grain the degree of flintiness is higher than is consistent with the quality of a 

 good barley for brewing purposes. Much damage is also sustained by lodging, 

 and in this particular the variety Princess was the least satisfactory, although 

 in every other way the best variety tested. 



Irrigation of barley, II. T. Nowell {Wyoming Sta. BuL 77, pi). 3-20, jAs. 3, 

 dgm. 1). — The value of barley as a feed and for brewing purposes is discussed, 

 and the results of experiments on the amount and method of applying water in 

 irrigating barley are reported. 



About 12 acres were divided into 6 plats and planted by a press drill with 

 approximately 90 lbs. per acre of Chevalier brewing barley on May 9 and 10. 

 The quantities of water used and the results are shown in the following table: 



Quantiti/ of water applied and results secured in groxving brewing barley. 



Each application of water appeared very slightly to delay the growth of the 

 crop, and this is thought as probably due to the lowering of the soil tempera- 

 ture through the use of cold water or to the displacement of the air from the 

 soil as it becomes saturated. 



The following table shows an approximate estimate of the complete cost of 

 growing Chevalier brewing barley : 



Estimate of cost and profit of growing breicing barley. 



In a series of experiments to compare the methods of irrigating barley one 

 plat was laid out for irrigation by the check method, a second for irrigation by 

 the furrow method, and a third was prepared for flood irrigation. Furrow 

 irrigation used less water and maintained the surface soil in a much looser 

 condition than either of the other methods. Under the check irrigation method 

 and the flood method the surface soil had a tendency to bake to a hard crust. 

 The initial cost of furrow irrigation was higher but the labor of irrigation less 

 than with the other methods. It is recommended that the furrows be not less 

 than 16 in. apart. At 8 in. apart the first cost is considered too large for the 

 practical farmer.
