Alfalfa. 



'231 



It is noticeable that up to this time the chief influence of the stable 

 manure had been to stimulate the growth of weeds, as seen by comparing 

 the figures in the column at the right. This increase was largely of 

 alsike and red clover — the seeds of which are supposed to have been in 

 the manure. The crowding of these weeds had hindered the growth of 

 the alfalfa as much as the manure had helped it. The fertilizer had 

 helped the growth both of alfalfa and weeds. It is also noticeable that 

 lime had helped the growth of alfalfa in every instance, and that up to 

 this date very little development of nodules had taken place on any of 

 the plats. 



The plats were clipped July 14, and on October 18 other areas were 

 selected and the plants taken up and examined as before. In this case 

 the work could not be promptly completed and weight of the dry plants 

 is taken instead of the fresh. Table No. 2 gives the data obtained by 

 this second study of the plats (in the " inoculation " column, o means no 

 inoculation; -f- abundant inoculation; -\ — [-, very abundant; — , very 

 little inoculation; i, one plant found with inoculation).
