CEEEAL EXPERIMENTS ON THE CHEYENNE EXPERIMENT FARM. 



19 



In 1914 the spring-wheat varieties were sown on April 21 and 22 

 in tenth-acre plats on spring-plowed fallow land. Good stands were 

 obtained on all plats. The spring was late, cool, and wet. The pre- 

 cipitation for the growing season was below normal. A hailstorm on 

 June 14 damaged the spring wheat to some extent, Dm-ing both 

 1913 and 1914 the crop prospects were excellent until about June 1, 

 when the crops began to suffer from drought. The yields in 

 1914, as shown in Table X, ranged from 3.1 bushels per acre for 

 Crossbred (C. I. No. 3695) to 13 bushels per acre for Kubanka 

 (C. I. No. 1516). The average yield of the 14 durum varieties was 12 

 bushels, while the average yield of the 18 spring common varieties 

 was 8.9 bushels per acre. The best variety of durum yielded 13 

 bushels, or 2.6 bushels more than the best common wheat.
