✦ Synopsis
Sugar content and beet yield data from variety trials as well as sugar content data from commerical farms were analysed to obtain weather-based models which could explain variations of tuber and sugar yield and be used for forecasting purposes. Both sugarbeet yield parameters were found to be related to the sums of thermal deviations from the optimum ranges. Quantitative relationships have been established and the precision of prediction and function of prediction time have been examined and presented. It is shown that most sugarbeet growing areas of Iran are too hot during August and September. Using commercial data, quantitative relationships were established such that using August and September temperatures, the thermal suitability of an area for maximum sugar content could be determined.
