4. Obtaining seed. — Large yields of potatoes cannot be ob- 

 tained without the use of good seed. By good seed is meant 

 sohd, dormant, disease-free tubers, selected from high yielding 

 plants. It is not often possible to buy seed that is satisfactory 

 in all these respects, especially with reference to high yielding 

 plants. This point, however, should have consideration in the 

 home project, if potatoes are to be grown the following year. 

 Numerous experiments have shown that it pays to select seed 

 from healthy plants producing heavy crops of large, smooth 

 tubers. This is a matter which requires considerable time, but 

 it is time profitably spent. 



When it is necessary to purchase seed, extreme care should be 

 exercised. A common practice is to plant seed grown in a more 

 northern section, but such seed has little if any advantage over 

 home-grown seed provided the latter is produced intelligently and 

 stored under the most favorable conditions. If the tubers are 

 allowed to wither and produce long sprouts before they are planted, 

 satisfactory results cannot be expected.
