Yields for 1932 are given in Table 3. Since 6 new \arieties were introduced 

 and 11 old ones dropped in 1932, the results can hardly be compared directly 

 with those of 1929-1931. Furthermore, a change in field technic makes direct 

 comparison between results of the two periods difficult. 



For the longer period, the five highest-ranking varieties were as follows: (1) Dun- 

 field, (2) Habaro, (3) Medium Green, (4) Harbinsoy, (5) Virginia. The high 

 yields and fine stems of Dunfield and Habaro make them preferable for hay. 

 The coarseness of the stems of Medium Green and Harbinsoy is a point against 

 these varieties for forage. All are suitable for green manure.
