212 MAINE AGRICULTURAL EXPERIMENT STATION. 



SOJA BEAN. 



The soja bean plants were small and weak in every instance 

 and in no case were tubercles found except upon one plant from 

 soil inoculated with soja bean tubercles. (The tubercles used 

 were from last year's crop and were so dry it was feared they 

 would be of little value.) There was no noticeable difference 

 in the size and vigor of any of the plants. 



GENERAL CONCLUSION. 



The experiments thus far carried on at this Station do not 

 justify the recommendation of germ cultures for leguminous 

 crops. In no case did the culture of the specific germ of any 

 given species give better results than did a culture of a nearly 

 related type, and in most cases plants from untreated pots were 

 equally as vigorous and as heavy as were those from inoculated 

 soil.
