germination in order to eliminate ears that do not germinate.
VARIETIES.
Many good silage varieties are found in the state. The old Murdock
corn grown extensively in the southern part of the state Is good. Here
and there you find strains of Reed's Yellow Dent, Leaming, Iowa Silver
Mine that have been acclimated. For the northern part of the state
Golden Glow and Wisconsin No. 8 are proving valuable and larger
yielders than the flint varieties formerly grown. Flints give a large
proportion of leaves to stalk but the total production is so small com-
pared with dent varieties that no farmer can afford to use them for
silage. Wisconsin No. 7 or Silver King It the variety which has been
bred by the Station for leafiness. Because of this breeding, this va
riety is outyielding all other varieties In the state In the production
of silage grain. Seed of this can be purchased through seed dealers
In the state or from members of the State Experiment Association
through orders sent to the Station at Madison.
TIME FOR CUTTING CORN FOR SUAGE-Losszs FRom USING Too LATz
MATURNG :VARIEEs.
Experiments show that corn has an exceedingly high percentage of
water during its early growth and even up to the milk stage. During
the glazing stage the percentage of water decreases rapidly and the
dry matter increases to a corresponding rate. In corn producing 13
tons green material per acre there Is approximately two tons more
dry matter than when in milk. If cut at the milk stage this amount of
dry matter is therefore lost. The time to cut corn for silage to get
the largest amount of food material is therefore at the glazing or ripe
stage. Where southern corn is used It must of necessity be cut before
It is sufficiently mature and the farmer therefore suffers the above
mentioned loss. Jordan of New York found that only 65% of silage
from southern corn was digestible as against 73% of northern corn.
During the early stages of the growth of corn a large part of the
material which later becomes starch Is in the form of sugar. When
the green corn is placed In the silo, fermentation and chemical changes
take place in this sugar as a result of which it is changed to alcohol,
acid and carbon dioxide. The result is a large loss of the sugar so
far as feed value is concerned, and further, the production of sour,
unpalatable, bad smelling, unhealthful silage. Results of such work
can be noticed in passing silos along the road where the bad odor can
