PEPPER HYBRID PERFORMANCE TRIAL, 2000
Richard Greenland, Leonard Besemann, and Heidi Slinger
Table 35. Quantity and yield of peppers
Table 37. 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: | Maddock sandy loam; pH=7.4; 1.9% organic matter; soil-P, soil-K, and soil-S were very high. |
Previous crop: | 1999 - cabbage; 1998 - field corn; 1997 - onion. |
Seedbed preparation: | Disked on 29 October 1999. Multiweeded (field cultivated) once on April 5. Deep tillage on May 23. Multiweeded (field cultivated) twice on June 6 to incorporate herbicide. |
Planting: | Peppers were seeded in the greenhouse on April 3. Plants were hand transplanted to the field on June 7. 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. Each plant received 1 pint of fertilizer solution (1 gal 10-34-0 in 100 gal of water) at planting. |
Plots: | Plots were 17 ft long by 4 ft (one paired row) wide. There were 4 reps. |
Fertilizer: | On April 4, broadcast 18 lbs N/acre and 20 lbs S/acre as 21-0-0-24. Fertigated 35 lbs N/acre as 28-0-0 on June 27 and on July 14. |
Irrigation: | Overhead sprinkler irrigation as needed. |
Pest control: | Weeds were controlled by Treflan (1 pt/acre on June 6), rototilling between rows, and hand weeding as needed throughout the season. No disease or insect control was required. |
Harvest: | Harvested hot peppers 8 times and sweet peppers 7 times from Aug 2 to Sept 21. |
Paladin had the highest yields, biggest fruit, and best quality of the bell peppers. Summer Heat 5000 was the best Jalapeño. ACX 400 did well for a Hungarian Wax type. Yields of peppers, especially hot peppers, were lower this year than most other years.
