494 FARM AND SCHOOL PROBLEMS. 



The experiment shows that for every five bushels' increase 

 in the corn crop there was an increase of one ton of silage. 



PROBLEMS. 



1. How many tons of silage can be made from a field of ten acres 

 that will yield an average of 45 bushels per acre? 



2. How many acres of corn yielding 50 bushels per acre will be re- 

 quired to fill a silo 11 feet in diameter, and 32 feet high? 



3. A farmer wishes to construct a silo that will hold the required 

 amount of silage to feed 30 cows 180 days ; what will be the dimensions of 

 the silo, and how many acres of corn producing 60 bushels per acre, will be 

 required to fill it? 



4. A silo 36 feet high and 12 feet in diameter is filled with corn 

 silage; 10 cows were fed on an average 38 pounds of silage per cow each 

 day for 180 days; how many cows each consuming 40 pounds of silage 

 per day, will be required to eat the remainder of the silage in 60 days? 



It has been estimated that on an average, about 65 per cent 

 of the food value of the corn crop is in the ears, and about 35 

 per cent remains in the fodder, when used together as silage. 



It has also been determined that two and one-half tons of 

 silage are equivalent to one ton of timothy hay in feeding value. 



PROBLEMS. 



1. If a field that produces 50 bushels of corn per acre will yield 10 

 tons of ensilage per acre, what would be the amount of timothy hay 

 that would be equivalent in value to one acre of this corn as ensilage? 



2. If corn is worth 50c a bushel, and corn stover is worth $3 per 

 acre, what is the value of a corn crop of 10 acres, yielding 75 bushels 

 per acre? What would be its value as silage when timothy is worth $9 

 per ton? Find the difference in the value of the corn plus the stover 

 and the value of the silage 



3. ,Find the capacity of a silo 10 feet in diameter, 30 feet high, and
