The Chevalier II is taller, later, and produces much higher yields 

 than the other varieties.

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.
