EXPERIMENTS WITH MINOR CEREALS. 



RYE. 



Winter rye has been grown in field plats for two years on the 

 Akron Field Station. The average yield in the two years was 26.1 

 bushels per acre. This is much below the wheat yields in the same 

 years. The blooming of the flowers at a time when dry, hot winds 

 are common causes a partial sterihty of the heads and a resultant 

 reduction in yield. At present rye is not grown as a grain crop, 

 but as a catch crop for forage. 



EMMER. ! 



Winter emmer has been sown each of the eight years, 1908 to 

 1915, inclusive. The crops of 1909 and 1915 were failures. The

highest yield, 29.5 bushels, was produced in 1908. The 8-year aver- 

 age yield of Black Winter emmer (C. I. No. 2337) is 14.2 bushels 

 per acre. Good stands are usually obtained, but a high percentage 

 of winterkilling occurs, and low yields result. Winter emmer can 

 not be recommended for this district. 



White Spring emmer (C. I. No. 1524) has given fair yields in each 

 of the eight years it has been grown. The lowest yield, 11.1 bush- 

 els, was produced in 1910, and the highest yiidd, 09 bushels, in 1915. 

 The average aero yield has been 30.3 bushels. Spring emmer is 

 therefore a fair producer, but it has not boon a close competitor of 

 either wheat or barley.
