i Discarded after 1907. 



In Table VII is shown a wide variation in the yields of the varieties 

 at the different places. The Nephi wheats yielded less in 1908 than 

 they did in 1907. The Kansas wheats yielded much more at Nephi 

 in 1908 than they did at McPherson in either 1907 or 1908, while 

 the California wheats yielded much less than they did at Modesto 

 in 1908, though more than in 1907. Some of the varieties which 

 yielded well in Kansas in 1907 yielded much less at Nephi in 1908, 

 and in other cases the reverse was true. It is interesting to note 

 that the average yield of the Kansas wheats grown at Nephi in 1908 

 was approximately the same as that of the Nephi wheats. 



Results in 1909. — In addition to those varieties which were grown 

 at Nephi in 1908, three new varieties were sown in the fall of that 

 year. These were Rieti (C. I. No. 2942, S. P. I. No. 17994), from 

 Italy; Turkey, from near Salina, Kans.; and Turkey, from Montana. 

 In addition to these, the two following varieties, which had been 

 grown in 1907 but not in 1908, were sown, namely, Odessa (C. I. No. 

 3274), a soft, amber-grained, brown-chaffed variety; and Lofthouse 

 (C. I. No. 3275), a soft, white-grained, white-chaffed variety. Thus 

 the 1909 varietal test included 63 varieties, grown in tenth-acre 

 plats. 



The yields in 1909 were generally much lower than those of 1908. 

 It is believed that this was due to winterkilling, which will be dis- 

 cussed later. The stand on many of the plats was thin, and as a
