Factors affecting recent trends in sugar beet yields and implications for sugarcane productivity* [Full subscriber]

Abstract         Yields of sugar beet have risen steadily for almost the last four decades, whereas yields of sugarcane have not.  This study uses the literature to examine some of the reasons for this difference.  Beet has benefitted from climate change (warmer springs and autumns and increased CO2 concentration in the atmosphere) to a much greater extent than cane.  Because beet is raised from seed that is always produced under the direct control of the plant breeder, improvements in cultivars are taken up very rapidly, whereas the ratoon production of cane means that improvements are inevitably transferred to commercial practice more…
