24 SOY BEAN VARIETIES. 



rather too small for best results as a hay and silage crop, except where quick returns 

 are desired. The Kentucky Agricultural Experiment Station reports 5,^^ tons of green 

 fodder per acre, curing to U tons. In Ontario, Canada, the average height for four 

 years was 27 inches and average yield of green hay 8| tons. In 1903 the Kansas 

 Agricultural Experiment Station secured yields of 14^ to 15fo bushels of seed from 

 four different plats. All showed a high percentage of nondehiscence of the pods— 88 

 to 96 per cent. At the Massachusetts Agricultural Experiment Station the seed 

 yields have varied between 18 and 20 bushels in favorable years.

MANHATTAN. 



The Manhattan is a dwarf early variety with medium stems 15 to 24 inches high, 

 averaging about 20 inches, stocky, branches short and ascending; leaves medium to 

 large, dark green in color; pods numerous, 1^ to 2 inches long, three-eighths to seven- 

 sixteenths inch wide, 2 to commonly 3 seeded; seeds medium in size, round, broadly 

 elliptical in outline, 7 to 8 mm. wide, 7 to 9 mm. long, considerably flattened, rather 

 pale yellow with a slight greenish tinge, becoming paler with age, hilum brown. 



The Manhattan variety is early to medium early, requiring from ninety to one hun- 

 dred and ten days to reach maturity, the average being about one hundred to one hun- 

 dred and five days. It is too small to have much forage value, and its chief use will 

 be for an early seed crop, to which purpose it is fairly well adapted. Several yields of 

 from 14 to 16 bushels to the acre are recorded. 



This variety was named for the location of the Kansas Agricultural Experiment 

 Station, Manhattan, Kans., where the soy l^ean has been under extensive experimen- 

 tation for many years.

BUTTERBALL. 



An early or medium early variety, with short, stocky, unbranched stems, dark 

 foliage, and large yellow seeds. Plants low, 15 to 25 inches high, stems small to 

 medium, one-eighth to one-fourth inch in size at the base, with 2 to 5 short, stubby 

 branches near the base; leaves large, usually dark green. Pods broad, li to 2 inches 

 long, one-half inch wide, 2 or rarely 3 seeded. The seeds are large, 7 to 8^ mm. wide, 

 7 to 9 mm. long, spherical, pale lemon-yellow, somewhat shiny, becoming much paler 

 and duller with age, the hilum pale or slightly brownish. 



This variety is too small to have much value except for earliness and large size 

 of the seed. The last quality may entitle it to attention in V)reeding experiments. 

 It matures in ninety-five to on" hundred and ten days. Yields of 8| and 14| bushels 

 of seed to the acre are recorded.
