During five years the average yield of dry matter has been 

 for the dent variety 5,036 pounds and for the flint variety 4,224 

 pounds. The Pennsylvania Station^ found that the dent fodder 

 yielded forty-five per cent more dry matter than flint fodder. 

 The flint variety contained a considerably larger percentage of 

 protein and smaller percentage of crude fiber. At Cornell 

 Station ^ Sibley's Pride of the North yielded ten per cent more 

 dry matter than an eight-rowed flint. Ontario Agricultural 

 College compared the feeding value of dent maize and sweet 

 maize silage and found the latter slightly superior in feeding 

 value — ^believed to be due to greater palatability in this case — 

 but the increased yield of dent maize more than compensated 

 for the decrease in feeding value.* 



Varieties originating in the South Atlantic and South Central 

 States are frequently sold in the North Atlantic and North 

 Central States as silage maize. The season of growth being 

 longer than northern grown varieties, they continue to grow later 

 in the season, thus often producing a greater yield of silage per 

 acre than those varieties grown principally for their grain. 

 These so-called silage varieties do not produce as large a propor- 

 tion of ears to stalk and leaves, and in many cases the per cent 

 of water is higher, thus requiring the handling and storing of more 

 tons of silage for an equal amount of dry matter and of food 

 value. When silage is put up too green its keeping quality and
