The small grain performance tests were located at the State Experiment Station, Brookings, the Central Substation, Highmore, the Range Field Station, Cottonwood and the North Central Substation, Eureka.
In most cases the yields at the outlying stations were taken from nursery plots, with the exception of the winter wheat, rye and flax data which came from still strip plots of approximately 1/50th acre in size. The yields at Brookings were taken from drill trip plots 1/40th acre in size.
Since yielding quality cannot be measured with absolute accuracy, small differences in yield are not important. Unless the difference exceeds the “least significant difference” given in the yield tables, little emphasis should be placed on the superiority in yield of one variety over another.
