Rates of Production of Crops and Animals 



In spite of a large farm business, the operator's ultimate profits must 

 be seriously impaired if rates of production of crops and animals are 

 low. In fact, it is entirely possible for crop jnelds and animal produc- 

 tion to be so poor that profits will decrease witli increasing size. 



Crop Index 



Bushels and tons are hard to compare in respect to production. To 

 alleviate this difficulty, a single figure for indicating crop yields has 

 been developed which expresses the average yields of all crops on a 

 given farm in terms of some group or regional average. This is called 

 the crop index. (See definitions.) For practically the same reasons 

 that crop acres failed to measure size in the area studied, crop index 

 falls short of measuring quality in a highly significant way. Since 85 

 per cent of the crop land on the farms surveyed Avas found in grass and 

 clover and a very small volume of intensive cash crops was grown, 

 crop index is largely a reflection of hay yields regardless of its weight- 

 ing by work units. 



The best yields of timothy hay, which once commanded a good mar- 

 ket price, have never provided a highly desirable feed for dairy cows. 

 Smaller yields, mixed grasses and larger areas may actually satisfy the 

 roughage requirements on a dairy farm quite as accei)tably. New
