March, 1917.] THE SOY BEAN IN NEW HAMPSHIRE. 17 



experiments. At the Tennessee Experiment Station* soy bean 

 and alfalfa hay were fed in conjunction with corn and cob meal to- 

 two lots of Jersey cows, four in each lot. The average milk 

 yield per lot for 30 days was 245 pounds in favor of the soy bean 

 ration and the fat yield for the same period from the soy bean 

 hay exceeded that from the alfalfa by 20.5 pounds. 



At the Ohio Experiment Stationf after trials in 1908 and 

 1909 it was concluded that soy bean hay can replace much of the 

 high-priced protein concentrates in the ration of the dairy cow. 



Soy bean hay is relished by all kinds of stock. The chief 

 objection to it is the coarse woody stems. The beans for hay 

 should either be drilled close to keep the stems fine or a fine 

 stemmed variety should be planted. 



Soy bean hay should be fed carefully at the start until the 

 animals become accustomed to it. The hay can be increased 

 from about three feeds per week to one feed per day to milch 

 cows and young stock. 



VARIETIES. 



The following is a list and brief description of some of the 

 leading varieties. 



Guelph or Medium Green (seeds, green). This variety is 

 a rank grower, highly valued for its forage. It will be mature 

 enough for silage in our state in about 90 days, but will be most 

 valuable at 110 days. All of these varieties have a cutting 

 period of three to four weeks during which time they might be 

 cut for silage. The cutting period for hay is much shorter, as 

 the stems get woody rapidly. 



Hollybrook (seeds, straw yellow). A variety maturing about 

 the same time as the Guelph and similar in habits of growth. 

 Although the analysis of this variety revealed a low percentage 

 of protein it is nevertheless a very satisfactory yielder of green- 

 forage and dry matter. 



Haberlandt (seeds, straw yellow). A variety about one week, 

 later than the Guelph. Does not grow as erect as the Guelph. 



Swan (seeds, straw yellow). Similar to the Haberlandt.
