This publication discusses growing and harvesting head lettuce, the most important salad vegetable grown in the United States. Per-capita consumption exceeds 25 pounds annually. In North Carolina, the crop can be grown as both a spring and fall crop in eastern North Carolina and even during midsummer in western North Carolina at elevations higher than 3,000 feet.
Carrots can be produced almost year-round in parts of North Carolina. Both fresh market and processing types hold potential. This publication will assist commercial farmers with growing and harvesting carrots.
This factsheet covers celery, which could be a very profitable crop in North Carolina. A harvest period in late June or early July, and one in October, would fill market voids when other major celery producing areas are not harvesting. Celery, however, is not an easy crop to grow. Although it is a cool season crop, exposure of juvenile plants to temperatures below 40 to 50ºF for more than 5 to 10 days can cause premature bolting, making the crop unsalable. Special attention must be given to maintaining a steady water supply and providing the proper amount of nutrients to allow for constant growth.
Cauliflower is a cool season crop, closely related to broccoli, cabbage, kale, turnips, and mustard. It is more exacting in its climatic requirements than most other crops in this family. It grows best in a comparatively cool temperature with a moist atmosphere. With proper management cauliflower can be grown in North Carolina as either a spring or fall crop, although the fall crop will generally produce better quality.
Okra is grown throughout North Carolina in home gardens and for commercial markets. It is a warm season crop that belongs to the cotton (Mallow) family and should not be planted until the soil has thoroughly warmed in the spring. Okra is referred to as 'Gumbo' in some areas.
Asparagus has been grown for many years. The Ancient Greeks and Romans relished this crop. It originated in Asia Minor and is a member of the lily family. California, Michigan, and Washington are the major producing states, but there is some commercial production in many of the northern and western states. Warm regions such as Northern Mexico and Southern California also grow it. This publication covers recent research that has shown that asparagus can be grown at a profit in North Carolina.
Much success in growing tomatoes can be attributed to use of a few proven techniques. Choosing a variety that has proven to be a true performer should be at the top of every gardener's list. Better Boy, Whopper, Celebrity, and Mountain Pride are among some of the best selections. Better Boy, Celebrity, and Whopper are VFN, which means they carry resistance to verticillium wilt, fusarium wilt, and root-knot nematodes. It is best to experiment with several varieties in order to find the ideal tomato for your taste buds.
When onions are harvested in the green or immature stage they are called "green bunch onions." These onions are sold in bunches tied with a rubber band. This is a popular crop for home and market gardeners in the fall, winter and early spring. Acreages are usually small because of the amount of hand labor required for planting and preparation for market.
Asparagus has been considered a garden delicacy since Roman times. Any home gardener can grow and enjoy this spring vegetable. Asparagus is a perennial. If you plant and manage properly it will produce for 15 years or more. Since this crop will occupy the land for many years you should select and prepare the asparagus bed carefully -- location, soil type, soil fertility, size and age of crowns and correct planting are important.
Increasingly, fresh produce growers, packers and sellers are being asked to prepare and maintain written Recall Programs. Elements for FDA "Product Recalls" are in 21CFR7.40, et. seq. Adopting that statutory approach to create Fresh Produce Recall Programs may help the Fresh Produce Industry convert public concern into strategic aid.
Maintaining good sanitation throughout production and handling of strawberries, raspberries, blackberries, and blueberries is important. It is vital that growers and, in turn, their employees understand just how critical any food poisoning outbreak could be to their livelihoods. Pathogens harmful to humans can be transmitted by direct contact (infected employees or animals) or through contaminated water or soil. Once a fruit is infected, pathogens are difficult or impossible to remove. Only thorough cooking (or other similar treatment, such as pasteurization) will reliably neutralize pathogens. Fruits that are field-packed without washing have a higher likelihood of reaching consumers with field contamination. This document focuses on how to best reduce contamination.
Sprouts from mung bean (Phaseolus aureus) have been used for food since ancient times. These sprouts have a nutrient value similar to asparagus and mushrooms, which contain high quantities of Vitamin A. Sprouts can be canned or frozen in addition to eating them fresh. Mung bean seeds can be purchased from mail-order commercial seed companies and health food chain stores. (Caution: Regardless of the source, do not use seeds that have been treated with a fungicide. Treated seeds are not edible and can be recognized by the coating of pink or green dust on the seed coat.)
