PEPPER HYBRID PERFORMANCE TRIAL
Richard Greenland, Leonard Besemann and Heidi Eslinger
Table 48. Quantity and yield of peppers
Table 49. Cumulative yields of marketable peppers
Peppers generally grow surprisingly well in southern North Dakota, although late in the season some hot peppers lose their heat if the weather is too cool. In cool years, yields and quality may be reduced.
MATERIALS AND METHODS
Soil: |
Embden loam and Maddock sandy loam; pH=6.6; 2.4% organic matter; soil-P was very high; soil-K was high; soil-S was medium. |
Previous crop: |
2002 - soybean; 2001 - sweetcorn; 2000 - carrot. |
Seedbed preparation: |
Disked on May 19. Multiweeded (field cultivated) twice on May 21 to smooth the seedbed and to incorporate herbicide. |
Planting: |
Peppers were seeded in the greenhouse on April 8. Plants were hand transplanted on May 28. Planting pattern was paired rows (12 inches between rows) on 4-ft centers. In-row spacing was 18 inches within a single row, which put a plant every 9 inches for the paired rows. As it was planted, each plant received 1 cup of fertilizer solution (1% solution of 10-34-0). |
Plots: |
Plots were 17 ft long by 4 ft (one paired row) wide. There were 4 reps. |
Fertilizer: |
On April 9, broadcast 11 lbs N/acre and 52 lbs P205 as 11-52-0, 30 lbs K2O as 0-0-60 and 18 lbs N/acre and 20 lbs S/acre as 21-0-0-24. Applied 30 lbs N/acre as 32-0-0 on May 13. Applied 20 lbs N/acre as 28-0-0 on June 30. Side dressed 50 lbs N/acre as urea on June 16. |
Irrigation: |
Overhead sprinkler irrigation as needed. |
Pest control: |
Weeds were controlled by Roundup + NIS (16oz/acre + 1 qt/50 gal on May 14), Treflan (1 pt/acre on May 21), and by hand weeding. |
Harvest: |
Hand harvested 9 times from July 23 to September 24. |
Paladin was again the best pepper. All of the peppers tested produced very good yields and quality.

Note: Jalapeño Grande was not included in statistical analysis of number of peppers/acre. It is a different type of pepper and had many more peppers/acre, which causes problems in statistical analysis. It was included in the pepper yield analyses.

2Fruit shape - 1 is blocky; 2 is elongated; 3 is tapered; 4 is jalapeño; 5 is Hungarian wax.
3Outside color - 1 to 3 is light to dark yellow; 4 is yellow green; 5 to 7 is light to dark green.
4Overall score - Overall score includes appearance but not yield. The higher the number the better the pepper.
Note: Jalapeño Grande was not included in the statistical analysis for values in this table because it was a different type of pepper and had values widely different than the bell peppers, which causes problems in statistical analyses.
