Early Brown — Plant characteristics cannot be distinguished from Ito 

 San. Seed of light brown color and medium size. 



Black Eyehroic — Very similar to the Ito San in plant characteristics 

 and time of maturity. Seed are easily distinguished by having an olive 

 green underbody with dark saddle. 



HoUyhrook — One of the best mediums late maturing varieties, matur- 

 ing from 125 to 135 days. Pubescence gray and the flowers white. Seed 

 are straw yellow with a light brown seed scar, and are smaller than 

 above mentioned varieties and much more flattened. 



Early Black — For northern Michigan the Early Black is better adapted 

 than the varieties above listed, being earlier in maturing. This is a black 

 seeded variety. Due to its earliness the plant does not grow very tall 

 nor rank. 



Soybean culture is dealt with in Special bulletin No. 100, Michigan 

 Experiment Statiooi. 



CLOVER. 



Michigan grown red, alsike, and mammoth clover is more dependable 

 than imported seed, much of which may have been produced in mild cli- 

 mates and is hence su'sceptible to winter killing. 



SWEET CLOVER. 



Michigan grown white blossomed biennial sweet clover gives best re- 

 sults for hay, pasturage, and soil improvement as compared to other 

 biennial types. (Circular Bulletin No. 46, Michigan Agricultural Exper- 

 iment Station, East Lansing.) 



The yellow blossomed sweet clover (biennial) is slowly gaining favor 

 for pasturage purposes (Michigan Experiment Station, Circular No. 46 

 "Sweet Clover"). 



HUBAM CLOVER. 



Hubam clover — annual-white sweet clover — ^makes its entire growth 

 in a single season. The seed is apparently identical in appearance to the 

 ibiennial sweet clover seed, and it is therefore important that field-inspect- 

 ed and certified seed produced in Michigan be grown. 



In 1921 thirty bushels of seed, at that time selling on the market from 

 |5.00 to $20.00 per pound, was distributed to Michigan farmers and seed 

 growers from the Farm Crops Department increase plats, through the 

 Michigan Crop Improvement Association, at $1.00 per pound for increase 

 purposes and ten bushels used in experiments to deteinnine the real value 

 of this new crop (Circular Bulletin No. 45, Michigan Agricultural Experi- 

 ment Station, East Lansing). 



VETCH. 



Hairy vetch or wdnter vetch is grown for seed purposes to a greater ex- 

 nt in Mi 

 demanded. 



tent in Michigan than any otlier state. Michigan grown seed should be 



BUCKWHEAT. 



The Japanese is conceded to be the highest yielding type. It is a large 

 black seeded variety and makes the largest gi'owth in the field. The Silver 

 Hull and Gray are smaller types and do not make quite as large a growth.
