4 MASS. EXPERIMENT STATION BULLETIN 309 



During 1929 and 1930 yields of both hay and seed were obtained for each 

 variet}^ but owing to comparatively low yields of seed it was decided to omit 

 these records in subsequent years. It was found, as might be expected, that 

 high grain and forage production characteristics of this crop were not combined 

 in a single variety, under the climatic conditions of this section.
