The symbol OG indicates a product is listed by the Organic Materials Review Institute (OMRI) as approved for use in organic production. Please see Table 25 and Fungicides and Bactericides Alphabetical Listing by Trade Name for more information on products with the same active ingredients. In many cases, there are other products available with the same active ingredient. NOTE: For the disease control products listed below, one product trade name and formulation is provided for each active ingredient (common name) as an example of rates, preharvest interval (PHI), restricted entry interval (REI), and special instructions. Topped beets can be stored for 3-6 months or more at 33-36º F and 98% relative humidity. Once harvested, chard can be kept for 1-2 weeks at 32☏ and 95-98% relative humidity.īeet: Bunched beets can be kept for 10-14 days at 32☏ and 98% relative humidity. Chard is frost resistant and can be harvested well after the first killing frost. Many successive harvests can be made from one planting. Swiss chard: Chard does not bolt or go to seed as readily as spinach and, therefore, is a good summer substitute. For most beet varieties (except monogerm varieties) each seed ball contains up to 6 seeds, so thinning is required. Both beets and chard may be transplanted for an earlier spring crop. ![]() apart aiming at a density of 15-30 plants per foot. PLANT NUTRIENT RECOMMENDATION ACCORDING TO SOIL TEST RESULTS FOR BEET AND SWISS CHARD Make sure that the next crop in the rotation schedule is not sensitive to boron residue. To prevent deficiency, apply 2 lb B per acre (10 lb Solubor, 20 lb borax) with the broadcast fertilizer application. This is accompanied by internal breakdown, canker, or dry rot of the root. Less nitrogen fertilizer will be needed if legume sod was plowed down or if manure was applied (see Table 1 and Table 7).īeets are subject to boron deficiency young leaves fail to develop normally, turn black and die. High levels of nitrogen in relation to phosphorus and potassium will result in heavy leaf production with poor root development. In alkaline soils, the chance of boron and manganese deficiency is increased. Types and Varieties Beet and Chard VarietiesĬhioggia Guardsmark - OP, striped interiorĪpply lime according to soil test to maintain soil pH at 6.5-6.8. Organic matter should be well decomposed to avoid scab problems with beets. High organic content in the soil is desirable and will help maintain an adequate moisture supply. Beets grow best in deep, friable, well-drained, sandy loams to silt loams. alternating light and dark rings and lower sugar content. The higher temperatures of summer can cause "zoning" in beets, e.g. ![]() The best quality is obtained when beets are grown under conditions of good sunlight and cool temperatures (50-65☏). Chard is raised for its large leaves and stems, and beets are raised both for greens and roots. ![]() Both are cool-season crops that can tolerate frosts and light freezes. cicla) are members of the Chenopodiaceae family, along with lambquarters. crassa) and Swiss chard ( Beta vulgaris var. ![]()
