The Fruit Experiment Station (OVA) was founded on 1 April 1935 as an offspring of the regional Advisory Service. Due to apple scab and apple sucker, profitable fruit production was all but impossible at the time. Therefore, crop protection strategies had to be devised during the 1930s. Recurrent frost damage in the 1940s led to the initiation of a regional breeding programme which produced successes such as the apple variety ‘Gloster’, the sweet cherry variety ‘Regina’, and rootstock J9. After the 1962 storm tide, the experimental farm moved to the Esteburg site during the 1960s. Economic pressure during the following two decades demanded productivity gains and more widely marketable fruit varieties. This led to a switch in production from seedling rootstocks to rootstock M9 during the 1970s and 1980s, and to the introduction of the two lead varieties ‘Elstar’ and ‘Jonagold/Jonagored’ which have remained the most important varieties to this day. Further trends with an influence on current fruit production are the development of the concept of Integrated Production at the end of the 1980s, negotiations towards a special regulatory status of the region, and the beginning of experimental work for organic fruit production. Following the accommodation of the class of vocational education, a holistic concept of research, advisory service and education at the ESTEBURG site represents the foundation for a successful future.
