A Fertility Program for Celery Production


seem also to indicate that in good celery years, such as 1931-32
and 1937-38, a fertilizer analyzing even higher than 12% potash
applied at the rate of one ton to the acre before planting (more
than 240 pounds of K0O per acre) might be beneficial, but a
later discussion of the yields from Area 2 will show that a
higher application will probably not be advantageous from the
commercial standpoint in the average year.

 Fig. 7.-The influence of different amounts of potash (KzO) fertilizers on five-year
average yields of marketable celery produced per acre on Area 2 at the Everglades Experi-
ment Station. The different amounts of potash applied were tested at each of three levels
of phosphate (POs). The yield represented by the figures is given in terms of the number of
field-trimmed crates produced per acre. (Yield data for the five separate years for all of these
comparisons are listed in Table 7 in the appendix.)

 Fig. 8.-The influence of different amounts of potash (KeO) fertilizers on the yield of
marketable celery produced per acre for two crops grown on Area 3. The different amounts
of potash applied were tested at each of three levels of phosphate (P2Os). The yield repre-
sented by the figures is given in terms of the number of field-trimmed crates produced
per acre.
