SUG.AR BEETS 



The water requirement of the sugar beet was again measured at Akron 

 in 1912. The ratio 321 ±8 was obtained on the basis of total dry matter 

 and 524±23 on the basis of the dry root (Table XI). This is about 15 

 per cent below the 191 1 value, a reduction in water requirement similar 

 to that shown by the other crops tested during the two seasons. The 

 sugar beet is an efficient plant in the use of water, being the equal of the 

 corn group in this respect.

COTTON 



Cotton was tested at Akron for the first time in 1912. Numerous 

 bolls set, though none opened. The plants grew slowly during the first 

 part of the season, owing probably to the cool nights. The observed 

 water-requirement ratio was 488 ±14 (Table XII).
