How it works
After registration, growers enter key data about their crops. These are combined with weather data (current season and long-term average) to produce estimates of total carbohydrate production and how the carbohydrates are then partitioned between the crop canopy and tubers (see flow chart). Apart from producing forecasts of total tuber yield the model can also be used to forecast graded yield. Once data have been collected, crops can be compared and reasons for poor crop performance can be understood.
