Field 1 (D. G. A. Kelbert)

TOMATO VARIETY TRIALS

Purpose:

To compare several advanced Gulf Coast Station lines which are considered
potential new varieties, with Manalucie and Indian River for yield, qual-
ity, and size of fruits as well as other horticultural characters.

History: Seed sown January 11. Plants transplanted to the field February 29.
Rows are 54 inches apart, plant spacing is 16 inches. Plants are pruned
to 2 stems. To provide needed cover, pruning was discontinued on upper
third of plants.

Varieties:

1. Manalucie standard for vine ripe harvest
2. Indian River standard. for early-setting habit
3. STEP 305 of. interest for resistance to tobacco mosaic.
4. STEP 314 tests during past two years have clearly demonstrated
that it possesses the range of adaptation feature of
Rutgers and can be depended upon for size, smoothness,
and quality of fruits. Decision about the release of
this stock has been deferred until Dec. 1.
5. STEP 344 of interest for desirable combination of size and smooth-
ness of fruits, but of questionable value in Florida be-
cause it lacks best degrees of resistance to graywall
and tolerance of heat and cold.
6. STEP 346 has shown that it possesses the refinements that give a
very high proportion of No. 1 fruits, but, in Florida
they are too often failing to develop sufficient size.
7. STEP 359 a younger sister of STEP 314, possibly superior to it
in color, roundness, and crack-resistance of fruits.
8. STEP 360 a new entry. Truly outstanding in the 1959 fall crop
for early set of large, smooth fruits; but it may not
be adapted in spring and fruits may lack firm, slow-
ripening quality desired for vine-ripe harvest.
9. STEP 361 a new entry. Chosen from 1959 fall crop as best all-a-
round prospect that might be suitable for both ground
and staked culture.
10. 363-5-1-Bk CAStW a new entry. This line is the result of a cross be-
tween STEP 344 and a close relative of STEP 314. In the
1959 fall crop it showed, until cold weather struck on
Nov. 29, a truly impressive yielding potential, but it
failed to make size and quality of fruits thereafter.
Observations suggest, however, that it has the desired
tolerance for high temperatures, so further study is
arranged.
11. 363-12-1-Bk CAStW a new entry. Another selection of the "363" family
with high yielding potential, but it lacks resistance to
graywall.
12. 249-1 FPI-Bk CAStW a new entry. Chosen from fall crop for high mar-
ketable yield. Was best for resistance to growth cracks
and weather blemishes, but fruits not best for firmness
and wall thickness.













Recommended Varieties:
Staked Culture
Mature-green harvest
Homestead 24, with modified pruning
Indian River
Vine-ripe harvest
Manalucie
Indian River, for fall and winter harvest

Ground Culture
Homestead 24
Indian River
Grothen's Globe, if on new land

For limited planting, new variety Marion has multiple resistance to
disease and has performed well in G.C.S. trials. Seed probably
available for 1961 crop.

Field 4 (D. G. A. Kelbert)

TOMATOES WITH DETERMINATE TYPE VINES AND
MODIFIED CALIFORNIA TYPE TRELLISING


Purpose:


To test the determinate type tomatoes for yield, quality and fruit size.
To test the efficiency of this type low cost trellis in holding fruit
above the ground to afford protection from ground rots.

Planting data:

There are 26 entries in the test. The first 11 are Fl hybrids and Nos.
27-28 are F2 hybrids of the types that are popular in some sections of
California. The balance are semi-determinate types that have their ori-
gin at the G.C.S. and they carry the same disease resistance as the
G.C.S. indeterminate types. The check variety is No. 26, Homestead 24.
Seed were planted on January 14, and plants were transplanted to the
field March 1. Rows are 54 inches apart and plant spacing is 30 inches.
Cultural data is the same for this crop as for other tomatoes except
that they have not been pruned.

POLE BEAN BREEDING

Purpose:

Pole Bean Breeding Stocks under comparison with standard varieties
F-M 191, McCaslan, Florigreen and Blue Lake. Those lines under family
number 967 and shortened designations, D, E, F, G, and H are from the
cross between McCaslan and Florigreen. These are located on the east
end of block and are all stringy large-podded lines. There has not
yet been sufficient development of rust to allow the sorting of these
selections for rust reaction. The only important disease showing on
the crop is yellow bean mosaic.



Field 9 (J. M. Walter)

TOMATO BREEDING

Purpose:

Tomato Selections in Lining-out Comparisons for observations and further
selections. Crop is too late to allow proper evaluation this season -
in fact it may not be possible to obtain the needed seed from these lines
unless weather is favorable for another month.

RECOMMENDED PROCEDURE
By one or a combination of the following
operations keep populations of soil pests
as low as possible between cash crops:
(1) clean cultivation, (2) crop rotation,
(3) alternate flooding and drying.


2. Recognize the pests which must be con-
trolled, i.e., fungi, nematodes, weeds.

Do consult your County Agent, Plant Board or

3. Choose the proper fumigant for the job. Do base choice on pests to be controlled, cost
to crop value, method of application and equipi
available. Do consider the desirability of con
as many pests as possible in one operation: i.

INSECTICIDAL AND PHYTOTOXILOGICAL TESTS

Purpose:

The effect of granular Thimet as a soil insecticide and other insecti-
cides on growth and yield of 191 pole beans.

Treatments:

East End Yield
1. Check 27.4
2. Check 29.6
3. Thimet 1 1/2# actual per acre in-the-row 11.7
4. Thimet 3# actual per acre in-the-row 3.1

West End Yield
1. Guthion 1# 48.0
2. Thiodan 1# 55.5
3. Sevin SP 2# 50.7
4. Check 46.2

Results:

Records are incomplete. Three pickings have been made as of Friday,
May 6. The reduction in yield is due to damage from rabbits or
Thimet, or a combination of the two. Maneb has been used weekly un-
til April 25 when two sprays were applied weekly, using sulfur at 16
pounds per hundred the first part of the week and maneb at the last
part of the week. This schedule is still in effect.



Field 16 (E. G, Kelsheimer)

INSECTICIDES

Purpose:

Commencing March 11 these plots of tomatoes received a weekly spray
of SP33, a pyrethrum compound. No fruit record have.been taken.

Tomatoes

Purpose:

Manalucie plants were reset so often that the plots are being used for
insecticide residue studies. Last major reset was February 3. South
plots received a soil treatment of Thimet granules. The first treat-
ment was February 23 on rows 5 and 6. Row 6 received an additional
treatment on March 28.





Field 17 (C. M. Geraldson)

N SOURCE AND MINOR ELEMENTS

Purpose:

To study the effect of five inorganic nitrogen sources in combination
with two minor element sources on yields and quality of tomatoes, sweet
corn, pole beans, squash and cucumbers.

Treatments:

Sodium nitrate + potassium sulfate
16 Check
17* + Minors (Manganese, zinc, boron, iron and molybdenum

Ammonium nitrate + potassium sulfate
26 Check
27 + Minors

Ammonium sulfate + potassium sulfate
36 Check
37 + Minors

Calcium nitrate + potassium sulfate
46 Check
47 + Minors

Calcium nitrate + potassium nitrate
56 Check
57 + Minors

*Minors were supplied as foliar sprays every 7 to 10 days.

History Crop Variety Planted
Tomatoes Manalucie 12/28 (Set 2/26)
Sweet corn 60-Pac 2/25
Squash Yellow Crookneck 2/25
Pole beans Florigreen 2/29
Cucumbers Ashley 2/25

Fertilizer Triple Super 250#/A. before planting (S block only)
250#/A. 10-0-14 weekly (total to date 2500#).

Results:

When the initial soil pH was 6.0 or higher, best yields and quality of
such crops as pole beans, sweet corn and cucumbers were associated with
the ammonium nitrate and ammonium sulfate fertilized plots compared to
those receiving sodium nitrate. When calcium nitrate or calcium plus
potassium nitrate were used as source materials, yields and quality
were sometimes equivalent to those plots producing the best and at
other times were rated as inferior to the ammonium nitrate or ammonium
sulfate fertilized plots, but generally superior to the sodium nitrate
fertilized plots. When the initial soil pH was 5.0 or lower, poorer
yields and quality of tomatoes were associated with the all-ammonium
nitrogen source.
