PEPPER VARIETY TRIAL RESULTS FALL 1983

Paul H. Everett and Karen A. Armbresterl

A replicated field trial was conducted at the Agricultural Research and
Education Center, Immokalee, Florida during the fall season (Sept. Dec. 1983)
to evaluate the performance of 15 pepper cultivars and/or breeding lines.
Table 1 shows the list of entries and corresponding seed sources used in this
trial.

EXPERT I \RARY

All entries were seeded in Tod R platWe 1B3lih 50 (1. inch cell size) on
August 10, 1983, and were transplant d to field plots on Se ember 15, 1983. Field
plots were arranged in a randomized omnlee hb k P h three replications
of each entry. Each plot consisted -fr2 1 row with 8 inches
between plants and 12 inches between rows on raised plant beds spaced 6 feet apart.
Plant beds were irrigated with an open ditch seep system with lateral ditches
spaced 41.5 feet apart. There were 5 plant beds between lateral ditches. Reported
yields are based on 7260 linear bed feet (LBF). On August 29, all plots were
fertilized with 5-8-8-1.2 + micronutrients at 6.9 lb/100 LBF and 19-0-30 at 13.8
lb/100 LBF. The 5-8-8-1.2 fertilizer was spread in a 30 inch band on a pre-bed
then bedded over to a depth of 4 inches. The 19-0-30 fertilizer was banded on
each shoulder of the finished bed 9 inches from the plant rows. The finished bed
was then fumigated with VorlexR at 21 ounces/100 LBF and then mulched with white
plastic film. Total amount of fertilizer N and K20 were 3.0 and 4.7 pounds per
100 LBF,respectively. Preplant soil tests indicated high levels of available
phosphorus, therefore only a maintenance application of 40 pounds of P205 per acre
was included in the fertilizer program. On the basis of 7,260 LBF per acre the
N-P205-K20 fertilizer was 215-40-340 pounds, respectively. Fruit were harvested
on November 21, December 8, December 20, and December 27, 1983. The last harvest
was approximately 36 hours after a freeze which occurred during the night of
December 25 and morning of December 26. At each harvest fruit were counted,
weighed and graded into marketable or cull fruit. The general weather conditions
during this trial are shown in Table 2.

RESULTS

Table 3 shows the marketable yields for each of the 15 entries. First harvest
yields ranged from a high of 1247 bushels/7260 LBF for 'Bell Tower', which was
significantly higher in yield than 8 of the other 14 entries, to a low of 689

bushels/7260 LBF for FMX-724, which was significantly lower in yield than 10
of the other 14 entries. Yields from all entries were' statistically equal at
the second, third and forth harvests. The second harvest yields ranged from
a high of 808 bushels/7260 LBF for 'Cadice' to a low of 455 bushels/7260 LBF
for 'Early Calwonder'. 'Gator Belle' ranked highest at the third and forth
harvests with 539 and 408 bushels/7260 LBF, respectively.' The highest total
marketable yield in this trial was from 'Cadice' (2693 bu/7260 LBF) but this
was not statistically different from 'Gator Belle' (2594 bu/7260 LBF), 'Shamrock'
(2546 bu/7260 LBF), P7118 (2352 bu/7260 LBF) or PSR 1102 (2352 bu/7260 LBF).

In the first harvest P7118 ranked highest in average fruit weight at 5.6
ounces/fruit (Table 4) but was significantly equal to PSR 3475 (5.5 oz/fr),
P130 (5.4 oz/fr), PSR 1102 (5.0 oz/fr), and 'Bell Tower' (4.9 oz/fr). In the
second harvest PSR 3475 (6.6 oz/fr) and P7118 (6.1 oz/fr) ranked significantly
higher in average fruit weight than the remaining'13 and 10 entries, respectively.
In the third harvest PSR 3475 (4.8 oz/fr) retained its rank as having the highest
average fruit weight but was significantly equal in size to 6 of the remaining
14 entries. There were no significant differences in fruit size at the forth
harvest.

The percent fruit at first harvest with 3 or 4 lobes is shown in Table 4.
Entry P130 had the highest percentage of fruit with 4 lobes.

Table 5 shows the wall thickness and length to diameter ratio of first
harvest fruit from the 15 entries in this trial.
