Bulletin 267. 



Comparing the above data with that of 1907 it will be seen that 

 temperature and moisture conditions were almost completely reversed. 

 Though rainfall was scant during June while the young mangel plants 

 were becoming established, the months of July and August brought 

 abundant rains, and the months of September and October were suf- 

 ficiently dry to insure sound maturity in the mangels when harvested. 



The crop was pulled on October 12th and 13th. For the dry matter 

 determinations five representative roots from each plat were selected. 

 The treatment of, and results from each plat are shown in the follow- 

 ing table:
