BARLEY 141 



ing eastern Oklahoma and Texas. The total barley 

 production is less than a million bushels. As the use of 

 barley for hay is likely to continue or even increase, a 

 hardy winter strain of hooded or awnless barley is desir- 

 able, to avoid injury to stock from swallowing the awns. 1 

 Rust is sometimes very damaging to barley in this dis- 

 trict (Fig. 47).

131. Northwestern Plains or two-row barley district. 

 There are included in this district western Sas- 

 katchewan, Alberta, eastern Montana, the western two- 

 thirds of North and South Dakota, northwestern Ne- 

 braska and eastern Wyoming. Generally the two-row 

 barleys give best results in this district, but much is yet 

 to be learned as to varieties in detail in all of the districts. 

 As the two-row varieties are tall and often nodding, they 

 tend to lodge worse than the six-row varieties in humid 

 areas, and are therefore adapted to the drier plains. 

 The larger part of the total North American production 

 of two-row barley is in this district. Tests at the Northern 

 Plains experiment stations and in Alberta and western 

 Saskatchewan, Canada, have resulted in considerably 

 better yields for two-row barley than for six-row. In 



1 The Arlington Awnless, developed by Derr (1910, pp. 473- 

 474), does not yet appear to be sufficiently hardy for fall seeding 

 in the northern border of the .winter barley area, though it ap- 

 pears to be a good variety.
