The yield gap in some sugar beet producing countries † [Full subscriber]

The efficiency of an arable crop production system can be expressed as the yield gap, the difference between the potential yield and the actual yield. The larger the gap, the less efficient the system. One way to assess the yield gap for sugar beet production is to compare the delivered yield with the yield produced without any farmer-imposed constraint, where the yield of the crop is limited only by the availability of heat, sunlight and water. Official trials designed to produce lists of recommended varieties usually suffer few, if any, constraints. The Plant and Soil Group have collected national yield…
