Alfalfa.

An inspection of Table No. 2 shows that the weed growth on ah 

 plats dressed with stable manure continues to be vigorous, that inoculating 

 the seed with cultures from U. S. Department of Agriculture produced 

 no appreciable improvement either in growth of plant or abundance of 

 nodules while soil alone even surpassed manure alone, that commercial 

 fertilizer which promised so well early in the season failed to maintain 

 its position to the end, that the benefit produced by lime is still very 

 apparent, and finally that the combination of stable manure, lime and 

 soil inoculation alone produced results that promise ultimate success in 

 alfalfa growing on this soil. 



In order that the significance of the data given in Tables i and 2 

 may be made more easy of comprehension. Tables 3, 4, 5 and 6 have been 

 compiled from them, each presenting a single feature for consideration. 

 Table No. 3 shows how the vigor of the plants as measured by their average 

 weight and average length was affected by manure, lime and inoculation. 

 Table No. 4 shows the influence of the application of lime on the number 

 and vigor of alfalfa plants and weeds on an area 12x18 inches. Table 

 No. 5 shows the relative abundance of nodules developed by inoculation 

 with soil, inoculation of seed by cultures and no inoculation. Table No. 

 6 shows the influence of a dressing of stable manure on weed production 

 on these plats.
