LEGUMES FOR SEED 23 1 



den Vine field pea produced stem vines averaging 9.5 feet in 

 length. 1 The Utah Station found with the Golden Vine variety 

 the greatest yield of both green and dry matter was when the 

 plant was in flower, the yield of water-free substance being: 

 whole plant, 4,997, leaves 2,347, stalks 1,391, and flowers 259 

 pounds. Two weeks later, when the pods were mature, the 

 yield of water-free substance was: whole plant 3,496, leaves 

 1,699, stalks 698, and pods 1,108 pounds. The percentage of 

 leaves decreased from youth to maturity; the percentage of 

 stalk increased until the pods began to form, when it then 

 decreased. 2 



276. VARIETIES. Among 33 varieties at the Minnesota Station, the best 

 yield of grain was obtained from White Canada Field, 20.3 bushels. Other 

 varieties, Alpha, Blue Prussian, Crown, and Green Canada Field, held good 

 rank, none of these falling below 17 bushels per acre. The lowest yield of 

 any variety was 11.1 bushels. Most of the varieties matured within 90 days, 

 the extremes being 79 and 100 days. In fourteen tests of two varieties, the 

 Canada Station found Early Britain to lead with 32.6 bushels of grain and 

 1.7 tons of straw per acre. 3 After an experience with about 100 varieties 

 lasting over a period of fifteen years, the Ontario Station * makes the following 

 recommendations, based principally on grain production: for very rich soil, 

 White Wonder; for soil of medium quality, Early Britain and New Canadian 

 Beauty; for poorer soils, Prussian Blue and Tall White Marrowfat. Among 

 the most productive sorts grown for five years at the Canadian Experimental 

 Farms are Golden Vine, Victoria, Mackay, White Wonder, Prince, Canada 

 Beauty and Prussian Blue. 5 



Of three varieties tested by the Massachusetts Hatch Station, there was 

 little difference in yield of green pea vine between Prussian Blue and Canada 

 Beauty, while English Gray was rather low. At the Wyoming Station, Golden 

 Vine and Mexican matured in August, while White Canadian and Green 

 Canadian matured in September. The varieties most frequently mentioned 

 by other stations are Golden Vine, Prussian Blue and Canada Beauty.
