In this experiment the average yield of green clover was 

 14,039 pounds per acre with inoculation, and only 2,292 

 pounds without inoculation. Of cured hay the average was 

 4,057 pounds per acre with inoculation, and only 761 pounds 

 without, an increase of 8,296 pounds per acre. 



In regard to the cost of this beneficial treatment, Nitra- 

 gin is quoted at 62 cents per bottle in Germany, but costs us 

 $1.25, plus express from New York. One bottle is sufficient

for five-eighths of an acre, so that, including express from 

 New York, the cost of inoculation with Nitragin is about 

 $2.25 per acre. 



But material obtained at home without cost can be used 

 instead of costly Nitragin. The soil from a field where any 

 true clover (red, crimson, white or creeping clover, etc.) has 

 made a luxuriant growth and formed tubercles can be used to 

 inoculate clover seed, or soil from an old vetch field may be 

 used as inoculation material for vetch. In the following ex- 

 periment, first published in Alabama Station Bulletin No. 87, 

 such inexpensive inoculating material was used.
