Peach Results at Quincy, Florida in 1960

H. W. Young
Assistant Horticulturist


Yields

The 1060 peach yield records at Quincy, Florida are summarized in Table 1.
The yield was taken on tree ripe fruit. When comparing yield weights of any two
varieties, the age of tree must be considered. The are of tree listed in the
table is the number of full growing years in the orchard.

Fruit characteristics

Certain fruit measurements are presented in Table 2. The red overcolor is
important because the buyer usually prefers a large portion of the fruit to be
red. By comparing the length and diameter the general shape of the fruit can be
visualized.

Cold hours

Peach varieties require different amounts of cold by February 15 to break
their dormancy and to bloom normally. The numbers of hours of temperature at or
below 450 F in the winter of 1959-60 were 650 prior to Feb. 15; 772 before Feb.
2A; and 018 by March 15. Varieties such as Sunhigh (750 hours) bloomed over
rather a long period of time and had slow and irregular foliage break which
indicated that their chilling requirements were not fully met by Feb. 15.

Thinning

The fruit on the trees were thinned by hand to remove excessive set,
Generally the fruit left on the tree were spaced at least 4 inches apart.

Spring freeze .- S

Below freezing temperatures the latter part of F-r'er."'r. ili-d mr--tof
the fruit set at that time. Therefore early flowering 1.ri_.i~s, it lw
chilling requirements) produced few or no fruit. '

Fertilization
'' *' ''
One pound of 8-8-8 per year of age of the tree was apri3'c 'r^3 around
the trees in the feeding root area. In July one-quarter por,_n :1.rr w-v nitrate
per year of age of the tree was applied in the same manner.

Diseases, insects, and spray program

Rust was the most prevalent disease but was not a real problem until
late in the season. Stink bugs were present, however, damage was negligible.
Wormy fruit were not found. Brown rot was not a problem until July.

Two applications of wettable sulphur were made during the blossoming
period. Thereafter eight sprays of 2 pounds parathion (15%) and 6 pounds
wettable sulfur (80% /) per 100 gallons of water were applied at approximately
10 day intervals. Immediately preceding the harvest, wettable sulphur alone
was applied.

On July 15, August 15 and September 15 trunk sprays of 8 pounds of
DDT (50% w.p.) per 100 gallons of water were applied to assist in control of
the peach tree borer.

Observations and Recommendations

These yield trials are being continued and additional varieties are
being added each year. In addition, selections from breeding material will
be added to the orchard for evaluation. On the basis of information to date
only Mvygold can be recommended for limited planting to satisfy the early
shipping market. In those years when there is sufficient cold, Sunhigh and
Hiland might be suggested for the grower to supply a local market. Earligold
has appeared promising for the early shipping market, however, further testing
is needed. Flordaqueen may (because of its low cold requirement and fair-
sized fruit) have a place for the supplier of a local market where earliness
is not essential. Further suggestions concerning some of the other varieties
must be reserved until additional testing has been completed.
