Yields have been the main records kept from the Old Rotation since 1896. A complete record of all yields from the first 100 years were published by Mitchell et al. (1996). These were summarized by Mitchell et al. (2008). Until 2003, all yields were non-irrigated. Since 2003, separate records were kept of irrigated and non-irrigated yields. Recent yields are presented in the tables and figures.
