PREPARATION OF LAND FOR CORN 



Customary Rate of Planting Corn 



There is a wide range of planting in any region, within which 

 there will be very little effect on yield of grain, although the yield of 

 stover will usually increase with rate of planting. This is due to the 

 adjustment of the plants. With thick planting the ears are smaller, 

 while more plants are barren. The following data show yields at 

 the Nebraska Station for different rates of planting : 



Results with Planting Corn at Various Rates (1903-1908), Nebraska 2 



Where corn is grown for grain there is no good reason for plant- 

 ing thicker than is necessary to secure maximum yield, but where 

 grown for fodder or silage the rate may be increased one-fourth to 

 secure the larger yield of stover. 



Relation of Soil and Climate. The best rate will vary with 

 soils and climate. At the Illinois Station, 3 in a series of experi- 

 ments covering the State, it was found that three kernels gave the 

 best results on land producing more than 50 bushels per acre, and 

 two kernels per hill where the land naturally produced less than 50 

 bushels per acre. 



At the Indiana Station 4 corn was planted in drill rows from 



1908.
