pense. To produce uniform moisture conditions 

 in the soil is the secret of successful irrigation, and 

 this is the absolutely essential condition for the 

 most profitable potato growing under irrigation/' 



OREGON 



Oregon has earned an enviable reputation for 

 quality of potatoes produced, and Oregon Bur- 

 banks are very popular as seed tocks in California 

 and elsewhere. 



The following description of Oregon conditions 

 is by Prof. H. D. Scudder, Professor of Agronomy 

 in the Oregon Agricultural College at Corvallis: 



"The length of our growing season for potatoes 

 is about seven months. Potatoes are generally 

 planted the first two weeks in April and harvest is 

 completed during the month of October. 



"The soils most commonly used for the potato 

 crop here are sandy loams along the river bottoms 

 and silt loams on the valley floor and on the hill- 

 sides. Both these types of soil produce a very fine 

 quality of potatoes and, where properly handled, 

 nearly the same yields, the sandy loams, of course, 

 maturing the potatoes earlier and giving a larger 

 yield if anything, as a rule. The silt loams, on the 

 other hand, especially on the red hill lands, pro- 

 dnce a very fine quality of potato. 



"The chief potato district in the state is the 

 Willamette Valley, especially at its lower or north- 

 ern end. The Umpqua Valley and the Rogue 

 River Valley also are potato-growing districts, al- 

 though of lesser importance. 



"All our potato seed is home-grown. The chief 

 varieties are the Burbank and American Wondei,
