Dlantina and harvest dates.
The experiment was conducted at A. Duda and Sons farm, field 9,
unit L. Seedbeds were sown November 13, plants set in the field February 25
and harvested May 8, 1964.
Field plot technique.
Randomized block design with four replicationswas used. Plots were
40 feet long with plants spaced 7 inches in rows 2 feet apart. In both
the replicated and observational celery trials, single row plots were
employed. The harvest row was 30 feet long with a plot area of 60 square feet.

HORTICULTURAL TRIALS WITH CELERY VARIETIES
V. L. Guzman OCT 13 1964
Two types of trials were conducted: l-observa:t'i freplicated.
The first test eliminated those lines or varieties Wii iffr no possi-
bility for the fresh market. Varieties which exhibited best possibilities
in past observational trials are compared in replicated designs in the
Character of the weather during the trials.
This season was characterized by temperatures below normal from
November to March. The first frost of the season was November 15th
followed by freezing or near freezing temperatures on December 2nd,
5th, 10th, llth, 25th, 26th,January 2nd, 3rd, 15th and February 9th, 12th,
21st, 24th. Except for a few instances, temperatures were not below the
300 F. mark, but the season in general was one of prolonged cold and
cloudiness. The celery plants therefore were subjected to lowvtemperatures
in the seedbeds and a large number of bolters or seeders was expected as
a consequence of temperatures below 500 F. Rainfall was scattered with
a few heavy rains between long dry spells. The celery crop, however, made
good growth and reached maturity slightly ahead of the estimated time.
This was probably due to favorable growing conditions during March and

The experimental area was cropped to corn and cabbage during the
past season. Soil analysis indicated a; mean pH value of 6.4 with 29.5
pounds of phosphorus and 295 pounds of potassium per acre. The grower-
cooperator applied sufficient fertilizer for the nutrient needs of the
Weed, disease and insect control
Post-transplanting application ov Vegadex at the rate of 5 pounds per
acre controlled weeds satisfactorily. One month later after the first
mechanical cultivation, 4 Ibs./A of a mixture of Randox and Vegadex applied
half and half gave additional control of weeds. However, due to heavy
growth of volunteer sesbania, several mechanical cultivations and two hand-
weedings in the row were necessary to keep the field clean. For the control
of diseases, Nabam plus zinc sulfate or Dyrene were the standard fungicides
with tribasic copper alternating every two to three weeks. Insect control
with Toxaphene, Phosdrin and Dibrom was effective.

Tables 1 and 2 present performance data of the celery varieties in the
..observational.and replicated trials respectively. The check varieties were
52-70-2-13 and 52-70 regular (nos. 1 and 2). Regular 52-70 significantly
produced better total yields than 52-70-2-13 and the other varieties ex-
cept 8-655A. Similar trends were found for trimmed weight and crates per
acre. Significant differences were found in petiole width, number of
petioles and in number of pithy petioles among varieties. Variety 52-
70-2-13 had outstanding width of petiole, fewer pithy petioles, but fewer
number of petioles and more featherleaf. Lines 5-391-190 and 6-391-19A
produced the lowest weight of trimmed and untrimmed weight and greater
amount of cracked stem, although differences of the latter were not signi-
ficant. Line 655A was intermediate between regular 52-70 and 52-70-2-13
in total yields before trimming. This line however, produced a considerably
larger number of cracked stems although differences were not statistically
significant. Lines 52-70LS, 391-190 and 19A and 655A had darker green
petioles. These last two lines had the appearance of summer Pascal type
cJleries. Line 52-70LS had good color and appearance, except for excessive
growth of the eaxllary bud at the base of the petioles. Considering all
variables, no.variety tested had the appearance of the. checks; they were
inferior in at least one variable. In the observational trials Greenlight
and its selections showed good productivity, but appearance of the stalks
was inferior to 52-70-2-13. The Greenlight selections had long slender pe-
tioles with spreading growth tending to be less compact and more open than
the 52-70 selections. There were no material differences in color between the
sales stock and.those classified as nonchlorotic. Although the new lines were
not superior to the checks, the following deserve further trials: 52-70 from
Abbott and Cobb, E.E.S. 212B, and all the new selections of 52-70 from Harris

Total untrimmed fresh weight. Total weight in pounds of all the celery stalks
before cleaning, stripping and topping.
Trimmed fresh weight. Weight in pounds of all celery stalks after cleaning,
stripping and topping to 16 inches.
Crates per acre, estimated yield. Plants were graded into plant size, from
l1 to 6-8 dozen per crate as commercially done. From the number obtained of
each grade, crates per acre were calculated.
Length of petiole from base to first node. Petiole length was obtained by
measuring in inches the distance from the base to the first node of the petiole
of 10 plants selected at random per replication and variety.
Width of petiole midway between base and first node. These data were taken in
centimeters. The same number and petioles used for measurement of length of
petiole were employed for width studies.
Number of retioles. All petioles except those forming the heart cone of the
plant. The value is the mean of 10 plants per variety and replication.
Cracked stem. The number of cracked stems of 10 plants per variety and repli-
cation was recorded. The main symptom of this disorder is transverse outward
peeling of the epidermis and adjoining tissue, which becomes brown. It appears
mostly at the node of the petiole. Varietal differences to cracking are very
Pithiness at the base of the petiole. Obtained by counting in each replication
and variety the number of pithy petioles in 10 selected plants at random. Pithi-
ness is the breakdown of thin walled cells in the parenchyma which leaves hollow
places in the petiole..
Number of feather leaf. Obtained by counting the number of leaves showing dis-
coloration of the leaf blade of 10 plants selected at random per variety and
Pencil stripe or celery "rust". Obtained by examining 10 selected plants at
random per plot and variety and recording the number of affected petioles.
Pencil stripe appears as longitudinal brown striping of the petioles. Gener-
ally it affects the heart petioles first. The lesions are usually small and
sometimes rusty looking, therefore the name given by some growers of "rust".
In most cases the very small stripings are transversal to the stalk and the
union of many of them gives the longitudinal appearance. It is a very serious
disorder, ruining the marketability of the produce when severe. In this test
pencil stripe was found erratically in very few stalks.
Appearance: One person's opinion of the general appearance of the stalks
after trimming. P = poor; F = fair and G = good. The signs plus (+) or
minus (-) after P, F or G indicate slightly superior or inferior rating
Height of plants-Mean of 10 plants measured in inches from soil surface to
the highest leaf.
