THIRD ANNUAL SESSIONS 



Protein Experiments. 



"Beginning with the Crimean wheat, we notice that the per cent 

 of protein in the original Kansas seed, grown in 1905, was 14.53 ;in 1906, 

 the following is the composition: Kansas, 17.27; California, 9.8, and 

 Texas, 10.88; a difference of over 8 per cent, due entirely to a change 

 of environment. In 1907 all three plots of wheat grown in Kansas from 

 Kansas '06 seed, Californi'a '06 seed and Texas '06 seed, gave the follow- 

 ing: 20.23 per cent, 20.73 per cent and 20.45 per cent respectively Those 

 grown in Texas in 1907 from Texas '06 seed, Kansas '06 seed and Calif- 

 ornia '06 seed, gave 16.45 per cent , 15.33 per cent and 16.47 per cent, re- 

 spectively And those grown in California in 1907 from California '06 

 seed, gave 10.26 per cent, 10.26 per cent and 9.91 per cent, respectively. 



Kansas Results. 



"It will thus be seen that apparently the crop is not at all influ- 

 enced by the composition of the seed nor by the source of the same. 

 For example, California seed of 1906 with 9.8 per cent protein, increased 

 to 20.74 per cent in Kansas in 1907, or 120 per cent, whereas Texas seed 

 of 10.88 per cent protein gave 20.46 per cent in Kansas, and Kansas 

 seed with 17.27 per cent protein gave 20.23 per cent when again grown in 

 Kansas. In other words, all the grain grown in these three plots in Kansas, 

 viz., from California seed, from Texas seed, and from Kansas seed, all 

 three differing in protein content from 9.8 per cent to 17.27 per cent re- 

 spectively, produced a crop of identical protein content, and of prac- 

 tically the same composition generally, the weight per 1000 kernels, 

 the weight per bushel, and character of the grain being same. 



California Results. 



"In the same way, when the Kansas seed with 17.27 per cent, pro- 

 tein, the Texas seed with 10.88 per cent, protein, and the California seed 

 with 9.8 per cent, protein, were all grown in California, the composition 

 of the resulting grain from the three plots was almost identical, viz.: 

 9.91 per cent, 10.26 per cent, and 10.26 per cent, protein. The per cent, 

 of the other constituents was likewise the same in all three samples, as 

 were also the physical characteristics. 



Texas Results. 



"The three samples grown in Texas from Kansas seed, California 

 seed, and from Texas seed, likewise were identical in composition and 

 in physical appearance, although the seed producing them var- 

 ied widely, as we have just seen, both physically and chemically. 

 The same kind of results were obtained with Kubanka wheat grown in 

 South Dakota, Kansas, and California. 

 Dry Land Gave Higher Percentage. 



"The figures just quoted give the protein contents calculated on a 

 wet basis, the samples containing about 10 per cent, of water. Calculated 

 on a dry basis, the protein content is about 2 per cent, higher in each 

 case.
