14 Portieth Annual Report of the It, therefore, pays to cure corn by kiln-drying and to test the seed for 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 .
