Yes, there is an alternative to wheat-fallow in this area. Research at the three western Kansas branch stations (Colby, Garden City and Tribune) report data supporting such a statement, though by no means are the results the same. The wheat-sorghum-fallow system was developed for Kansas by the Fort Hays branch station (22 to 24" annual precipitation) for the central part of the state. The map of normal annual precipitation in Kansas for the period 1951-1980 shows that Colby and Garden City have between 18 and 20 inches, whereas Tribune has less than 16 inches. Work was started at the western branch stations in the early 1970's to study the application of the WSF system to this drier region. A brief summary of data is presented below and more complete data are available from each of the branch stations. ·
