Muscatine Island Farm
Sugar beets were grown for the first time at the research farm in 2008 in a project exploring potential biofuel crops. The sugar beets grew fairly well but during the growing season nutrient deficiency symptoms were noted and at harvest yields were not as high as expected. The symptoms observed were similar to those reported for boron deficiency in sugar beet. The foliage became chlorotic (yellow) and the crown region developed dark necrotic areas resulting in cavities and abnormal crown growth. Thus, this study was initiated to investigate a possible boron deficiency by applying boron fertilizer treatments and observing effects on leaf nutrient levels and root yield of sugar beet grown on a Fruitfield soil.
