Another method of obtaining slips is from 
cuttings from the ends of the vines. Take 
cuttings from 10 to 12 inches long, from the 
earliest planted or the most vigorous vines. 
Having removed all the leaves except those at 
the very tip, plant the cutting lying down with 
only an inch or two of the tip showing. The 
rows should be about three feet apart and the 
slips in the row 18 inches apart. The average 
yield is from 200 to 400 bushels per acre. 
Sweet potatoes suffer from several fungous 
diseases which are discussed in New Jersey Ex- 
periment Station bulletins on Sweet Potato Cul- 
ture. Leaf blight may be checked by the use 
of Bordeaux mixture, but rotation is the cure 
for tuber crop diseases.
