摘要：
Site-specific yield measurement and monitoring are fundamental elements of the use of precision agriculture in sugar beet. The technical approach is the measurement-of the mass-flow of clean beet without technical related losses. The system is designed fore clean, not harvested beet. There are two principles of measurement, the first one is an online system for counting beets. By multiplication with the average single beet mass it is possible to calculate the site specific yield. The second principle is build up on the previous system. Instead of using an average beet mass, the diameter in working. direction, which correlates highly with real beet mass (R-2=0,94), has to be measured to determinate the yield. The beet can be detected by overlaying two profiles which an be build by measuring and connecting the vertical distance. with laser-, paddle- and ultrasonic, sensors and the way. with radar or a peiseler-wheel. In field trials both systems works successfully under optimised condition.
