82 MISSOURI AGRICULTURAL REPORT. 



Mr. Don't you think that farmers should stud}- to know 



their type of soil in studying the type of corn to plant? 



Dr. Tucker — Within certain limits. Of course there are different 

 types of soil and corn becomes adapted to a certain type, and should 

 not be changed abruptly to a different type of soil. The Boone County 

 White is adapted to a fertile soil and when put on a clay hill, it probably 

 would not produce as well as some other variety. 



THE QUERY BOX. 



(Conducted by I'lof. F. B. Mumford.) 



Q. Will it do to cultivate corn after it gets too large for the two- 

 horse cultivator? 



Mr. Laughlin — Yes sir, for the reason that the corn does not really 

 begin to make its growth until brace-roots are formed. The object 

 of cultivation largely is to get rid of the weeds and other grasses that 

 grow around them and which would take up the nutrition that the corn 

 plants should have. 



Prof. Mumford — What kind of cultivation ought we to give? 



Mr. Erwin — Just as shallow as it is possible and disturb as few of 

 the roots as possible. 



Prof. Mumford — What is shallow cultivation and what is deep 

 cultivation ? 



Prof. Miller — Usually shallow cultivation runs about 2 1-2 inches 

 on upland. On some soils., it might be considered that 3 or 3 1-2 inches 

 would be shallow. It depends upon the soil largely, but 2 to 2 1-2 inches 

 would be pretty shallow cultivation. With very wide shoveled culti- 

 vators that would be out of the question, but with fine toothed instru- 

 ments, it should be about 21-2 inches. 



Q. Will white corn yield more per acre than yellow corn? 



Prof. Mumford — The yield of corn does not depend upon color. 



Q. Is there any virtue in the cob? If not, what is gained by 

 grinding it? 



Prof. Forbes — Grinding the cob with the meal is of benefit only 

 in feeding steers. It is of no benefit in the feeding of hogs. We 

 grind the cob with the meal, not because of any very great amount of 

 nutriment that it contains, but in order to lighten up the meal. If fed 

 to a hog, it is a detriment to the animal. For steer feeding, if corn is 

 worth 30 cents per bushel, we are adding 7 1-2 cents worth to it by 

 grinding and if we can grind for 71-2 cents a bushel, it is worth it, but 

 if not, it is not.
