PEPPER VARIETY TRIAL G rUL



Winter Pepper Trial. 391 1963 I. '-' .

To evaluate 20 varieties and/or lines o sCeet, 'blocky peppers
grown in the 1962-63 season.

Considering both yield and quality, Yolo Wonder L produced the
highest yield of quality pods in the cold injured trial harvested
in April, 1963. Idabelle and Early Calwonder produced the second
best yield of quality pods.

PLANTING: Each plot, 0.00065 acre, consisted of a single row, 10 feet long. Two
pepper rows were sown on each 68 inch bed. Pepper seeds were sown with a
Planet Jr. seeder set at hole 16 and 3/4 depth (fifth notch) of depth
regulator. Plants were thinned to a 9-inch spacing.

research and industry. Results herein neither constitute nor imply recom-
mendation of any particular pepper variety.

2. % I

FERTILIZER: A total of 330 pounds each of N and K20 and 60 pounds of P205 per acre
were applied. A total of 600 pounds of 5-10-5-0.2 Bg20 fertilizer was banded
on both sides of the seed row at planting time. In addition to the complete
fertilizer, 3 sidedressings of 10-0-10 fertilizer was applied biweekly at the
rate of 300 pounds per acre per application. A total of 3 sidedressings were
applied monthly in December, January, and February at the rate of 600 pounds
per acre per application.

PESTICIDE TREATMENTS: Pesticides were applied throughout the growing season.
Copper and chlordane sprays were applied at weekly intervals. Diazinon
sprays were applied 3 days after the copper sprays.

EXPERIMENTAL DESIGN: Randomized block design with four replications.

LOG: Sown: 10/24/62.
Harvests: First: 4/4/63. Last of 3: 4/22.

DISCUSSION AND RESULTS: The 1962-63 winter growing season was good except for the
frost of December 11, 1962. The average daily maximum temperatures for
November, December, January, February, March, and April were 77, 74, 76,
75, 82, and 84 degrees F., respectively.
The minimum temperatures varied during the growing season. The average
daily minimum temperatures from November through April were 57, 51, 56,
55, 62, and 61 degrees F. December was the coldest month with several
frosts. On December 11, the official temperature at the 5 foot level
dropped to 30 degrees F., but 28 degrees was recorded at a vegetable
station at the 1 foot level, in the variety trial. The official tempera-
ture dropped to 32, 34, and 33 degrees on December 13, 14, and 15,
respectively.

Rainfall was variable. Only two rains of over 0.75 inch intensity fell
during the growing season- 0.88 inch on February 4 and 2.97 inches on
February 13. Because of the dry weather at times, plants in replication
I suffered from lack of water.

The December ll.freeze killed some of the growing tips of young plants.
As a result, some plants produced a multiple shoot. Probably some of
the variation in yield resulted from scattered frost injury and dry
soil in the higher replications.

Three harvests of pepper pods were made. The first harvest occurred 162
days after sowing of seeds, and the last harvest was made 18 days after
the first harvest. The total (including culls), U. S. fancy, and market-
able (U. S. fancy + U. S. #1) pod weights were recorded for each harvest.
Duncan's Multiple Range Test was used to compare mean yields.

Varieties did not result in any significant U. S. fancy pod yield differ-
ences for the first harvest at the 5% level of statistical significance.
Wide variations were found among replications.








Varieties did not result in any significant total (including culls) pod
yield differences for 3 harvests at the 5% level of statistical signifi-
cance. Table 1 contains the yield of pepper pods for total (including
culls), fancy, and marketable (fancy + U. S. #1) from 3 harvests.

Varieties did result in significant U. S. fancy pod yield differences
for 3 harvests at the 5% level of statistical significance.

Yolo Wonder L (3) outyielded Early Calwonder (7), Rio Wonder (16),
Resistant Florida Giant (12), Florida Giant (9), Yolo Wonder Improved
B(1), Yolo 43 (1), Wonder Giant (2), B 314 (20), and California Wonder
(14). Early Calwonder (15) outproduced Florida Giant (9), Yolo Wonder
Improved B (11), Yolo 43 (1), Wonder Giant(2), B 314 (20), and California
Wonder (14). In addition, Idabelle (18) outyielded Yolo 43 (1), Wonder
Giant (2), B 314 (20), and California Wonder (14).

Varieties did not result in any significant marketable (fancy + U. S. #l)
pepper pod yield differences at the 5% level of statistical significance.
Quality ratings, based largely on appearance of pods, were made at each
harvest. Yolo Wonder L (3) and Rio Wonder (13) produced the best quality
pods in the trial. Keystone Resistant Giant (8) and Pacific Bell (17),
produced the second best quality pods, and Idabelle and XP 300(19)
produced the third best quality pods.

Considering both yield and quality, Yolo Wonder L produced the highest
yield of quality pods in the 1963 pepper trial, harvested in April from
disease-free plants. Idabelle (18) produced the second best peppers,
and Early Calwonder (15) produced the third best pods.
