A Study ot Colorado Whlat 107 
Owing to the prevalence of mealiness in the kernels, mentioned 
in the last paragraph before the table, we would expect a rather low 
percentage of crude protein, but, according to our previous observations, 
we would not expect any noticeable increase in the starch. We have 
given, among our general samples, three of this variety grown at Fort 
Collins on fallowed ground, and with one irrigation. These are higher 
in protein but quite similar, in regard to the starch, to the Idaho sam¬ 
ples. The protein in our samples is 13.8, 14.0, and 16.0, while the 
starch is 59.1, 60.2, and 59.9 percent. Our samples received but one 
irrigation, about 12 June, which was probably at the rate of i foot to 
the acre, or perhaps less. The Idaho samples received from three to 
seven applications of water, aggregating from i to 3 feet. At the 
present we will.consider the Idaho samples by themselves. The appli¬ 
cations of 2 and 3 feet of water increased both the yield of straw and 
wheat, and the manure effected a further increase. The unmanured 
plots yielded 1,000, 1,144 1,266 pounds of wheat per acre with i, 
2 and 3 feet of water; the manured plots yielded 1.467, 1.663 1.826 
pounds with the respective applications of water. The effects upon the 
amounts of straw were relatively the sanTe. From the standpoint of 
dry matter produced, it is evident that there is an increase due to the 
more liberal application of water. The manure produced an increase 
in crop and the application of larger quantities of water produced its 
own effect, which was slightly enhanced by the influonce of the manure. 
This phase of the question is mentioned merely for the purpose of 
• taking cognizance of the facts in the case and not for the purpose of 
discussing them. The feature that I want to present is: What, if any, 
was the effect of the different quantities of water applied upon the 
composition of the grain? The preceding statements will be deemed 
as sufficient so far as the crop is concerned. 
Experiments of 1914 Give Practically the Same Results as In 1913 
These analyses, when compared with one another, dO' not show 
any differences in composition which can be attributed to either the 
water or the manure. By common consent, justified by the facts, we 
look to the nitrogen content as the key to the solution, but we may in this 
case take all of the constituents one by one, and we will arrive at the 
same conclusion, i.e., that there is no variation due to these factors of 
sufficient size tO' justify serious consideration. It is true that there is 
a shadow of difference in the amount of protein present in favor of ,the 
produce from the manured plots reaching 1.4 percent in the case of the 
manured plot that received 3 feet of water. That 15-67 loads, probably 
not far from 16 tons, of well-rotted manure per acre should have so 
little, practically no effect upon the composition of the grain, is a 
little surprising at first sight. The water was applied, as has been 
stated, at different intervals up to within ten days of* full maturity.
