ACIDITY OF SUNFLOWER SILAGE 
Table IV shows that there is more acidity formed when sunflowers 
are siloed in the later stages of growth than when siloed in the earlier 
stage. This fact is different in com silage, since immature com always 
produces more acidity than com siloed at a mature stage. The total 
amounts of acidity, however, found in these samples of sunflower silage 
easily fall within the amounts usually found in good sunflower silage. 
It must be remembered that kind of acids present is more of a criterion 
of good silage than quantity of acids. All silage samples made at the 
different stages of growth were classed as good samples when acidity, 
odor, and color were used as the criterion. The earlier stages would 
not be as suitable for silage purposes as the later stages, due to the large 
percentage of moisture which they contained. Even the last stage cut 
contained slightly higher than 80 per cent of moisture, but it must be 
remembered that these samples were not allowed to be exposed to the
