A Study ot Colorado Wheat 
105 
3 acre-feet of water, 3,489 pounds of straw and 1,826 pounds of grain. 
The unmanured plots yielded as follows: One foot of water, 1,713 
pounds o^ straw and 1,000 pounds of wheat; 2 feet of water, 2,183 
pounds of straw and 1,144 pounds of wheat; 3 feet of water, 2,511 
founds of straw and 1,266 pounds of wheat. The distribution of the 
water was as follows: Those plots that received i foot of water were ir¬ 
rigated 2 June, 19 June, and 16 July, those that received 2 feet of water 
were irrigated 21 May, ii June, 26 June, 8 July and 15 July; those that 
received 3 feet of water were irrigated ii, 20 and 29 May, 12 and 25 
June, 3 and 15 July. The grain was ripe by the 24th or 25th of July, 
or 114 days from planting- The plots were harvested as soon as ripe 
and the grain threshed ii August. The variety used this season was 
the Marquis. The grain without exception was good. The individ¬ 
ual kernels were of good size and well filled, 1,000 kernels from the 
unmanured plot that received 2 feet of water weighed 33.90 grams, 
and from the corresponding manured plot 35.77 grams. I judge the 
latter to be the very best of the six samples. All of the samples con¬ 
tain many half-mealy or mealy berries. No distinction can be made 
in this respect between the grain grown with or without manure, with¬ 
out a very careful count which, owing to the color of the berries, would 
be very difficult to make with any high degree of accuracy. If any dis¬ 
tinction can be made between the samples in this respect, the second 
sample given above may be the least affected of the six. This was 
grown on a manured plot with 2 feet of water- The analyses of these 
samples including the ash constituents follow:
