Growth of Trees. 



When we examine the twig growth in this orchard we find that 

 it parallels the yield in the first five plots only, for when we reach 

 the fertilized ones (6-10) we find that they have been materially 

 affected by the treatments. Here we find that at no time in the 

 ten years have the trees in any of the unfertilized plots grown as 

 much as those in the fertilized ones. But in the past five years 

 the increase in the latter plots has been much more noticeable. 

 The following figures give the difference between the best growing 

 unfertilized and fertilized plots each year. This of course would 

 not always be the same plot in either case as shown by Table No. 

 5, but it brings out the growing difference between the two sets of 

 plots as the experiment continues. 



Difference in Inches Between the Best Growing Unfertilized and Fertilized 



Plots Each Year.
