THE CHEMICAL DEVELOPMENT OF ALFALFA. 163 
blossoms appear in order to secure, in the cured fodder, the 
largest percentage of protein, and the smallest percentage 
of fiber. By cutting as early as possible the growth is 
stimulated and more time is given for the second and third 
crops to reach maturity. Table LXVII gives the number of 
grams (28.3 grams in one ounce) of nutrients yielded by one 
square vard at the different stages.

On June 30th, a square yard sample was taken of the 
second crop when it was about six inches high, and four 
samples were taken thereafter at weekly intervals, the last 
sample being taken July 29th, five days after the crop was 
harvested. The first blossoms appeared about July 22nd. 
These five samples were taken from the field of Turkestan 
alfalfa mentioned on page 162 and were prepared for an- 
alysis in the same way as those from the first crop. Table 
LXVIII gives the results of the analyses of these five samples.
