SPRING CEREALS AT M0R0, OREO. 37 



Seventy-six varieties of spring wheat have been tested for two 

 or more years. Early Baart wheat (C. I. No. 1607) produced 

 the highest average yield, 22.2 hushels per acre, in the five years, 

 1911 to 1915, inclusive. The selection from Koola (C. I. No. 

 2203-2) gave the highest three-year average yield, 27.7 bushels per 

 acre, in the years 1913, 1914, and 1915. 



The average yield of 14 varieties of common and club wheat 

 •varieties in 1913, 1914, and 1915 exceeded the average yield of two 

 durum varieties by 3.5 bushels per acre. The average yield of the 

 highest yielding common wheat exceeded the average yield of the 

 highest yielding durum wheat by 7.7 bushels per acre in the same 

 period. 



Milling and baking tests of several of the spring-wheat varieties 

 grown at the Moro substation have been made by the Plant Chemi- 

 cal Laboratory of the Bureau of Chemistry of the United States 

 Department of Agriculture. These tests indicate that most of the 

 varieties are as good as and some are better milling wheats than the 

 Pacific Bluestem, which is the standard spring wheat of the Colum- 

 bia Basin. 



Date-of-seeding experiments with Pacific Bluestem spring wheat 

 indicate that seeding as early hi the spring as possible gives the best 

 'results. 



Rate-of-seeding experiments with the Pacific Bluestem variety 

 indicate that for early spring seeding about 5 pecks per acre is the 

 best rate. For late seeding 3 pecks per acre produced the highest 

 yields. 



Of the oat varieties under experiment, the early varieties, like 

 Kherson and Sixty-Day, have given the best results, though Siberian, 

 a variety maturing in midseason, has given yields practically as high 

 as the Sixty-Day and Kherson in a 5-year average. 



Forty-two varieties of spring barley have been tested, and 5-year 

 average yields obtained for 13 varieties. The variety giving the 

 highest average yield in the five years was Mariout, C. I. No. 261, a 

 6-rowed form, yielding 34.3 bushels per acre. The 2-rowed forms 

 White Smyrna and Hannchen produced average yields in the same 

 period of 33 and 32.2 bushels per acre, respectively. 



Spring emmer has not given as good results as spring barley or oats. 



The grain sorghums have not produced profitable returns. Of the 

 varieties tested, Manchu kaoliang is the most promising. 



The 5-year average acre yield in pounds of the highest yielding 

 varieties of the three leading cereals was as follows: Wheat, 1,362 

 pounds; oats, 1,402 pounds; barley, 1,646 pounds. 



Based on the 10-year average farm price of these cereals in Oregon, 

 the acre value of wheat would be $18.39; oats, $19.35; and barley, 

 $20.35.
