A Study op the Crop for 1903. 



The first crop was gathered in June 

 and July of 1903, and was about 88 per 

 cent, of the total possible crop. Dia- 

 gram III. gives the total number, and 

 number of different sizes of pines taken 

 from each plot ; the total number in the 

 sections ; and the total number in the 

 plots occupying relatively the same posi- 

 tion in the sections counting from left 

 to right across the entire plot, for the 

 years 1903, 1904 and 1905. A careful study 

 of the crop for 1903 will yield some very 

 interesting insults. In at least half the 

 sections there is a slight increase in the 

 total number of pines from the first to 

 the third plot of the sections. On the 

 other hand there is but little difference 

 between the number obtained from the 

 third and fourth plots of the sections, 

 indicating, it would seem, that the limit 

 of amount of plant-food has been reached 

 with the quantity applied to the third 

 plot in each section, this amount as al- 

 ready stated being the same for all plots 

 occupying the same relative position in 

 the sections, reading from left to right. 

 As further proof of this, the plauts of 

 the third plot in the sections have al- 

 most uniformly appeared as large, stronlg 

 and healthy as those of the fourth plot, 

 and in some instances they have been 

 superior. By again referring to Diagram 



II. it will be seen that the third plot in 



all the sections, except those introduced 

 for special purposes, received each year 

 the equivalent of 3,750 pounds per acre 

 of a fertilizer analyzing 4 per cent, avail- 

 able phosphoric acid, 5 percent, nitrogen 

 and 10 per cent, potash, but in most 

 cases representing a different source for 

 at least one of the constituents. From 

 the same diagram it will be seen that 

 the fourth plot of the sections received 

 4,500 pounds per acre of the same ferti- 

 lizer. Judging, therefore, by the general 

 appearance, and also from the results 

 obtained from the plots, we are ready to 

 conclude that 3,750 pounds per acre, of a 

 fertilizer analyzing as above, about ap- 

 proaches the limit for profitable results. 



And as we have already shown by 

 section L., plot 47, that a mixture of 

 bone, blood and high grade sulphate, 

 with a percentage very closely approach- 

 ing the 4, 5, 10 percentage which was 

 adopted as the standard, and 3750 pounds 

 to the acre, gave slightly better results 

 than any of the other percentages tried, 

 it seems safe to conclude that on the 

 third plot of the sections we have the 

 quantity and percentage of a fertilizer 

 that will, in general, give the best results 

 with pineapples on the East Coast of 

 Florida, the proper materials, of course, 

 being selected-
