No one of the varieties of corn yielded largely, and under the 

 existing conditions this was not to be expected. In fact the 

 experiment was planned with reference to a comparison of yield 

 and not to secure a maximum crop. 



The growth of dry matter, as well as of green fodder seems to 

 have been much larger with the southern ensilage corn. Would 

 this have been true under more favorable conditions? A future 

 experiment must more definitely answer this question. 



One fact is plainly seen, however, which is, that 36,475 pounds 

 of green fodder contained only 5,073 pounds of dry matter, and 

 31,402 pounds of water, or in other words, over eighteen tons of 

 green material grown on two acres, furnished only two and one- 

 half tons of dry substance. This is less dry matter per acre than 

 is furnished by the average grass crop on very many of our well 

 tilled Maine hay farms, and in the case of the hay fifteen tons of 

 water are not present to be lifted several times. There would be 

 no reason for mentioning the poor economy of this crop were it 

 not for the fact that many such crops of corn fodder have been 

 grown and may still be grown in Maine on land of moderate 

 fertility, and from late planted seed. More liberal manuring and 

 greater maturity are essential conditions of success in the growth 

 of the corn plant for the silo. 



But the amount of dry matter is not the only factor involved in 

 the consideration of nutritive value. The southern corn was 

 harvested, as must always be the case in Maine, in a much more 

 immature condition than the other two varieties. This fact must
