_ The varieties of the 6-rowed group were fully headed about July 10, 
and those of the 2-rowed group about July 15. The 6-rowed group 
reached maturity about August 2, and the 2-rowed group about 
August 8. There has been little difference in the height attained 
by the different varieties. The 2-rowed varieties have tested con- 
siderably higher in weight per bushel than the 6-rowed hulled 
varieties. ‘The 2-rowed group has yielded higher than either of the 
other groups. All varieties have produced about the same quantity 
of straw per acre.
