CORN. 61 



wherever it is applied, there is a considerable increase in 

 the yield. 



The illustrations on page 62 show the results of a series 

 of experiments with corn, conducted by Prof. W. P. Brooks 

 of the Massachusetts Experiment Station. For the pur- 

 pose of comparison the yields of two plots of exactly the 

 same size are given side by side. 



The first illustration shows the yield of corn from 

 two plots, each -fo of an acre : 



The one marked "no fertilizer" produced 117 pounds 

 of stover and 123 pounds of ear corn. The other plots 

 received acid phosphate and muriate of potash and yielded 

 ror pounds of stover and 198 pounds of ear corn, that is, 

 an increase of 61 per cent, over the plot not fertilized 



The lower illustration is interesting, as giving a 

 comparison between the effects of chemical fertilizers and 

 barnyard manure on corn. 



The plot receiving barnyard manure produced 188 

 pounds of stover and 219 pounds of ear corn. The plot, 

 which received chemical fertilizers (consisting of nitrate 

 of soda, acid phosphate and muriate of potash) produced 

 204 pounds of ear corn, or about the same results as with 

 the stable manure. 



The illustration on page 63 is even more valuable as 

 showing the marked effects of the potash on corn. 



Here we have two plots of same size, one unfertilized 

 and another fertilized with muriate of potash. Note the 

 wonderful difference in the yield of corn. The yield from
