THE IRRIGATION AGE 



DRY LAND POTATOES. 



C. L. FITCH. 



Colorado Agricultural Experiment 

 Station, Fort Collins, Colo. 



Experience has proven that the 

 drylander should plant both early 

 and late varieties of potatoes, to 

 catch the season at one end or the 

 other. Early Ohios have been most 

 planted for early, but above the 

 ditch are apt to be rusty fleshed, 

 from soil heat in a dry summer. 

 Irish Cobblers are better in this 

 respect, and yield more in a good 

 year. Pearls mostly are planted 

 for late. 



It is a good plan on dry land to 

 mark the field both ways and to 

 plant the potatoes at the cross 

 mark, and cultivate them both 

 ways, so as to reduce hand work. 

 It is risky to plant on ground in 

 a dry year with a dried out subsoil, 

 but with a good spring and a sub- 

 soil in good condition, wide spac- 

 ing makes potatoes fairly sure, 

 where leaf roll has not appeared. 



There are many excellent dry- 

 land regions for potato growing in 

 the western half of Colorado, and 

 table lands of the N. E. have pro- 

 duced good crops. New settlers in 

 the plains in the southern part of 

 the states should be cautious, as 

 potatoes have been a complete fail- 

 ure in most places in that region. 



Dry lands, notably the Arkansas 

 divide, have suffered severely from 

 potato leaf roll, and new settlers 

 should make careful inquiry re- 

 garding their neighbors' experience 

 in 1911 and 1912 before giving 

 much land or work to potatoes. 



Nearly every newcomer seems to 

 have to learn for himself that we 

 have conditions and localities where 

 it is cheaper to purchase potatoes 

 at the store than to try to raise 

 them.
