Investigations of 1916 
In the work of 1916 the crops used for silage were corn, oats (A vena sa¬ 
liva), and peas (Pisum spp.), and wheat (Triticum aestivum) and peas. 
These crops were siloed in the three large concrete silos located on the 
University farm. Particular attention was given to the factors con¬ 
cerned in developing good silage—namely, fineness of cutting, thorough¬ 
ness of packing, and the proper moisture content.
