SUGAE. 



CONDITIONS INFLUENCING AMOUNT OF SUGAR IN 

 ; BEETS. 



Numerous conditions exercise a marked influence upon the 

 development of sugar in beets. Among the most important, we 

 may mention the following: 



1. Climate. 



2. Varietv of Beet. 



3. Quality of seed. 



4. Plant-food. 



5. Soil. 



6. Methods of cultivation. 



7. Size. 



8. Time of planting and harvesting. 



1. Climate. 



Temperature. — According to extended experience, it has been 

 shown that the highest amount of beet sugar is commonly 

 obtained in places whose mean summer temperature is about 

 70° F. 



Rainfall. — The amount of rainfall most favorable to the devel- 

 opment of sugar in beets is from two to four inches a month dur- 

 ing the summer. Midsummer drought works injury to the de- 

 velopment of sugar beets. Rains after the crop has matured and 

 before it is harvested may start a new growth of the beets, bv 

 which the percentage of sugar is materially lowered.
