Information in this program is based on data through 2005, applicable to environmental conditions representative of the semiarid northern Great Plains. Mean annual precipitation and temperature at the research site is 17 in (43 cm) and 41ºF (5ºC). Crop sequences were evaluated using no-till production practices. Additional information may be included as data becomes available.
