442 THE APPLE 



The records for the twelve years were as follows : 



iSgj. Slight improvement was noted in the color of all the varieties on 

 the treated sections. Even the Roxbury was smoother and more highly colored 

 on the treated than on the untreated section. 



1894. Fall Pippins were smoother and fairer on the treated plats. Bald- 

 wins showed but little difference and that in favor of the untreated trees. 

 Rhode Island Greenings had a riper appearance, more yellow, and a tinge 

 of red on the treated plats. No difference discernible with the Northern Spy 

 and the Roxbury. The results for this year were not at all uniform. 



1S95. Effects were not more noticeable in this season than in the previous 

 one, Rhode Island Greenings and Northern Spies showing the best color in 

 the untreated plats, and Baldwins and Roxburys the highest color in the 

 treated plats. No difference was noted between the plats of Fall Pippins. 



i8q6. Colors developed as well on the untreated plats as on the treated. 



i8gy. The crop was comparatively small and poorly colored on both the 

 treated and the untreated plats, without noticeable difference. 



1898. Effects were not at all uniform, the product of the trees in the 

 same plats differing as much as the products from the different plats. 



i8qq. Slight improvement was shown in the color of Baldwins and North- 

 ern Spies (the red sorts), but no difference in Rhode Island Greenings, Fall 

 Pippins, and Roxburys (the green varieties). 



/goo. No differences could be noted. 



igoi. A small crop of undersized fruit, all poorly colored and showing no 

 difference in favor of either set of plats. 



IQ02. All the treated plats showed more brilliant colors, though the differ- 

 ences could scarcely be noted in the green varieties. 



1903. No crop. 



1904. The differences were slight and variable and not to be counted in 

 favor of either the treated or the untreated trees. 



Taken as a whole the results were disappointing. They lacked 

 uniformity, and were not decided enough in a sufficient number 

 of the twelve seasons to enable the Geneva Station to state that 

 the addition of the substances applied heightened the color of 

 apples under the conditions of this experiment. Not only did the 

 results vary from season to season, but varieties varied greatly in 

 the same season, and in some cases the same variety colored 

 differently in plats receiving the same treatment. When we con- 

 sider the number of factors which are known to influence color 

 in fruit we cannot assume with any degree of certainty that the 

 results described above show that the addition of these fertilizers 

 changed the color of the fruit in any season. Since exposure to
