INDIVIDUAL GROVE REPORTS


By
Zach Savage
Associate Agricultural Economist
Florida Agricultural Experiment Station


From the citrus costs and returns study now in progress through the coopera-
tion 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 reports
with which to compare his own individual report, which is made from each grove record.

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
P 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
a period of time in which the fruit was marketed. Such a procedure results in a
*ord kept for a grove for the period of September 1, 1948 through August 31, 1949
-ing tabulated as yield and returns for the season of 1948-49 and costs for the
jason of 1949-50. This method results in the latest season tabulated being without
fieldd and returns.

The individual report includes costs and returns for the most recent season
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 outlined in the form on pages 2 and 3. 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 average 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 8 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
operating costs.

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 informa-
tion is included such as the name of the cooperator, name of the grove, soil type,
*whether or not the grove is irrigated, number of trees per acre, and percent of trees
by kinds of citrus.

{- The 1947-48 individual reports included the rankings of individual groves
in seven items for groves over 10 years of age. This has been expanded in the 1948-
49 reports to include 13 items and combinations of items. The ranking of a grove on
a particular item indicates the standing of that grove in relation to the group of
groves included in the study. For example, if the individual grove ranks 15 in boxes
harvested per acre, there were 14 groves with higher yields and 185 with lower yields
Also, rankings for seven items are included on the 1949-50 costs. Your reactions
regarding these rankings are solicited.

Individual grove reports for the 1947-48 season included the amount of
nitrogen per box added to the grove that season for groves over 10 years of age. The
report for the current season includes the amount of 10 fertilizer elements added as
fertilizer and spray during the season on the bases of per acre, per box, and ratio
ST of the 9 other elements to nitrogen. Figures for the 10 elements are also presented
on the three bases as "suggested for average grove." These "suggested" figures are
only approximations to serve only for comparative purposes as representing an
"average" grove. Different groves have different requirements as to kinds and
amounts of fertilizer elements needed. The needs of most individual groves vary from
these average figures. Requirements or needs of the individual grove vary with a
number of factors, among which are reserves in the soil, type of soil, kind of citrus,
age of trees, and condition of trees. Fertilizing practices such as applying ddomite
during alternate seasons would materially affect these figures by showing ample to
excess additions of calcium when added and no additions during alternate seasons.
The average number of boxes of fruit harvested in 194S-49 was 342 boxes per acre and
"suggested" figures for an average grove of this yield are shown. Likewise, such
figures are shown for an average grove with the same yield as the individual grove of
the particular report. Your comments concerning this type of fertilizer information
would be appreciated very much.

Composite rankings were made by adding all ranking figures of the indi-
vidual grove to form a composite number for that grove. The grove having the lowest
total figure was the grove with the highest total ranking. The grove with the next
lowest total ranked second highest. The remaining groves were ranked in inverse
order of size of total ranking figures.
