CABBAGE HYBRID PERFORMANCE TRIAL, 1996

Richard G Greenland and Leonard Besemann

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. Data were collected to determine suitability of the hybrids for both the fresh and slaw markets.

Results summary

MATERIALS AND METHODS

Soil: Hecla sandy loam and Embden sandy loam; pH=6.9; 2.8% organic matter; soil-P was high; soil-K was medium; soil-S was very low.

Previous crops: 1995 - tomato and pepper; 1994 - pumpkin; 1993 - field corn.

Seedbed preparation: Disked on April 22. Multiweeded (field cultivated) three times on April 22, once to incorporate fertilizer and twice to incorporate herbicide.

Planting: Direct seeded on April 23 with a Stanhay vegetable planter. Seeds were spaced about 7 inches apart in 17-inch rows. Plants were later thinned to 15 inches apart (about 26,000 plants/acre). Seeds were placed about ½ to 3/4 inches deep into a flat, fine seedbed.

Plots: Main plots were 34 ft long by one row (17 inches) wide. Each main plot was divided into 2, 17 ft long sections. The study had 4 reps.

Fertilizer: On April 17, broadcast 14 lbs N/acre and 70 lbs P₂O₅/acre as 10-50-0, 16 lbs N/acre and 19 lbs S/acre as 21-0-0-24, and 94 lbs K₂0/acre as 0-0-60. Sprayed 35 lbs N/acre as 28-0-0 on April 22. Side dressed with 110 lbs N/acre as urea on July 8.

Irrigation: Surface drip irrigation as needed.

Pest Control: Weeds were controlled using Treflan and Devrinol (1 pt and 2 lb/acre applied preplant incorporated on April 22), Dacthal (8 lbs/acre on April 24), Lentagran (2 lbs/acre on June 7), and by hand weeding. Sevin (1.5 pts/acre on May 29) controlled flea beetles. Cabbage was sprayed with Javelin (1 lb/acre on July 15), with Asana (8 oz/acre on July 10, July 26, and Aug 2), and with DiPel (1 lb/acre on Aug 9) to control 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). The other section was harvested about two weeks later (late harvest). Cabbage head characteristics were measured on representative cabbage heads selected at each harvest from each plot.

RESULTS

Yields were higher this year than in 1995. Some of the better fresh market hybrids were Columbia, Atlantis, Blue Pak, Fresco, Ramada and Gideon. Columbia, Fresco, Atlantis, Royal Vantage, Ramada and Grand Prize were the best for slaw cabbage. Super Red 80 (fresh market) and Regal Red (slaw market) were the best red hybrids. See Tables 9 to 12.

²Harvest spread is the number of days between first head ready to harvest until last head in plot ready to harvest.

³Head shape: 1 is very flat; 2 is flat; 3 is round; 4 is tall; 5 is very tall.

⁴Values in the same column followed by the same letter are not significantly different at the 0.05 level (no letters in column = no significant differences between values in that column).

⁵The hybrid 'Hinova' was not included in the statistical analysis because of large variability between plots caused by late and uneven maturity.
