SPRING CEREALS AT MORO, OREG. 37 
Seventy-six varieties of spring wheat have been tested for two 
or more years. Early Baart wheat (C. I. No. 1697) produced 
the highest average yield, 22.2 bushels 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 in 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.
