REPORT OF CRANBERRY SUBSTATION FOR 1914. 101 



was resanded in the fall of 1911 and spring of 1912 and again in the fall 

 of 1914. 



The results with these plots in the amounts of fruit produced were not 

 at all conclusive. The results of the storage tests, however, with only- 

 one exception, agreed with those of former years in showing that resand- 

 ing greatly favors fungous diseases. 



Fertilizers. 



Most of the fertihzer plots on the station bog were given their 1914 

 applicatioTi on June 17 and 18. The lime was not applied to plot 11 until 

 July 17, and plot 12 went without fertilizer until the same date because 

 the muriate of potash was not delivered promptly. The plots were picked 

 with scoops on September 16 and 17, no distinct advantage in quantity 

 of fruit being shown by the fertilized areas as compared with the check 

 plots. The berries seemed so uniform in color and most other respects 

 that no records were made except of their quantity and size. Average 

 counts of berries in several cupful samples taken from each of the plots 

 did not show that the fertilizer had distinctly affected their size. 



Storage tests, beginning November 14 and ending on New Year's day, 

 were carried out with berries from each of the plots. These tests probably 

 were not as rehable as those of fomier j'ears because the berries were 

 run through a separator before they were stored. The results, however, 

 seem to show that the nitrate of soda distinctly impaired the keeping 

 quality, though the greater shrinkage of the fruit from the nitrate-treated 

 plots maj^ have been due to a greater loss of water during storage, rather 

 than to increased rotting, the berries perhaps being somewhat more 

 succulent. The year's experience with these plots and their fruit is shown 

 in detail in Table 4. 



Plots 1, 5, 9, 13, 17, 21, 22 and 2.3 are all untreated check plots. The 

 meanings of the fertilizer symbols used in the table are as follows : — 



O = Nothing. 



N = 100 pounds nitrate of soda per acre. 



P = 400 pounds acid phosphate per acre. 



K = 200 pounds high-grade sulfate of potash per acre. 



L = 1 ton of lime (slaked) per acre. 



Kcl = 200 pounds muriate of potash per acre. 



Nil = 150 pounds nitrate of soda per acre. 



Ng = 200 pounds nitrate of soda per acre. 



Pji = 600 pounds acid phosphate per acre. 



P2 = SOO pounds acid phosphate per acre. 



In combination they mean, for example, as follows: N2PK = 200 pounds 

 of nitrate of soda -1- 400 pounds of acid phosphate -f 200 pounds of high- 

 grade sulfate of potash per acre.
