Vegetable farming is the growing of vegetables for human
consumption.
Traditionally it was done in the soil in small rows or
blocks, often primarily for consumption on the farm, with the excess sold in
nearby towns. Later, farms on the edge of large communities could specialize in
vegetable production, with the short distance allowing the farmer to get his
produce to market while still fresh. The three sisters method used by Native
Americans (specifically the Haudenosaunee/Iroquois) grew squash, beans and corn
together so that the plants enhanced each other's growth. Planting in long rows
allows machinery to cultivate the fields, increasing efficiency and output;
however, the diversity of vegetable crops requires a number of techniques to be
used to optimize the growth of each type of plant. Some farms, therefore,
specialize in one vegetable; others grow a large variety. Due to the needs to
market vegetables while fresh, vegetable gardening has high labor demands. Some
farms avoid this by running u-pick operations where the customers pick their
own produce. The development of ripening technologies and refrigeration has
reduced the problems with getting produce to market in good condition.
Over the past 100 years a new technique has emerged—raised
bed gardening, which has increased yields from small plots of soil without the
need for commercial, energy-intensive fertilizers. Modern hydroponic farming
produces very high yields in greenhouses without using any soil.
Several economic models exist for vegetable farms: farms may
grow large quantities of a few vegetables and sell them in bulk to major
markets or middlemen, which requires large growing operations; farms may
produce for local customers, which requires a larger distribution effort; farms
may produce a variety of vegetables for sale through on-farm stalls, local
farmer's markets, u-pick operations. This is quite different from commodity
farm products like wheat and maize which do not have the ripeness problems and
are sold off in bulk to the local granary. Large cities often have a central
produce market which handles vegetables in a commodity-like manner, and manages
distribution to most supermarkets and restaurants.
In America, vegetable farms are in some regions known as
truck farms; "truck" is a noun for which its more common meaning
overshadows its historically separate use as a term for "vegetables grown
for market". Such farms are sometimes called muck farms, after the dark
black soil in which vegetables grow well.
