NURSERY EXPERIMENTS. 
About 35 varieties of barley, representing a wide range of types, 
were grown in 17-foot rows under irrigation in 1917 and 1919. The

object was to observe the behavior of the varieties under irrigated 
conditions. In general the late varieties produced the highest yields, 
which was in accordance with the results from the plat experiments. 
Further tests would be necessary to determine definitely the yields 
in comparison with the varieties grown in plats. 
EXPERIMENTS WITH MINOR CEREALS. 
SPRING EMMER. 
One variety of spring emmer, Vernal (White Spring), has been 
grown under irrigation each year in comparison with either the 
barley or oat varieties. The soil and preparation have been the 
same each year for both oats and barley, and usually spring wheat 
also, so that these crops can be compared directly with the emmer.
