In North Dakota, carrots grow very well. Carrots have greater commercial production potential than any other vegetable. We tested true baby, cut and peel, cello, and processing types of carrots.
MATERIALS AND METHODS
Soil: |
Embden loam and Gardena loam; pH=7.3; 2.1% organic matter; soil-P and soil-K were very high; soil-S was medium. |
Previous crop: |
2001 - potato; 2000 - edible bean, pepper, soybean, sugar beet and wheat; 1999 - field corn. |
Seedbed Preparation: |
Coulter chiseled twice, 15 inches deep, on April 18. Multiweeded (field cultivated) three times; once on May 16 to incorporate fertilizer and smooth seed bed and twice on May 20 to incorporate herbicide. |
Planting: |
Direct seeded raw carrot seeds on May 22 with a Monosem precision planter. Carrot planting pattern was 3 lines per row (2 inches between lines in the row) with rows on 18-inch centers. Planting rate was about 500,000 seeds/acre for processing, 800,000 seeds/acre for cello, 1.2 million seeds/acre for cut and peel, and 1.4 million seeds/acre for baby carrots. A row of barley cover crop (0.45 bu/acre) was planted between and parallel to the carrot rows. |
Plots: |
Plots were 17 ft long by three feet wide and were arranged in a randomized complete block design with 4 reps. |
Fertilizer: |
On April 18, broadcast 18 lbs N/acre and 20 lbs S/acre as 21-0-0-24. Applied 50 lbs N/acre as urea on July 3. |
Irrigation: |
Overhead sprinkler irrigation as needed. |
Pest control: |
Weeds were controlled using Treflan (1.5 pt/acre on May 20), Poast + Dash (1.5 pt + 1 pt/acre on June 17), Lorox (1 lb/acre on May 22 and 2 lbs/acre on June 25), and by hand weeding. Sprayed Asana (8 oz/acre on July 15, July 30, and Aug 13) and Sevin (1 qt/acre on Aug 27) to control leafhopper. |
Harvest: |
The baby carrots were harvested twice (July 24 and 29). The cut and peel were harvested twice (July 29 and August 7). The cello carrots were harvested thrice (Aug 8, Aug 14, and Aug 21). The processing carrots were harvested once (October 9). The harvest area was two rows wide by three feet long for all carrots. |
Adelaide was the best baby carrot tested. For cut and peel carrots, Interceptor carrots were longer and thinner, while Tempo and Infinity had higher yields. Bolero and Bradford had the highest yields of the cello type carrots, with Bolero having good quality and Bradford having poor quality. Florida and Bangor were the highest yielding of the processing types, but below average quality. Vac-30 (Siroco), Infinity, Tempo, Idaho and Bolero had the best quality in both cello and processing type carrots. Stands and yields were generally below average this year.
