Spring wheat. Spring wheat is adapted to localities 

 where climatic conditions are not favorable to winter vari- 

 eties. About one-third of our wheat comes from the spring- 

 sowed crop. Most varieties of spring wheat require from 

 one hundred to one hundred and twenty-five days from the 

 date of planting to mature them. 



Minnesota, North Dakota and South Dakota are the 

 principal spring wheat regions of the country. These three 

 states supply seventy per cent, of all the spring wheat 

 grown in the United States. 



TOPICS FOR INVESTIGATION 



1. What proportion of the tilled land of your vicinity 

 is devoted to wheat? Is this proportion increasing or de- 

 creasing ? 



2. What type of wheat is chiefly grown, winter or 

 spring? Hard or soft? Do you know what are the chief 

 varieties to be found in your neighborhood? Are the vari- 

 eties bearded or beardless ? 



3. What is the average yield of wheat to the acre in 

 your region ? How does this compare with the yield for the 

 state? (Consult your state agricultural college for the 

 yield of the state.) 



4. It is estimated by the United States Department of 

 Agriculture that the average cost of producing an acre of 

 wheat in the United States is about eleven dollars, includ- 

 ing rental or interest value of land. Talk with your father 

 about what the different items of expense cost in your 

 vicinity (such as fertilizer, preparing land, seed, planting, 

 harvesting, thrashing, marketing, rental). Make a detailed 

 list of these expenses, and compare with the average cost for 

 the country. 



5. In a similar manner figure what it costs to raise an 

 acre of corn. Then find the market value of the grain
