1 Danger of soil blowing on experimental plats in 1914 delayed seeding until it was too late to mature grain 
2 H= Destroyed by hail. 
The yields show very consistently an advantage of fall plowing over 
spring plowing, irrespective of the kind of stubble that is plowed. 
They also show wheat doing better after oats than after wheat, 
whether the stubble is plowed in the fall or in the spring. 
Very small gains have attended both subsoiling and opening over 
winter with a lister instead of plowing. 
Disking corn ground has been better than plowing it. 
The best average results have been obtained from summer tillage. 
The gain of this method over disked corn ground, the next highest
