CUCUMBER VARIETY TRIAL, FALL 1988 JUN 21 1989

T. K. Howe and W. E. Waters1 University of Florida


Preliminary Florida vegetable statistics for 1987-88 indicate that the
value of cucumbers was $54.78 million (3). The production of 5.7 million
55 lb-bushels came from 14,850 acres. The value of cucumbers was only
exceeded by tomatoes, peppers, strawberries, sweet corn and lettuce.
Cucumbers are grown primarily in west-central Florida, southwest Florida
and southeast Everglades area. In 1986-87, 27% of the production came
from west-central Florida (2). Commercial production in west-central
Florida largely occurs on raised, mulched beds with seepage irrigation,
whereas in other areas these conditions may not apply. A variety trial at
the GCREC was conducted in the fall of 1988 to screen fresh market
(slicing-type) cucumbers for use in west-central Florida.

MATERIALS AND METHODS

Raised beds of EauGallie fine sand were formed on August 12, 1988. The
33-inch wide beds were spaced on 5 ft centers with seepage irrigation
ditches spaced every 6 beds. An acre was equivalent to 8712 linear feet
of bed. Fertilizer included 18-0-25-2 (N-P205-K20-Mg0) at 125 lb/1000
linear feet of bed (LFB) placed in 2 grooves 10 inches to each side of bed
center; and a full bed-width, incorporated application of superphosphate
(0-20-0 with 80 lbs per ton minor elements as F503) at 75 lb/1000 LFB.
Beds were fumigated with Vorlex at 4.0 gal/1000 LFB and covered with white
polyethylene film.

Seed of all entries (Table 1) were sown on August 4, 1988 into Todd9
planter flats (Speedling, Inc. 1.5 x 1.5 x 2.5-inch cells, model 150)
containing vermiculite:Canadian peat (1:1,v:v) amended with
superphosphate, dolomite and micronutrients.

Transplants were set in the field on August 25, 1988 in single rows down
the bed center with 12 inches between plants. Plants were immediately
drenched with 20-20-20 fertilizer at 5 lb/100 gal water. Four
replications of 12 plants per cultivar were arranged in a randomized
complete block design.

The crop was scouted for pest problems throughout the season. Major
insect pests included assorted lepidopterous larvae and sweet potato
whitefly. Populations were managed with esfenvalerate, methomyl, oxamyl
and Bacillus thuringiensis. Preventative applications of the fungicides
chlorothalonil and mancozeb 80 were utilized throughout the season to
control mildew, anthracnose, target spot and gummy stem blight. These
diseases ,id not appear during the trial. Prevailing weather conditions
for August, September and October 1988 appear in Table 2.

Cucumber fruit were harvested three times a week beginning on September 23
and concluding on October 14 (See Table 3 for all harvest dates). Fruit
were sorted into U.S. Fancy, No. 1, and No. 2 and unmarketable categories
according to the U.S. Standards for grades of cucumbers (1). Once sorted,
fruit was counted and weighed.

RESULTS AND DISCUSSION

Yield are expressed in bu/1000 LFB and bu/A in Table 1. Greatest U.S.
Fancy yield was produced by 15 of the 24 cultivars and all exceeded 60
bu/1000 LFB. The range of U.S. Fancy yield was 49 bu/1000 LFB for 'Comet
A' to 78 bu/1000 LFB for 'Maximore 100'. Greatest U.S. No. 1 yield was
produced by 16 of the 24 cultivars and all were greater than 12 bu/1000
LFB. The greatest yield of U.S. No. 2 fruit was produced by 'PS 184' at
22 bu/1000 LFB. Eight cultivars produced at least 75% of their respective
total seasonal yield as U.S. Fancy fruit (Table 3).

Cull production ranged from 4.2% for 'Poinsett 76' to 26.1% for 'Slice
Max'. Nine cultivars produced less than 11% cull fruit, 'Poinsett 76',
'Poinsett 76S', 'Dasher II', 'PS 184', 'Sprint 440 II', 'Flora-Cuke',
'Early Triumph', 'Supersett' and 'Slice Nice'.

Average fruit weight for the U.S. Fancy grade of fruit ranged from 8.6 oz
for 'Poinsett 76S' to 9.9 oz for 'Monarch'. Eighteen cultivars were equal
to or exceeded 9.0 oz for U.S. Fancy fruit. Average fruit weight for the
U.S. No. 1 grade of fruit ranged from 7.0 oz for 'Dasher II' to 9.0 oz for
'Slice King'. Only fruit weight of equal to or less than 7.6 oz was
significantly less than the 9.0 oz fruit produced by 'Slice King'.
Average fruit weight for the U.S. No. 2 grade ranged from 5.5 oz for
'Poinsett 76' to 7.6 oz for 'Comet A II'.

To indicate the degree of earliness and the concentration of fruit
maturity of the entries, the percentage of marketable yield by harvest
date appears in Table 4. 'Slice King' and 'Slice Max' each produced 10%
of their total marketable yield on September 23. 'Poinsett 76', 'Early
Triumph' and 'Poinsett 76S' produced no fruit on September 23. By
September 26, all entries were harvested at between 15 to 29% of their
total marketable yield.

Total seasonal yields from this trial were from 1.6 to 2.6 times greater
than the state's commercial average (3). The use of transplants, the high
number of harvests and a mulched-culture production system were likely
contributing factors to the high yields. Variety trials typically focus
on potential yields and relative differences since harvests are not market










driven. High total seasonal yields, high proportion of U.S. Fancy grade
fruit and low cull production serve as a guide in selection of cultivars
for use in this area.
