PEPPER HYBRID PERFORMANCE TRIAL, 2001

Richard Greenland, Leonard Besemann and Delores Anderson


Results summary

Table 28. Quantity and yield of peppers

Table 29. Quality of peppers

Table 30. 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:

Hecla sandy loam, Embden sandy loam and Maddock Sandy Loam; pH=6.8; 2.0% organic matter; soil-P was high; soil-K was very high; soil-S was very low.

Previous crop:

2000 - field corn; 1999 - soybean; 1998 - pumpkin and winter squash.

Seedbed

preparation:

Disked on April 20. Multiweeded (field cultivated) four times; once on May 8 to smooth the field, once lightly on May 9 to incorporated fertilizer and twice on May 27 to incorporate herbicide.

Planting:

Peppers were seeded in the greenhouse on April 8. Plants were hand transplanted on May 27. Planting pattern was paired rows (12 inches between them) 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 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 19, broadcast 10 lbs N/acre and 50 lbs P2O5/acre as 10-50-0 and 18 lbs N/acre and 20 lbs S/acre as 21-0-0-24. Sprayed 50 lbs of N/acre as 28-0-0 on May 9. Side dressed 50 lbs N/acre as urea on July 11.

Irrigation:

Underground drip irrigation as needed.

Pest control:

Weeds were controlled by Treflan (1 pt/acre on May 27), rototilling, and by hand weeding.

Harvest:

Harvested hot peppers 10 times and sweet peppers 8 times from July 26 to Sept 27.

RESULTS


          Giant Jalapeno, the only hot pepper, had the highest yield. Vivaldi had the highest yield of the sweet peppers. Paladin and Legionnaire were the best looking and also had high yields.
