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, jumbo and dicing types of carrots.
MATERIALS AND METHODS
Soil: |
Maddock sandy loam, Hecla sandy loam and Embden sandy loam; pH=7.1; 2.5% organic matter; soil-P was very high, soil-K was medium, and soil-S was low. |
Previous crop: |
2003 - potato; 2002 - cabbage, carrot, edible bean, field corn, onion, potato, soybean, sugar beet, sweetcorn and wheat; 2001 - field corn. |
Seedbed Preparation: |
Disked on April 2 and May 26. Multiweeded (field cultivated) three times on May 27 – once to level the seed bed and twice to incorporate fertilizer and herbicide. |
Planting: |
Direct seeded raw carrot seeds on May 28 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, 500,000 seeds/acre for jumbo, 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 (two rows plus the wheel track). 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 May 27 and 60 lbs N/acre on July 15 as 28-0-0. |
Irrigation: |
Surface drip irrigation as needed. |
Pest control: |
Weeds were controlled using Treflan preplant incorporated (1.5 pt/acre on May 27), Lorox (1 lb/acre on May 28 and 1.5 lbs/acre on June 30), Fusilade + NIS (12 oz/acre + 0.5% v/v on June 19, which also killed the barley cover crop), and by hand weeding. Sprayed Baythroid (2.8 oz/acre on August 2, August 12 and August 19) to control leafhopper. |
Harvest: |
The baby, cut and peel, and cello carrots were harvested three times: baby on July 19, July 26 and August 2; cut and peel on August 2, August 9 and August 18-19; and cello on August 11, August 18, and August 25. The jumbo and dicing carrots were harvested once: jumbo on October 8 or October 11; and dicing on October 12. 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, Intercepter and Inverness carrots were longest, Intercepter carrots were thinnest, while Niagra had the highest yields. But many Niagra carrots were too fat for cut and peel carrots. Niagra had the highest total yields of the cello type carrots. Bradford, Cupar and Niagra were the highest yielding jumbo types. Niagra, Cupra and Carson had the highest yield of the dicing types of carrots. But these high yielding carrots had the palest dry color. Niagra and Cupar had the lowest and Kingdom had the highest percent dry matter.
