Carrots parsnips

Carrot family beet family Grow carrots, parsnips, celery, beets, spinach, and chard on this plot On poorer ground, add compost to the soil, except where carrots and parsnips are to be sown. Sow winter rye or buckwheat as a green manure over winter. 

Details of preparation and storage conditions for crops that last well through the winter are given here (seepanel, left). Some other crops can also be stored for shorter periods for example, carrots, parsnips, beets, rutabagas, and celeriac keep well if packed in moist sand or fine leaf mold in shallow trays or boxes.

Minshall and Helson (7) of the Dominion Department of Agriculture at Ottawa, Canada, have studied the physiological action of petroleum naphtha on carrots, parsnips, and several weeds including mustard. They used infrared absorption apparatus, and by means of readings taken at 10-second intervals following oil application, determined that photosynthesis ceased abruptly for all plants studied. With parsnips, photosynthesis was resumed within 30 minutes after application it was one third of norm at the end of 3 hours, and at the end of 48 hours reached approximately the original rate before treatment. Parsnips did not wilt following treatment. The common mustard plant had a...

Deep plowing (8-12 inches with a moldboard plow), if properly done over a period of a few years, will gradually increase the depth of the topsoil. For most field crops, as stated above, this may have little effect but for certain special crops, such as vegetables, there is some evidence that this is beneficial on some soils. Crops, such as carrots, parsnips, and sweet potatoes, that prefer a loose soil, may grow better in a deep topsoil, well-supphed with humus, than in a shallow one. The importance of such deep soils in gardening is still uncertain because most deep plowing experiments have been conducted with field crops, and often in soils where root penetration was not an important factor Needless to say, there is a marked difference in the response of different kinds of plants to the soil environment.

Citric and malic acids are also the predominant acids in vegetables and their relative abundance varies with the vegetable. For example, in potato, sweet potato, leguminous seeds, many leafy vegetables, tomato, and beetroot, citric acid is the main acid. However, malic acid dominates in cucurbits, lettuce, artichoke, broccoli, cauliflower, okra, onion, celery, carrot, parsnip, turnip, and green beans [12] (Tables 10.3 and 10.4).

MYRISTICIN In moderate amounts in dill, carrot, celery, fennel, mace and nutmeg (no more than 10% tops). Makes up about 40% of the oil of parsnip and can reach up to 50-60% of the oil of parsley leaves and seeds. Give nutmeg a rest folks It just don t have it when compared to parsley and parsnip.

Parsnips, for example, belong to the same family—the Apiaceae—as carrots, and are also a favourite of the carrot rust fly.

Small, shiny black flies lay eggs in small clusters near host plants, starting in late spring. The larvae are creamy-white, up to Vz in (1 cm) long. Pupae, and sometimes larvae, overwinter in soil and roots of carrot and parsnip. There are two or three generations per year, the first causing most damage. 

Susceptible plants Primarily a severe pest of carrots. Also attacks celery, chervil, parsley, and parsnip.

Plants that can cause photodermatitis include carrots, celery, parsnip, dill, fennel, caraway, parsley, lovage, anise, and chervil among the Apiaceae (Umbelliferae, or carrot family), figs (Moraceae), and citrus fruits (grapefruit, lemon, lime.

Refined oils of the Stoddard solvent type, safe and effective for handling carrot crops, were developed after a relatively short period of research. Their use spread to celery, parsnips, parsley, and anise. Foresters, finding that conifer seedlings were tolerant to the refined oils, sprayed forest tree nurseries. Research proved that a somewhat less toxic oil could be used on flax and onions. The use of refined selective spray oils found a definite place in the agriculture of our country. 

Experiments were conducted at Cornell in an attempt to learn more about the effects of temperature on oil toxicity. Small carrot and parsnip plants were placed at four temperature levels 40 to 50 , 50 to 60 , 60 to 70 , and 70 to 80 F. After 2 weeks at these temperatures, one sixth of the plants in each group were sprayed at the rate of 80 gallons per acre with a Stoddard solvent (Varsol No. 2) which contained an additional 4% diethylbenzene. One week after the first treatment a second lot of plants was sprayed in the same manner. Ten replications of carrots and five replications of parsnips were used. Harvests were made 2 weel after the treatments. 

Temperature had a marked influence on the growth of the plants. There was very little visible difference, however, in the effect of the spray on the plants at the various temperatures. As shown in Table II, the per cent reduction in fresh weight of carrots caused by the sprays was less at the 60 to 70 temperature than at any of the others. Similar results were obtained for parsnips. 

Following the lead provided in 1942 and thereafter by truck gardeners in carrot (S) and parsnip (ff) fields, investigations were started in nursery weed control, involving use of some of the more highly refined petroleum products known as mineral spirits or petroleum spirits. Their common industrial uses are as cleaning naphthas, paint thinners, and solvents. Among trade names of products successfully used in weed control in forest nurseries are Stoddard solvent, Sovasol No. 5, Varsol, Stanisol, Shell solvent, and Sohio weed killer.

Cadmium is present at low concentrations in most foods, with those that are consumed in larger quantities making the largest contribution to the population dietary exposure. Although the concentrations of cadmium in food in the UK are generally low, some foods of minor dietary importance such as shellfish or kidney often contain levels in excess of 0.5 mg/kg. Plant-based foods rarely contain more than 0.2 mg/kg on a fresh weight basis, although some root crops such as carrots and parsnip, and some leafy crops, such as spinach and lettuce, tend to contain more cadmium than other plant foods. This is also true of cereals, which indicates that plants tend to take up cadmium from the soil, unlike lead.

The majority of swallowtail butterflies of the genus Papilio (family Papilionidae) exclusively utilize plants of the family Rutaceae as hosts, with a few species exploiting limited plant species of the families Apiaceae or Lauraceae. The North American black swallowtail butterfly, Papilio polyxenes, a specialist on members of carrot family (Apiaceae), has already been shown to lay eggs in response to a mixture of two chemotactile stimulants, luteolin 7-0-(6"-0-malonyl)-/3-D-glucoside and trawr-chlorogenic acid, identified from one of its major host plants, Daucus carota (wild carrot). Further study revealed that the oviposition response by the butterfly to another host plant, Pastinaca sativa (wild parsnip), was evoked by a combination of tyramine (1), trans-chlorogenic acid, and a neutral fraction from the plant.4...
