BULLETIN 430, TJ. S. DEPARTMENT OF AGEICIJLTUEE. 



If the fall is wet, late-sown plats may continue green until destroyed 

 by frost. This condition was observed in the vicinity of Archer in 

 the fall of 1913. It wiU require years of testing to determine the best 

 date to sow flax. Until more definite data are available it appears 

 that sowing between May 15 and June 1 will be satisfactory.

EXPERIMENTS WITH MINOR GRAIN CROPS. 



The minor cereals, including proso, foxtail piillet, grain sorghums, 

 com, and buckwheat, have been tested at the Cheyenne Experiment 

 Farm during the 3-year period, 1913 to 1915, inclusive. Each of 

 these cereals will be discussed briefly in the following paragraphs. 



PROSO AND FOXTAIL MILLET. 



Proso (bro(?m-corn millet or hog millet) is grown for grain for feed- 

 ing purposes, while foxtail millet is grown largely for hay. Proso is 

 not grown extensively in eastern Wyoming, though it is fairly well 

 adapted to the soil and climatic conditions prevailing in this district. 



Eight prosos and two foxtail millets have been grown at the 

 Cheyenne Experiment Farm during the 3-year period, 1913 to 1915, 

 inclusive. The annual and average yields of the 10 millet varieties 

 are shown in Table XXVII. 



In 1913 the millets were grown in rows 132 feet long and spaced 

 3 feet apart on fall-plowed breaking. The summer was dry, but fair 

 yields were obtained. In 1914 the millets were grown on fallow in 

 twentieth-acre plats in rows 3 feet apart. The summer was dry and 

 the yields obtained were low. In 1915 the miUets were grown in 

 twentieth-acre plats on double-disked corn ground. The yields 

 obtained were low in spite of the better season. 



The foxtail varieties have given higher average yields than the 

 prosos. The proso yields have been materially reduced each year by 

 shattering at and before harvest time. Birds are very fond of proso 

 seed and have eaten large quantities before thrashing. A con-
