is planted in hills with rows running both ways, it is 

 easier to keep the field free from weeds. To have the 

 right number of stalks in the row and an even stand 

 no vacant spaces is very important. It is the safer 

 way, though it requires more work, to plant too thick 

 and then thin to the required number of stalks, leaving 

 the strongest. About ten thousand stalks to the acre 

 is considered the right number in fertile, well-watered 



Spacing soil. This number will be secured if the rows are three 

 and a half feet apart, and the hills three and a half 

 feet apart j with an average of three stalks to the hill. 

 On poorer land two stalks to the hill, or about seven 

 thousand stalks to the acre, will give a better yield. 

 If planted in drills, the stalks should be about fifteen 

 inches apart to give ten thousand to the acre, and 

 twenty inches apart to give seven thousand. 



Depth From two to four inches is a suitable depth at which 



to plant corn. Dry climates require the greater depth 

 (Fig. 84). 



Cultivation Shallow cultivation of corn is best, for the roots are
