a Acre yields are based on yields from single tenth-acre or duplicate twentieth-acre plats unless other- 
wise stated. 
6 Grown in 2-rod rows replicated 2 to 4 times. d Grown in rod rows, usually unreplicated. 
c Grown in single fortieth-acre plats. « Grown in head rows, yield not recorded. 
As the leading variety of spring wheat in the Columbia Basin is the 
Pacific Bluestem, this variety has always been grown on check 
plats. Table X presents a list of the spring-wheat varieties that 
have been grown three or more years, with yields expressed in per- 
centages of the yield of the Bluestem variety. Where the varieties 
have been tested on areas smaller than one-twentieth of an acre, the 
average yield of the two highest yielding check plats or rows of the 
Pacific Bluestem was used as a basis of comparison. Where the 
test was on areas of one-twentieth acre or larger, the average yield of 
all Bluestem check plats was used. In all cases where the smaller 
areas were used, the Bluestem variety was sown in every fifth plat or 
row. It will be noted that certain varieties, like Koola, Karun, 
Early Baart, and Talimka, have given consistently higher yields 
than the Pacific Bluestem when grown in rows and in plats. 
Table X. — Yields of spring-wheat varieties grown at the Moro substation during three 
or more years, expressed in percentages of the average yield of the Pacific Bluestem 
variety grown in check plats and check rows.
