Development of a Measurement Device for Root Diameter of Sugar Beets

Abstract

A nondestructive and continuous measurement device for sugar beet root was developed. This device can be installed between sugar beet stocks and operates for a long time without any external power supply. Since the device is able to measure the horizontal dilation of the sugar beet in the soil by being placed vertically on the ground, it could be applied in an actual field. Experimental results showed a small margin of error which indicates the possibility of practical applications. The ability of the device to monitor roots during growth provides information which may improve the prediction of the harvesting time, hence, the yield and reduce the costs spent on growth investigation.
