FARM ARITHMETIC PROBLEMS 105 

 Corn. 



The usual distance between hills is 3 ft. 8 in. If 

 checked at this distance apart, there are 3240 hills 

 in one acre. If there is a perfect stand, three stalks 

 in a hill, and each stalk has one twelve- ounce ear of

 on an acre. Yet, the average yield in the United 

 States is only 38 bu. to the acre. 



To secure a good yield of corn we must have 

 good seed, good soil and good cultivation. 



Corn Judging. 



The object in judging corn is to determine the 

 corn that when planted will produce the most corn 

 of the best quality. The score card used by the 

 Extension Department of the Iowa State College of 

 Agriculture is plain, logical and easily grasped. It 

 takes up the points under four heads. 



I. WILL IT YIELD ? 25 points. 



That is, will it yield well; has it constitu- 

 tion; can we depend upon it even when weather 

 conditions are unfavorable? 



II. WILL IT RIPEX? 25 points. 



That is, will it mature; will it ripen every 

 year; is it safe for the locality? 



III. DOES IT SHOW IMPROVEMENT ? 25 

 points. 



That is, has it breeding; has it a distinct
