White Australian 



of plots of different varieties were seeded at various times in 1913, 

 1914, and 1915. Table LV records the results and indicates the de- 

 sirability of planting- in August or early in September. 



Table LIII indicates a heavy production of straw, compared 

 \\ith the yield of grain in 1914. This was probably due to the wet 

 sprang of 1914 and to thick seeding, the stimulated vegetative 

 growth utilizing available moisture from the soil to such an extent 

 that, upon fruiting, there was insufficient moisture satisfactorily to 

 mature the grain, which was light and shrivelled. While the grain 

 produced in 1914 was insufficient to insure reasonable profits, the 

 possibilities of w^heat as a hay crop are indicated. 



The production of winter wheat on dry farms in the Great 

 Plains and in the Northwest is usually considered the most profit- 

 able branch of the business. Persistent trials with some of the 

 hardiest varieties, however, have failed to indicate that wheat can 

 be profitably grown in the Prescott vicinity without irrigation. 

 Serious winter killing occurs even though the minimum tempera- 

 tures of winter are seldom very low. Plots planted in early fall 

 occasionally return profitable yields when the snowfall in winter is 

 sufficient and constant enough to prevent winter killing. Wheat 

 should be seeded thinly on dry farms, thirty-five pounds per acre 

 being sufficient. 



Oats: In the fall of 1912 two varieties of oats, Texas Red, and
