CONSIDERATIONS OF SEED 57 



By sprouting the seed tubers, the Kansas Experiment 

 Station 1 have planted potatoes in March and lifted the 

 crop on June i . At the Rhode Island Experiment Sta- 

 tion 2 potatoes were held in a fairly well-lighted room 

 at a temperature of 60 to 75 F. for four to six weeks.

This often occurs when potatoes are left in sacks, barrels, or in piles in the 



cellar. As soon as sprouting begins, spread the tubers thinly on the barn 



floor, in the light, to check this waste of energy. 



In this time thick buds, one-half to an inch long and 

 one-quarter to three-eighths of an inch in diameter, 

 formed (Fig. 14). The potatoes may be held at this 

 stage for some weeks if necessary by lowering the tem- 

 perature. Early Rose potatoes weighing about three 

 ounces each were sprouted as described, and planted on 

 May i beside similar tubers which were unsprouted.
