FARM CROPS 



{Continued) 



Having considered the systems and principles 

 concerned with the growth of crops we come to 

 a closer study of the crops themselves. 



Corn Crops. — Each of the corn crops can 

 be sown in either autumn or spring, but the 

 purpose for which they are grown varies with 

 the time they are sown. Wheat sown in 

 autumn is sown to produce grain and straw 

 next summer, but the varieties of oats and 

 barley, termed winter oats and barley, that may 

 be sown in autumn, are only sown as catch 

 crops. Oats and barley when grown for their 

 grain are sown in early spring ; wheat may 

 also be sown in early spring, that is, the variety 

 known as spring wheat, but it is very necessary 

 to make sure that genuine spring wheat is 

 used. If the autumn - sown wheat is doing 

 badly it may be ploughed up and spring wheat 

 put in its place.
