D. William2INTRODUCTIONGrowing quality vegetables requires knowledge and skills of both crop pr oduction and business practices. To harvest high yields of quality pr oduce you must plan each production step and complete each cultural practice on time. Growers must know about liming, fer tilizing, irrigating, controlling pests, harvesting, grading and marketing each vegetable crop. Decisions about timing each cultural practice, which variety to grow, where to market the produce, and figuring production costs, require planning and can make the difference between a profit and loss. To grow vegetables commercially, market gardeners must study and invest both time and money in their business. Each vegetable crop requires certain cultural practices for proper growth and production. Some vegetables require special practices such as mulching or staking to produce highest yields and quality. Certain types of specialized equipment may be needed to grow some vegetables efficiently. Finding or developing markets will require both time and skill in selling and dealing with people. Accurate records of costs and sales are essential to improve your production and business decisions. Before you decide to grow vegetables commercially, study the following general information and plan your production and marketing options carefully. Then, after making the preliminary decisions, you can read and study the specific production guides for each vegetable crop and other publications listed in Appendix F.FARM AND MARKET LOCATIONThe location of your farm will help determine the type and success of a market garden enterprise. For example, roadside markets should be located near large c ities and along busy highways. "U-pick" or "Pick-your-own" operations should be easy to find and located within 10 to 30 miles of larger cities. In rural areas, vegetables may be sold at the farm, peddled door-to-door, or offered for sale at community markets. Market gardeners located farther away from consumers usually transport their produce to community markets or to local wholesale outlets. For more information about locating roadside or "U-pick" markets, read the publications listed in the Marketing section of Appendix F. When buying farmland for vegetable production, choose land that can be drained efficiently, yet irrigated during possible droughts. Avoid trying to produce vegetables on deep, coarse sandy soils or in low, swampy areas with inadequate drainage facilities. Learn more about the special management practices needed to produce high yields of quality vegetables on each type of soil f ound in Florida by reading the publications listed in the Soils and Fertilizer section of Appendix F.

Also, specialty crops such as Laboratory or County Extension Agent.Chinese vegetables or "organically" grown vegetables Interpret your soil test results carefully. Start by comparing the soil pH number of your soil with a range of 6.0 to 6.5 that is best for most vegetables in Florida. Then compare the amount of calcium (CaO) and magnesium (MgO) available in your soil with a range of 400 to 800 lbs. calcium and 100 to 200 lbs. magnesium needed per acre to grow quality vegetables. Usually, a ratio of 4 to 5 parts calcium to 1 part magnesium will provide a balance of these two plant nutrients in the soil. Buy dolomite limestone if your soil test results show that magnesium is low or the ratio of calcium and magnesium content in your soil is high. Otherwise, buy Hi-cal limestone when calcium is low. Apply these limestone materials evenly and mix into the top 6 inches of soil 2 or 3 months before planting. For most Florida soils requiring lime, apply about 1 ton of ground limestone per acre to raise the soil pH one unit. In our example, 1.5 tons ground limestone would be required per acre to raise the soil pH from 5.0 to 6.5.CHOOSING THE RIGHT VEGETABLES TO GROW Labor requir ements Planning and careful study are necessary before selecting vegetables to grow commercially. Consider these factors before making your final decision: or southern peas. Sometimes these assembly markets sometimes can be marketed within your community.Vegetable production and manag ement factors In Florida, vegetables are grown during specific seasons on several different soil types using a variety of crop management practices. Although cultural practices and production costs vary somewhat among regions of Florida, most vegetables can be grouped into general categories depending on over-all management levels and required labor (Appendix A). For example, low management crops require relatively lower amounts of production inputs such as fertilizer, pesticides, irrigation and staking or mulching than other vegetable crops. Medium management crops require moderate input levels. In contrast, high management crops often require highest input levels and precise management of the crop to produce quality vegetables at a profit. Often, the use of full-bed plastic mulch will increase both yields and quality of high management crops. For more information about specific crop management practices for each crop, read the extension publications and production guides listed in Appendix F. In Florida, small-scale vegetable production by market gardeners often requires hand picking and comparatively simple grading and packing facilities. Because considerable labor is required to produce, harvest and handle most vegetables, consider the labor requirements of each crop before making your final choice of which crop to plant (Appendix A). Verify that you will

PAGE 3

Growin g Qualit y Ve g etables in Florida Pa g e 3April 1999have adequate labor during peak periods such as transplanting, trellising or harvesting your vegetables. In contrast, the mechanized production, harvesting and handling of potatoes, sweet corn, carrots, radishes, celery, and other crops destined for larger markets requires more capital investment. These crops normally are produced by large-scale growers where production and handling efficiencies are increased with mechanization in both the field and packinghouse operations. Both largeand small-scale vegetable growers must plan carefully and manage their labor efficiently. Longterm success in marketing perishable vegetables often depends on a regular and dependable supply of produce for either retail customers or wholesale buyers. Careful planning of your production practices and sk illful labor management are essential for success.VEGETABLE YIELD ESTIMATES IN FLO RIDAPlanning for efficient production of vegetables or other commodities requires an estimate of at least average yields for Florida or for your production region. Statewide averages or estimates of acceptable yield levels for vegetables grown in Florida under various crop management levels and on several types of soil are listed in Appendix B. Excellent or high yield estimates are also listed because most vegetable growers strive to increase production efficiencies and profits by producing high yields. By figuring production costs at each yield level, growers or market gardeners can calculate break-even or per unit costs. In most situations, per unit costs for the higher yield levels will be less and profits will be greater. Remember, however, these yields are statewide averages or estimates. All yield data depends on many factors including your crop production and business management skills, soil types, location within Florida, season, and weather. This information is useful in planning your vegetable production busine ss, but should be modified as you study and gain experience in your particular region of the state. Your County Extension Agent, farm supply dealer and other local vegetable growers may be able to assist you in modifying these data to improve your, planning and decision-making process. Careful planning and study can help you maximize profits and provide a dependable supply of quality pr oduce to your customers.EQUIPMENT AND CULTURAL PRACTICESStandard equipment for most market gardeners includes at least a small tractor with a water-cooled, 15 or more horsepower engine, a standard 540 RPM power takeoff (PTO), a high clearance of 20 inches or more, and a 3-point hitch. Generally, this type tractor provides dependable service and often is a good investment. Standard implements may include a disc or rototiller, fertilizer spreader and side-dressing equipment, planter, cultivation attachments, nematicide applicator and pesticide sprayer. Optional equipment for your tractor might include a bed press, plastic mulch applicator, herbicide sprayer, rotary mower, or potato digger. Other essential equipment includes an irrigation unit and possibly a small washing unit for cleaning certain vegetables before packing.Field preparation and timing After selecting a field, begin soil preparation by plowing under all plant trash and debris 3 to 4 months before your planned planting date. Early plowing and discing will allow time for the weeds and plant trash to rot completely. Also, this is a good time to spread the amount of lime suggested in the soil test report. If your tractor is too small to prepare the soil correctly, have your fields custom plowed and disced a few months before the date of planting.Nematode pests and e quipment for control In Florida, several types of nematodes live in the soil and harm the roots of many plants. Normally, you cannot see these tiny worms, but you can see the root injury. Plant roots that look knotted w ill contain rootknot nematodes. Other nematodes may reduce the growth of small feeder roots or plants may have short, stubby roots. Fleshy roots of crops like sweet potatoes may be cracked and deformed. Severe root injury often will cause stunted plant growth, yellow leaves, or even dead plants. Yields and quality of most vegetables will be reduced. If you have seen these injury symptoms or think nematodes may infest your field, obtain a Nematode Sample Kit from your local Extension Office. Follow the instructions carefully and send your sample to the Nematode Assay Laboratory at the University of Florida in Gainesville. For a small fee, the kinds of nematodes f ound in your soil sample will be identified and a report sent to you. The report also will contain s uggested control methods.

For a few vegetables, non-fumigant nematicides in either granular or liquid formulations will provide satisfactory control of nematodes. These nematicides dissolve in the soil water,, and kill nematodes by contact with the chemical. Because non-fumigant nematicides move only short distances in the soil water, uniform application is essential. When deciding which type of nematicide to purchase, consider the cost and amount of nematode control needed for each crop listed on the label. Before you apply a nematicide, plow and disc all live plants and roots that may contain nematodes. Let the plant trash rot for several weeks. Fumigant nematicides should be applied two to three weeks before the intended planting date. If the soil remains cool and wet after application of fumigants, wait an additional week before planting to allow the nematicide extra time to escape. Lightly cultivate or disc the surface of the field to allow remaining nematicide fumes to escape before planting. Be careful to avoid deep cultivation and mixing untreated soil with the treated area. For non-fumigant nematicides, apply to the soil surface and incorporate 2 to 4 inches just before or during planting.Fertilizer pl acement, tim ing and appli cation equipment Decisions regarding amounts of nitrogen (N), phosphate (P0), and potash (KO) fertilizer elements to25 2apply should be based on both soil test results and the specific needs of the vegetable crop. By studying your soil test report and following the suggested fer tilizer program, your crop can depend partially on residual quantities of harvested when plant nutrients are supplied throughout theBedding and planting Vegetables grown on most soils in Florida must be planted on raised beds to insure adequate drainage during intense rains. Bed shapes and heights vary depending on the crop, soil type, and whether plastic mulch is used to cover the bed. Beds are formed with disc hillers and compacted with a bed press before plastic film is secured over the bed. For full-bed plastic mulch culture, basic fertilizers are mixed in the soil and certain nematicides or multipurpose soil fumigants are applied during bedding before the mulch is secured. Purchase quality seed with high germination percentages to help insure uniform stands of vigorous growing vegetables. Direct-seeded vegetables should be planted in a well-prepared moist seedbed to promote uniform germination and emergence. Mechanical planters, both tractor mounted and hand operated, are available with various plates for metering and planting different sized vegetable seed. After seedlings emerge, most vegetables can be thinned to the desired stand. Transplants of tomatoes, cabbage, or strawberries, and vine cuttings or slips of sweet potatoes, often are planted in the production field. Cabbage or pepper transplants are grown in special nurseries and carefully dug for transplanting. A vegetable transplanter can be used to plant most "bare-root" transplants at regular spacings in the field. To start the plants quickly, mix 4 to 6 pounds of a starter fer tilizer such as 10-52-8 which contains soluble sources of phosphorus and other nutrients in 100 gallons of water. Apply 1 to 2 cups of the

Special transplanting sleds normally are used to plant this type of transplant. In every case, you must either grow or buy vigorous, pest free transplants. Completely fumigate the nursery soil prior to planting your vegetable seed to insure pest-free transplants. Whenever possible, buy "certified" transplants or plant materials such as sweet potato slips to reduce the possibility of intr oducing certain pests into your production fields.Weed control and equipment Effective weed control begins by planning a year-insecticides and fungicides, but not herbicides.

Overhead systems generally costmarket for your produce. more to purchase, but are durable and can be used in certain situations to prevent frost injury. In contrast, drip systems are less expensive to install and require less irrigation water and a smaller pump. However, drip systems require regular maintenance with replacement of drip lines each year or after each crop. For more information about irrigating your vegetables, read the publications about irrigation listed in Appendix F. You can test your soil for moisture by removing a handful of soil from the root zone and squeezing. If the soil crumbles and does not keep the shape of your hand, it is too dry and you need to irrigate. Otherwise, you can wait a few more days and test again. Generally, most sandy soils in Florida should be irrigated with an inch of water every 5 to 7 days depending on the weather.HARVESTING, HA NDLING, STORING AND DISPLAYING VEGETABLESHarvesting vegetables at optimum maturity requiresand harvest duration.

WhenMARKETING OPTIONS AND BUSINESS DECISIONSSeveral marketing options exist for selling a variety of produce items. Market gardeners often can develop a reputation of providing dependable supplies of quality vegetables for either wholesale produce buyers, local market outlets, or both. Local markets include "U-pick" operations, roadside markets, door-to-door sales, retail markets, community markets, and other types of marketing arrangements. Imaginative market gardeners sometimes develop a specialty market such as selling organically grown vegetables or supplying fresh, shelled southern peas to a retail store. Obtain more information about marketing your vegetables by reading the publications listed in the Marketing section of Appendix F. Planning your production and marketing schedule requires information about crop yields, harvest frequency, supply approximately 30 bushels of eggplant per

Other useful information can be estimated from these data listed in Appendices A through E. REMEMBER however, that these data are averages or estimates which depend on many factors. As you study and gain experience in your particular region of the state, modify this information to improve your planning and decisionmaking process. Always evaluate su ccess by keeping a record of production expenses and sales r eceipts. Obtain Farm Record Books from your County Extension Agent and figure your profit or loss. Compare the actual production costs with your planning budgets to determine which production and marketing activ ities can be improved to increase your production efficiencies and profits. A careful and honest evaluation can increase your success and the satisfaction of growing quality vegetables for profit.APPENDIX A.
