CEKEAL INVESTIGATIONS AT THE NEPHI SUBSTATION. 27 



high percentage of winter survival among the plants. Then Mr. 

 Boswell planted all the seed he had obtained from the second year's 

 crop on his dry farm, which adjoins the substation on the south. 

 He succeeded in getting a yield of 50 bushels to the acre in 1908 

 and since then he has obtained yields of from 25 to 40 bushels to the 

 acre each year. 



The yields obtained on the substation have not been so large as 

 those on the Boswell farm. In 1907 the crop was planted on land 

 that had produced a crop of wheat that year, and so much volunteer 

 wheat grew that it was impossible to determine the oat yield in 190S. 

 In 1909 the yield was 16 bushels per acre and in 1910 only 5.3 bushels. 

 This low yield is difficult to understand, for on the Boswell farm and 

 on some other farms in that vicinity where the oat was planted 

 at approximately the same time a yield of about 25 bushels per acre 

 was obtained. From the general appearance of the plat it was 

 thought at the time that the drill had " missed" considerably at 

 seeding time. This, however, was not known to have been the case. 

 In 1911 a yield of 38.1 bushels per acre was obtained at the sub- 

 station, while about 35 bushels per acre were obtained on the Boswell 

 farm. The average yield at the substation during the period from 

 1909 to 1912 was 17.2 bushels per acre. 



In the fall of 1911 a rate-of-seeding test and a date-of -seeding test 

 with the Boswell Whiter oat were begun. The highest yield obtained 

 from these tests in 1912 was 19.8 bushels per acre; the lowest yield 

 was 0.5 of a bushel. The average yield of eight plats in the tests 

 was 9.2 bushels per acre. One other plat yielded 15 bushels per acre. 



Although the Boswell Winter oat has not given very satisfactory 

 yields on the substation, it is a promising variety. The rate, date, 

 and depth of planting largely govern the yield, and these factors are 

 being determined. 



This variety has been sown extensively on farms in various parts 

 of the West, and reports show varying degrees of success. In many 

 localities it is believed that this oat will prove a success, while in 

 other localities the results are not so promising. The color of the 

 hull is objected to commercially, but the quality of the oat is very 

 high and it is a valuable stock feed. 



Spring Oats. 



Seven varieties of spring oats have been tested. Three of these — 

 the Sixty-Day, the Black American, and the Giant Yellow — have 

 been grown since 1904. The Swedish Select and an improved strain 

 of Sixty-Day were obtained from the Highmore substation in South 

 Dakota hi 1908. The former has been grown since that time, 

 but the latter was discarded in 1909 because it was mixed with 

 another variety. The Kherson variety was received from the Akron
