CEREAL EXPERIMENTS AT THE AKROISr FIELD STATION. 



21 



In the Fife group, Ghirka Spring is the only variety that has been 

 grown dui'ing the entire eight years. It has given a lower yield than 

 the durums, and Table XIV shows that the weight per bushel is 

 about 2 pounds less. The Bluestem group has not been tested ex- 

 tensively, but the yields obtained are not especially promising. The

varieties of the Preston group have shown their abihty to yield well 

 in dry seasons, but the average for the eight years is low. Table 

 XIV shows that Erivan (C. I. No, 2397) has been ripe an average of 

 four days before any other variety, but the average weight per 

 bushel is only 56 pounds.
