. The monthly increase in green leaf canopy also needs to be estimated. The programme permits the variation of parameters such as total available soil moisture, irrigation efficiency, application rate and an evapotranspiration model. It indicates, for each year and on average, the rainfall efficiency, the number of days spent irrigating, and the number of days during which the crop was subjected to various degrees of stress. airrigation asugarcane aComputador aInformática aIrrigação aSimulação aCana-de-açúcar aComputer aSimulation1 aHARDING, R.
