CEREAL INVESTIGATIONS AT THE NEPHI SUBSTATION.

also, that all of the leading varieties are of the hard winter group and 

 most of them were introduced at the station since 1907. 



After ranking the varieties in the manner described most of those 

 ranking below the thirtieth position were discarded from the plat 

 tests. The others were sown in the fall of 1911. A few varieties 

 which are popular with the farmers in the Mountain States were con- 

 tinued in the plat test despite their low rank. 



Results in 1912. — The fall of 1911 was very dry, and seeding was 

 delayed considerably. After it had been finally accomplished 

 extremely cold weather set in and it is believed that there was a 

 great deal of fall killing. The winter, too, was dry and cold. As a 

 result of this weather a very poor stand was obtained on the plats 

 of winter grains, and the yields were low in comparison with those 

 of 1911. The highest yield per acre in 1912 was 22.8 bushels for 

 Bulgarian (C. I. No. 2048), and the lowest yield per acre was 5.8 

 bushels for Ulta (C. I. No. 1439). 



Summary of winter wheat yields. — The rank of the best yielding 

 winter wheat varieties grown at Nephi from 1908 to 1912, inclusive, 

 is shown in Table IX, where they are ranked according to their 

 average actual yields. The check plats of 1912 were so badly winter- 

 killed that their yields are not dependable for use in figuring the 

 computed yields of the other varieties, so no 5-year rank on com- 

 puted yields is available. 



Table IX. — Annual and average yields of 28 varieties of wheat grown at the Nephi sub- 

 station for five years, 1908 to 1912, ranked according to their average actual yields.
