CORN 



The effect of early and late planting is well illustrated in the fol- 

 lowing tables No. 31 and 32, taken from a report of the Ohio Experi- 

 ment Station. ='= The highest yield of corn was secured with early 

 planting, May 4 to 10. (See Table No. 31.)

A moisture determination made at husking time with a Brown- 

 Duval tester showed the corn from the early planting to be much bet- 

 ter matured. (See Table No. 32.) Throughout the corn belt early 

 planting means an increased yield, and better matured corn. This is 

 not necessarily true however with extremely early planting.

 (Date of planting and per cent of moisture in fall.) 



Depth of Planting. The depth of planting corn is controlled by 

 first, the physic.il properties of the soil and its fertility. A stiff, sticky 

 clay, retentive of moisture and lacking in humus, should be planted
