(Wikipedia source) Horticulture is the industry and science of plant cultivation including the process of preparing soil for the planting of seeds, tubers, or cuttings. Horticulturists work and conduct research in the disciplines of plant propagation andcultivation, crop production, plant breeding and genetic engineering, plant biochemistry, and plant physiology. The work basically involves fruits, berries, nuts, vegetables, flowers, trees, shrubs, and turf. Horticulturists work to improve crop yield, quality, nutritional value, and resistance to insects, diseases, and environmental stresses. Horticulture usually refers to gardening on a smaller scale, while agriculture refers to the large-scale cultivation of crops. The wordhorticulture comes from the Latin hortus meaning garden, and cultus,  meaning to cultivate.
Horticulture involves Eight areas of study, which can be grouped into two broad sections – ornamentals and edibles:
- Arboriculture is the study of, and the selection, planting, care, and removal of, individual trees, shrubs, vines, and other perennial woody plants.
- Floriculture includes the production and marketing of floral crops.
- Landscape horticulture includes the production, marketing and maintenance of landscape plants.
- Olericulture includes the production and marketing of vegetables.
- Pomology includes the production and marketing of fruits.
- Viticulture includes the production and marketing of grapes.
- Oenology includes all aspects of wine and winemaking.
- Postharvest physiology involves maintaining the quality of and preventing the spoilage of horticultural crops.
Horticulture primarily differs from agriculture in two ways, firstly it generally encompasses a smaller scale of cultivation, using small plots of mixed crops rather than large fields of single crops. Secondly horticultural cultivations generally include a wide variety of crops, even including fruit trees with ground crops. Agricultural cultivations however as a rule focus on one primary crop. In pre-contact North America the semi-sedentary horticultural communities of the Eastern Woodlands (growing maize, squash and sunflower) contrasted markedly with the mobile hunter-gatherer communities of the Plains people. In Central America, Maya horticulture involved augmentation of the forest with useful trees such aspapaya, avocado, cacao, ceiba and sapodilla. In the cornfields, multiple crops were grown such as beans (using cornstalks as supports), squash, pumpkins and chilli peppers, in some cultures tended mainly or exclusively by women.
