YIELD AND GROWTH FROM FERTILIZER TREATMENTS (AFTER HEDRICK) 



It will be seen from these data that the fertilizers have 

 resulted in practically no increases in growth or yield of 

 the trees. Neither was there a difference in the uniformity 

 of the crops or in the maturity, keeping quality, texture, or 

 flavor of the fruit. It is recorded that the size of the apples 

 was slightly increased by the treatments and that the foli- 

 age was greener during the last season of the experiment 

 where nitrogen had been applied. But the conclusion was 

 drawn that "The trees in this experiment would have been 

 practically as well off had not an ounce of fertilizer been ap- 

 plied to them." 



After twenty years' work in this same orchard, the con- 

 clusions are drawn that, "In general there are so many in- 

 conclusive or contradictory results that no conclusion of 

 practical value can be drawn from the yields. Heavy appli- 

 cations of nitrogen in a complete fertilizer and in manure 

 have not increased tree growth. When the costs are con-
