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 Bluesteni, 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 Talinika, 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.
