INDIVIDUAL GROVE REPORTS AND RANKINGS
Associate Agricultural Economist
Florida Agricultural Experiment Station
From the citrus costs and returns study now in progress through the co-
operation of citrus growers with the Florida Agricultural Extension Service, reports
are made each season giving averages by age groups for all groves. Other reports
are made on a county basis. Each cooperator is supplied with a copy of these re-
ports with which to compare his own individual report, which is made for each grove
The fiscal period of these records is September 1 through August 31 of the
succeeding calendar year. This period appears to be the best when analyzing records
for the most profitable practices on groves. In order to better measure results
obtained from these practices, the yield and financial returns are used from fruit
produced by the bloom of the period when production costs were incurred. This means
that costs incurred from September 1, 1947 through August 31, 1948 constitute the
costs for the fruit picked from September 1, 1948 through August 31, 1949. Such a
season is designated as the 1948-49 season, as the designation of the season.is for
the period of time in which the fruit was marketed. Such a procedure results in a
record kept for a grove for the period of September 1, 1948 through August 31, 1949
being tabulated as yield and returns for the season of 1948-49 and costs for the
season of 1949-50. This method results in the latest season tabulated being without
yield and returns.
The individual report includes costs and returns for the most recent sea-
son for which returns are available and costs for the following season, the returns
of which will not be available until the record of the grove has been completed for
the subsequent season. This report is as outlined in the form on the following page.
The number of the record book used is indicated for each of the two seasons of the
report; Grove acreage is shown in both instances to indicate any change. The aver-
age age of the grove is one year older in the most recent season if there have
/ been no additional plantings of trees. The age is the number of years elapsed from
time of setting the trees to the calendar year of bloom for crop designated.
The fruit yield is taken to be the number of boxes of fruit harvested. In
case some of the fruit is left on the trees, the actual yield is in excess of the
number of boxes harvested but the fruit harvested constitutes the commercial yield.
Fruit harvested is indicated for the first season of the report in total for the
.grove and per-acre. The 5 items of costs-labor, power, and equipment, fertilizer
materials, spray and dust materials, taxes, and miscellaneous--constitute total
operating costs. By adding to this total the interest on the estimated value of
investment in land and trees, the total cost without owner supervision is obtained.
These S sets of figures are shown in total and per-acre for each of the 2 seasons,
and the per-box figures are shown for the first season.
Returns from fruit are shown on the 3 bases for the first season only.
This means that figures for net returns to owner and returns above operating costs
are shown only for the first season reported. Net returns to owner are obtained by
subtracting the total cost without owner supervision from the returns from fruit.
This is the amount remaining after operating costs and 6 percent interest on the
grove investment have been included as costs. Some desire a net figure without in-
cluding interest on the grove investment as a cost, hence, the figure, returns above

The tree record according to the latest information of this office for
the most recent season indicated is shown in order for the grower to check for
accuracy and inform this office of any errors or changes in tree count.
Some general information is included such as the name of the cooperator,
name of the grove, whether or not the grove is irrigated, number of trees per acre,
percent of trees that are grapefruit, and the pounds of nitrogen applied in the form
of fertilizer for each box of fruit harvested.
Recently added to the report have been rankings of groves averaging over
10 years of age on 7 items as follows: boxes harvested, fruit returns, operating
costs, returns above operating costs, spray and dust materials, and fertilizer costs,
all on a per-acre basis, and nitrogen added per box of fruit harvested. In each of
S these items the groves are arrayed in order of the amount or size of the figure
under consideration. In three of these items--fruit harvested per acre, fruit
returns per acre, and returns above operating costs-the highest figure is taken as
rank number one. The lowest figure is rank number one for each of the remaining 4
items. Each ranking figure indicates the standing of the grove among all groves
averaging over 10 years of age of these records and affords the grower another basis
of comparison. In many instances rankings are better comparisons than averages for
the group. If a grove ranks 215, there are 214 other groves with a better ranking
in the item under consideration.
Composite rankings are made by adding all ranking figures of each grove
to form a composite number for that grove. The grove having the lowest total figure
is the grove with the highest total ranking. A check was made to determine how
total rankings for the 1947-4S season compared with the returns above operating
costs. These results are shown in Table 1. Of the 25 percent of groves that sea-
son, 54 in number, with the highest returns above operating costs per acre, 83 per-
cent were highest also in total rank. Similarly, 80 percent of the lowest 54 groves
in returns above operating costs were also groves with the lowest total rank.

It is contemplated that the rank in all items taken together will be shown
on individual reports made in the future. Other items of ranking that may be in-
cluded are on-tree price of all fruit and operating cost per box.
