Results of Experiment B. 



In this experiment, as was to be expected, the two plots VI A 

 and VI B showed very marked differences throughout the sea- 

 son. The corn germinated well and evenly. A full stand was 

 obtained on both plots. The corn in plot VI A grew faster and 

 made more even and ranker growth than that in VI B. On 

 June 19, 1909, the corn in the fertilized plot was about one-third 

 larger than that in the plot without fertilizer. On July 12, the 

 corn on the fertilized plot showed much ranker growth than 

 that on the unfertilized plot. There was, however, very little 

 difference in respect to earliness. About the same number of 

 plants showed tassels in the one plot as in the other. During 

 the latter part of the season the corn in the unfertilized plot 

 grew better relatively than it did during the first half of the 

 season. This was undoubtedly due to the manure which the 

 plants were able to use about this time. When the corn was 

 ready for harvest the plants in the unfertilized plot were about 

 one foot shorter on the average than the rest of the field. 

 There was practically no difference in the time of maturity. 

 Both plots were ready for the factory and for seed at the same 

 time. From this experiment it would seem that the amount of 

 fertilizer has very little effect upon the time of maturity of this 

 corn at least when grown under conditions to which it is locally 

 well adjusted. 



With regard to the yield, however, the case is different. 

 Table 11 gives a summary of these two plots with respect to 

 yield.
