Vegetables are important sources of nutrition that are classified by plant part or family. There are various systems for vegetable production including organic farming, integrated crop management, backyard gardening, and commercial market or truck farming. Key components of vegetable production are land, capital, labor, and technology. Environmental factors like soil fertility, water, temperature, sunlight, and wind influence crop growth, as do biological factors such as weeds, pests, and microorganisms. Proper cultural management practices including site selection, land preparation, and care are needed to produce vegetables.
