CEREAL EXPERIMENTS AT THE AKRON FIELD STATION. 29 
Hannchen (C. I. No. 602) has produced the highest average yield 
per acre. Its average of 38.7 bushels is 0.7 bushel higher than that 
of Coast, C. I. No. 690 (ormerly grown and distributed as California 
Feed). Hanna (C. I. No. 226) ranks third, with an average yield of 
34.3 bushels. White Smyrna (C. I. No. 658) is the only variety 
recently introduced into the tests which shows promise of outyielding 
those already mentioned.

1 Yields computed at 48 pounds per bushel; actual weight about 56 pounds. 
The variety commonly called ‘‘Bald” or ‘‘White Hull-less” barley 
is here called Nepal, its proper name. Although naked barley has 
about the same bushel weight as wheat, it is here computed at 48 
pounds, in order that the naked varieties may be more easily com- 
pared with the hulled ones. On this basis the yield of the Nepal 
variety is 25.1 bushels. Pound for pound it is more valuable than 
hulled barley, as the latter contains from 10 to 12 per cent of hulls. 
Deducting for these, the 25.1 bushels of Nepal barley is nearly equal 
to 28.7 bushels of hulled barley. 
Winter barley has winterkilled to such an extent that the average 
yield is low. In two years out of six the winter barley has failed. 
The average yield for the six years is 8.3 bushels to the acre.
