HAND HARVEST TOMATO VARIETY TRIAL RESULTS FOR FALL 1981

T. K. Howe, J. W. Scott and W. E. Waters1


A replicated fall tomato variety trial was conducted at the Agricultural
Research and Education Center, Bradenton, Florida to evaluate the performance
of various commercial cultivars and IFAS breeding lines.

Materials & Methods

All entries, (Table 1) were germinated in wooden flats containing SAF-T-
BLAST(R) (Mineral Aggregates,.Inc.), a processed product of spent coal. Trans-
planted seedlings were grown approximately 7 weeks in Speedling(R) trays (1" x 1"
cells) containing vermiculite and transplant peat-lite mix (2:1). Transplants
were set in the field on September 11, 1981. Some resetting was necessary and
final resetting occurred 16 days after initial transplanting. The planting was
on raised beds of Myakka fine sand (1) treated with Dowfume R) MC-33 at 350 lbs/A.
Fertilization consisted of 1,250 lbs/A of 18-0-25-2, distributed in 2 bands 18
inches apart, and 100 lbs/A each of 18-0-25-2, Uramite(R) (33% N), and superphos-
phate (0-20-0) containing 80 lbs/ton micronutrients (503 oxide) broadcast in the
center of the bed. The 34" wide beds were mulched with black plastic and then
painted white to reduce the surface temperature of the mulch. Plants were set
24" apart in single rows in the middle of each bed and staked. Beds were spaced
on 4.5 foot centers with irrigation ditches every 7 rows. Four replicates of 10
plants per entry were arranged in a randomized complete block design. Standard
pesticides were applied for insect and disease control. Additionally, foliar sprays
of NutrileafR) (20-20-20) were applied on Nov. 11 and Dec. 8, 1981 at 5 lb/100
gallons to supplement fertilizer under the plastic.

Fruits were harvested on December 7, 15, and 21, 1981. Tomatoes were sized
by machine, counted, weighed and graded into cull or marketable fruit. Defects
of the cultivars were noted during the grading procedure.

Results and Discussion

Results are in Tables 1, 2, 3, 4, and 5. Data for all three harvests are
in Table 1 and each harvest is handled separately in Tables 2, 3, and 4.

The data show that 'Hybrid 58' had the best overall performance. It was at
the top of the range in marketable and total yields, had a reasonably low percentage
of culls, produced significantly heavier fruit, and yielded significantly more
large fruit than twelve of the other thirteen cultivars (Table 1). Other strong
entries were 'A1990' F5 which had good yield but a tendency toward smaller fruit;

'Duke' which had good yield and fruit size but produced a high percentage of culls;
'Burgis' which had good yield with a tendency toward smaller fruit; 'Florida 1B'
which was impressive in the production of large fruit, but had a fairly high cull
percentage; and, 'Freedom' which also produced large fruit but had one of the
greatest cull percentages.

Earliness (harvest #1) was greatest for 'Hybrid 58' which had significantly
greater marketable and large fruit yields than all entries except 'Florida 1B'
(Table 2). Other cultivars with good early yields were 'Florida 1B', 'Burgis',
'Duke', 'Freedom' and 'Corda'. All had a tendency to produce larger fruit,
especially 'Florida 1B'.

In general, fruit size decreased as the season progressed (Tables 2, 3, and 4).
The percentage of large fruit also declined, especially by the third harvest due
to freezing temperatures reached on December 20, and 21, shorter day lengths, and
depletion of fertilizer late in the season. These factors could have diminished
yields in general, which tended to be low. The fact that the last picking was
premature, could have negatively biased yields for later cultivars such as 'Hayslip'.
There was a tendency for yields to increase as the season advanced, even though
yields favored smaller fruit.

Table 5 contains information on the types of characteristics noted for culled
fruit. Cracking, blossom end scars, and blotchy ripening were the most predomi-
nant defects among all entries.
