Analysis method of forage-use potato potential yields

  • The difference between actual and potential yields of crop is called yield gap. Potential yield reflects the theoretical upper-limit of crop production in a certain region. Prediction of crop potential yield can help confirm the upper-limit of crop yield and have an insight into the study and analysis of yield gap and limiting factors of yield. This paper summarized the current progresses in the studies of potato potential yield and proposed the priorities in the study of potato potential yield in the future.

This paper summarized the current progresses in the studies of potato potential yields. The current main problems in the research on the potential yield of potato lies in that the concept, calculation and analysis methods and the analysis mechanism among crop models are different, which result in the analysis results are quite different. In the future, the research on the potential yield of potato should focus on that the growth model of potato is combined with the new techniques of remote sensing technology (RS), geographic information system (GIS), and the study method should change from original single analysis
