 statistically. 



Grimm alfalfa was lower in yield than any other variety. The stand ob- 

 tained for Grimm was relatively poor, and may partially account for 

 these results. However, recent yield data from other northeast states have 

 also shown that several new varieties are definitely better than Grimm. 



The varieties did not maintain the same relative rank in different years. 

 For example, Ontario Variegated was fourth in yield in 19.51 and 1952, 

 second in 1953, third in 1954, and second in 1955. Highest average yields 

 were obtained during the wet season of 1954. Figure 1 shows that the 

 stand was still good in the fifth season. 



As previously mentioned, five plots were seeded to bromegras^ alone, 

 and an additional set of five plots to a bromegrass-alfalfa mixture. Yields 

 of these plots were not included in the analysis since the chief purpose of
