The reason for this rule is that, under the first set of conditions, the 

 young plants would tiller or multiply and thus make a good "stand,"'' 

 while under the second set of conditions little tillering would occui'. 

 Experiments on the University farm, covering eight years, show 

 cleai-ly the advantage of thick sowing of wheat. The advantage is 

 greatest in severe winters. The average yields per acre from the 

 different rales of seeding are as follows:

Experiments with Ihick and thin ])la]iting of rorn have lieciL carrieil 

 on eleven years at Purdue. The corn has been drilled in rows three 

 and two-thirds feet apart, the individual stalks standing about ten, 

 twelve, fourteen, sixteen and nineteen and one-half inches apart, re- 

 spectively, in the rows on the different plats. Here is a brief summary 

 of the results: 



1. Thick planting has produced more grain in favoraUe seasons 

 and much less grain in very dry seasons than thin planting. 



2. Thick planting has yielded more corn fodder than thin 

 planting. 



3. Medium thick planti)ig (stalks twelve inches apart) has pro- 

 duced the most corn fodder and also the greatest total yield of grain 

 and stalks. 



4. Jledium planting (stalks fourteen inches apart) has yielded 

 the most grain. 



Here are some interesting questions to which I hope you may find 

 correct answers. 



1. Why (lid thick planting in di-y seasons reduce the proportion of 

 grain ? 



2. AVhy did it not reduce the proportion of stalks? 



3. Why did the thinnest planting in dry seasons yield a greater 

 proportion of grain to stalks than any thicker rate? 



4. Why is it that, as a rule, severe drouths reduce the proportion 

 of grain in the corn crop? 



.5. AVhy do not drouths reduce the proportion of stalks T^ . 

 (I. -In growing corn to feed the entire crop of grain and stalks to 

 cattle, which of the above named rates of planting would you jtrefer? 

 7. If you were to plant two fields to com. one of which suffers
