Cabbage grows well in the cool climate of North Dakota, but cabbage production is limited due to market uncertainty and lack of information on available hybrids. We evaluated the suitability of 9 cabbage hybrids for both the fresh and slaw markets. These 9 hybrids were evaluated using two planting methods: direct seeded and bare-root transplants.
MATERIALS AND METHODS
Soil: |
Embden sandy loam and Hecla sandy loam; pH=6.9; 2.9% organic matter; soil-P and soil-K were very high; soil-S was low. |
Previous crops: |
2003 - sweetcorn; 2002 - pepper, winter squash and pumpkin; 2001 - field corn and soybean. |
Seedbed preparation: |
Disked on April 13. Multiweeded (field cultivated) three times -- once on April 23 to incorporate the fertilizer and twice on April 28 to incorporate the herbicide. |
Planting: |
Direct seeded cabbage and a barley cover crop (0.45 bu/acre) on May 4 with a Monosem precision planter. Cabbage seeds were placed ½ to ¾ inches deep into a flat, fine seedbed and were spaced 6 inches apart in 21-inch rows. Plants were later thinned to about 12 inches apart (about 25,000 plants/acre). Seeds . A row of barley was planted between and parallel to the cabbage rows. Transplants were started in the greenhouse on April 19 and transplanted on May 20 with a 12-inch in-row spacing. |
Plots: |
Main plots were 34 ft long by one row (21 inches) wide. Each main plot was divided into two 17-ft long sections. The study had 4 reps. |
Fertilizer: |
On April 15, broadcast 20 lbs N/acre and 24 lbs S/acre as 20-0-0-24. Applied 50 lbs N/acre on April 23, 60 lbs N/acre on July 6 and 40 lbs N/acre on July 23 as 28-0-0. |
Irrigation: |
Surface drip irrigation as needed |
Pest Control: |
Weeds were controlled using Treflan (1 pt/acre applied preplant incorporated on April 28), Fusilade + NIS (12 oz/acre + 0.5% v/v on June 9 and June 25, which also killed the barley cover crop) and by hand weeding. Sprayed Sevin (1 qt/acre on June 24) to control flea beetle. Asana (6 oz/acre on June 14), DiPel (1 lb/acre on June 29, July 9, July 15, July 21, July 29 and August 4) and Warrior (3.8 oz/acre on August 11) controlled cabbage looper and cabbage worm. |
Harvest: |
One section of each main plot was hand harvested when heads were firm and of marketable size (early harvest for fresh market). The other section was harvested about two weeks later (late harvest for slaw market). Cabbage head characteristics were measured on representative cabbage heads selected at each harvest from each plot. |
Direct-seeded cabbage: For the fresh market, Trigger and Bronco looked the best while Trigger and Artost had the greatest yields. For the slaw market, Trigger, Almanac and Artost looked the best, and Almanac, Artost and Fresco had the best yield.
Transplanted cabbage: For the fresh market, Bronco, Artost and Trigger looked the best, and Trigger, Fresco and Cambria had the highest yields. For the slaw market, Artost, Gazebo and Almanac looked the best and Almanac and Matsumo had the highest yields. Transplanted cabbage generally was earlier maturing and better quality than direct seeded cabbage.
