CHAPTER VII 

 FACTORS IN WHEAT PRODUCTION 



THERE are three important factors to be con- 

 sidered in the actual production of wheat : the 

 land, located where soil and climatic conditions 

 are favorable ; the machinery for tillage and 

 harvesting ; and the power for driving the ma- 

 chinery. Since these factors vary greatly in the 

 different wheat-growing regions, the production, 

 both in the items of cost and quantity, is directly 

 concerned with each of them. 



Wheat-producing Areas. - The principal wheat- 

 producing countries are in the temperate zones. 

 They lie between parallels 30 and 60 north and 

 27 and 40 south latitudes. The exceptions to 

 this are the three plateau-like areas including 

 parts of India, Egypt, and Mexico. In these 

 plateaus the higher altitude offsets the effect of 

 tropical location. 



The Effect of Climate on Wheat Production. - 

 Though wheat may be grown in warm latitudes, 

 it is of commercial importance only in countries 

 which have warm summers and moderately cold
