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, processing and dicing types of carrots.
MATERIALS AND METHODS
Soil: |
Maddock sandy loam; pH=6.9; 2.1% organic matter; soil-P and soil-K were very high; soil-S was low. |
Previous crop: |
2002 - potato; 2001 - cabbage, carrot, edible bean, field corn, onion, potato, soybean, sugar beet, sweetcorn and wheat; 2000 - field corn. |
Seedbed Preparation: |
Chisel plowed and disked once on April 24. Multiweeded (field cultivated) once on May 8 to level seed bed and twice on May 26 to incorporate herbicide. |
Planting: |
Direct seeded raw carrot seeds on May 21 and May 23 with a Monosem precision planter. Carrot planting pattern was 2 lines per row (2.5 inches between lines in a row) for the processing and dicing carrots and 3 lines per row (2 inches between lines in the row) for all other carrots with rows on 18-inch centers. Planting rate was about 330,000 seeds/acre for dicing, about 500,000 seeds/acre for processing, 800,000 seeds/acre for cello, 1.2 million seeds/acre for cut and peel, and 1.86 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 9, broadcast 11 lbs N/acre and 52 lbs P205 as 11-52-0, 30 lbs K2O as 0-0-60 and 18 lbs N/acre and 20 lbs S/acre as 21-0-0-24. Applied 40 lbs N/acre as 32-0-0 on May 13. Fertigated 50 lbs N/acre as 28-0-0 on June 26. Applied 30 lbs N/acre as urea on July 16. |
Irrigation: |
Overhead sprinkler irrigation as needed. |
Pest control: |
Weeds were controlled using Treflan (1.5 pt/acre on May 16), Poast + Dash (1.5 pt + 1 pt/acre on June 17, which also killed the barley cover crop), Lorox (1 lb/acre on May 23 and 1.5 lbs/acre on June 30), and by hand weeding. Sprayed Asana (8 oz/acre on July 17, July 30, and August 8, August 22) to control leafhopper. |
Harvest: |
The baby carrots were harvested once (July 21). The cut and peel were harvested twice (July 30 and August 6). The cello carrots were harvested three times (August 4, August 11, and August 22). The processing carrots were harvested once (October 13). The dicing carrots were harvested once (October 15). The harvest area was two rows wide by three feet long for all carrots. |
Adelaide was the only baby carrot tested. For cut and peel carrots, SugarSnax54 and Intercepter carrots were longer, Intercepter carrots were thinner, while Tempo had higher yields. Bolero had the highest total yields and quality of the cello type carrots, with Tempo having highest yield of US # 1carrots. Florida, Carson and Bersky were the highest yielding and best quality of the processing types. Florida, Bersky and Bergen had the highest yield and quality of the dicing types of carrots.
