them must finally turn upon the amount of nutriment produced 

 from a given area of land and the cost of production. Woll l 

 presents the following table, showing the green substance and the 

 flry matter yielded by both crops at four Stations: 



Yield and dry matter per acre of roots and green fodder corn Four 



Stations. 



It is seen that fodder corn yields about twice the dry matter 

 that can be secured from a crop of roots grown on the same land. 



394. Dry matter in silage and roots. The value of the dry 

 matter of roots and silage for milk production has been studied 

 at the Ohio, 2 Pennsylvania 3 and Vermont 4 Stations with the fol- 

 lowing results: 



MUk produced by feeding one hundred pounds of dry matter in corn 

 silage and beets Three Stations. 



It will be seen that although practically all of the dry matter 

 of beets is digestible, while a considerable portion of that in corn 

 silage is not, dairy cows, when fed rations consisting largely of
