THE POTATO 407 



sown in the fall and plowed under when twelve or 

 twenty inches high early in the spring. The vetch, 

 on account of its very high nitrogen content and 

 nitrogen gathering ability, makes, of course, a 

 wonderfully good covering and green manuring 

 crop. 



'*The size of the farms on which potatoes are 

 grown in Oregon is about 100 acres, and the 

 potato field is anywhere from five to sixty acres 

 in size. A ten-acre field is generally considered 

 a pretty good size field of potatoes, and forty 

 or fifty acre potato fields are only had by those 

 growers who are making a speciality of this 

 product. 



"The big growers are beginning to use system in 

 the culture and marketing of this crop, as well as 

 using rotations which will keep the ground in the 

 best condition. One of our best growers is using 

 that old and everywhere very successful rotation 

 of clover, followed by potatoes, followed by wheat, 

 the first crop of clover being cut and left on the 

 ground, and the second crop harvested for seed, the 

 field being plowed early in the spring for potatoes. 

 There are other rotations equally as good, but there 

 are no special ones that have as yet been widely 

 adopted. 



"Altogether, potato growing in Oregon is a very 

 profitable industry, especially so where modern 

 methods are employed and rotations are used. 

 Year in and year out the market is high when com- 

 pared with the potato market elsewhere and as yet 

 no such thing as a potato disease or insect pest is 

 known. As time goes on I think this crop will be 

 more widely and intensively grown and one which 

 will always prove excellent for including in rota- 

 tions throughout Oregon. "
