In 1913 the yields were low. The highest yield, 13.2 bushels 

 per acre, was obtained from the 2-peck rate. In 1914 the highest 

 yield, 11.9 bushels per acre, was obtained from the 4-peck and 5-peck 

 rates. In 1915 the highest yield was 34.9 bushels per acre, obtained 

 from the 7-peck rate, though the yield from the 5-peck rate was only 

 slightly lower. The results to date show that a thin seeding of 2 to 

 4 pecks per acre has given the best average yields in the 3-year period. 



DATE-OP-SEEDING EXPERIMENT. 



A date-of-seeding experiment with the Svanhals barley has been, 

 conducted at the Cheyenne Experiment Farm during the 3-year 

 period, 1913 to 1915, inclusive. Plats have been sown April 15, 

 May 1, and May 15 each year. The amiual and average yields 

 obtained from this test are shown in Table XXIII.

Yields in 1913 and 1914 were low, with a slight advantage for the 

 early seeding. In 1915 the yields were much higher, the May 15 

 seeding giving the highest yield, 40.3 bushels per acre. The average 

 yields favor early seeding, between April 15 and May 1. 



EXPERIMENTS WITH FLAX. 



Flax is one of the common farm crops in eastern Wyoming, being 

 grown quite extensively on the newly broken prairie. However, flax 

 Is not grown as extensively as results indicate that it should be. 



VARIETAL EXPERIMENTS. 



Fourteen varieties of flax have been grown on the Cheyenne Experi- 

 ment Farm for a p(!riod (jf thre(! years and two additional varieties for 

 a period of two years. The annual and average yields obtained from 

 thes(! 10 vurieti(^s an; shown in Table XXTV.
