SPRING CEREALS AT MORO, OREG. 



31 



but two or three days earlier than most other varieties. The straw 

 is tail and coarse, and the heads are very large and open (fig. 15). 

 The kernels are white, short, and broad. The two prominent char- 

 acteristics of this variety are the wide-spreading heads and the short 

 kernels. One of its principal faults is a tendency to produce only 

 one grain to the spikelet, the second or smaller grain often being 

 entirely inclosed in the hull of the first. That this tendency has not 

 been marked at the Moro substation is shown by the weight per 

 bushel, which is higher than that of any other variety. 



SPRING BARLEY. 



Next to wheat, barley is the most important cereal grown on the 

 dry lands of the Columbia Basin. Most of the barley grown is sown 

 in the spring, though at the lower elevations winter barley is grown 

 successfully. 



VARIETAL EXPERIMENTS. 



At the substation 43 varieties of spring barley have been tried. 

 Acre yields have been obtained from 13 of these in each of the five 

 years, 1911 to 1915, inclusive. Owing to an exceedingly unfavorable 

 season the barley yields were low in 1911. In 1912 the spring-barley 

 varieties were placed on poor soil and no high yields were obtained. 

 In 1913, 19i4, and 1915 the yields of most of the varieties were con- 

 siderably higher than in previous years, and spring barley exceeded 

 any other spring crop in total weight of grain produced per acre. 



In Table XVII will be found an alphabetical list of the spring- 

 barley varieties grown two or more years, with the yields of each 

 variety in bushels per acre. These yields are based on the yields 

 of single tenth-acre plats in 1911, 1912, and 1913 and of duplicate 

 twentieth-acre plats in 1914 and 1915, except as otherwise stated.

 sizes at the Moro substation within the 5-year period, 1911 to 1915, inclusive, showing 

 also the source of seed and group relationships.
