EXPERIMENT STATION REPORTS. 243 



Europe, including Tystofte from Denmark, Broad red and Montgomery 

 red from Wales, and a Hamburg strain, were compared and none found 

 to be superior to Michigan seed. 



A comparison of the different strains of sweet clover: 



In this test the biennial yellow yielded somewhat less, approximately 

 two-thirds, as much as the biennial white sweet clover. 



It was from seven to ten days later than the biennial white and had 

 a smaller stem and finer leaf. The Early Dwarf also known as the 

 Grundy County Illinois White Sweet Clover was finer stemmed than 

 the common biennial white. 



Hubam or annual white sweet clover was found to give about the same 

 yield as the biennial white when sown and harvested the same season. 

 The dry matter per acre produced by the root system of the biennial 

 white was materially greater than that produced by the Hubam. 



For pasture and green manuring the biennial white strain is to be 

 recommended, while for hay production the Early Dwarf due to its 

 fine stem deserves further consideration. 



Soybean variety test: 



A number of soybean varieties have been tested for both forage and 

 seed production. The Mauchu gave the highest yield of both seed and 

 forage. Other varieties worthy of mention are the Ito San and Black 

 Eyebrow. 



The comparative adaptability of different species of legumes to muck, 

 sand and sandy loam : 



The different species of Trifolium such as Pratense, Subterranean, 

 Dubium, Panonicum, Fragiferum, Hybridum and Repense as well as 

 different species of Lespedeza, Lotus, Lupinus, Melilotus, Medicago, 

 Poterium and Anthylis are being studied. Project started spring of 

 1923. 



Mammoth clover: 



A study of the plant characteristics of a hundred lots of Mammoth 

 Red clover secured from various sections of the state. 



White clover studies : 



A study of the plant characteristics of a number of white clover strains 

 including English wild white. 



A study of the value of alfalfa seed from the various production 

 centers : 



The variegated strains, especially Hardigan and Grimm were found 

 to be superior to any of the common strains. The northern grown com- 

 mon strains, however, were far superior'to the southern grown common, 

 such as Arizona common and Hairy Peruvian.
