Field Tests of Glover and Alfalfa Seeds Collected in 1929 



Conducted in Conjunction with tlie Department of Agronomy, M. A. C. 



Thirty-one samples of clover and alfalfa seeds were planted in rod rows for 

 variety testing on July 5, 1929. All plantings grew very well considering the 

 extremely dry season. Difficulty in securing adequate stands of two red clovers 

 and one sweet clover was traced to poor germination. The germination in the 

 laboratory was 46, 68 and 52 per cent respectively, yet in the field even second 

 and third plantings failed to give average stands. This indicates the impor- 

 tance of a germination of at least 70 per cent under laboratory conditions before 

 the seed can be expected to produce satisfactory growth in the field. 



Observations on the varieties were made twice during the 1930 season, on 

 the first and second cuttings, except the sweet clover varieties which were cut 

 but once. Following are the results of the variety tests.
