3 to 5 inches deep and 1 foot apart. An experiment to determine 
the value of this method as compared with ordinary drilling was con- 
ducted at the Georgia State College of Agriculture during the seven 
years 1911 and 1913 to 1918, inclusive. The Red Rustproof variety 
was used and the plots were one-hundredth acre in size and in dupli- 
cate. The data from this experiment are given in Table 14.

The annual yields shown in Table 14 indicate that there is little 
difference between the two methods in average or favorable years. 
The annual yields for 1918 indicate that in the colder years the open 
furrow provides better protection than ordinary drilling. In that 
year yields of 28.5 and 13.5 bushels, respectively, were obtained from 
the two methods. It is evident, however, that the open furrow will 
not give perfect protection, asin 1917, when conditions were so severe, 
oats sown by both methods were killed. 
METHOD OF SEED-BED PREPARATION 
An experiment to determine the best method of seed-bed prepara- 
tion for winter oats, in which plowing was compared with disking 
the land, was conducted at the Georgia State College of Agriculture 
during the six-year period from 1913 to 1918, inclusive. Disking 
makes it possible to prepare more land per day at less expense, thereby 
helping to get the crop in earlier. This experiment was conducted 
on land on which corn was grown during the summer. The corn was 
cut and shocked about September 1, and one seed bed was prepared 
by double disking with a disk harrow and another by plowing and 
harrowing. The seed was sown with a grain drill. The variety used 
was the Red Rustproof (Appler), and duplicate hundredth-acre plots 
were sown. The results obtained from this experiment are given in 
Table 15. |
