Crops have been harvested by hand throughout most of human history.
In
agriculture, 'harvesting' is the process of
gathering mature
crops from the
fields. Reaping is the harvesting of grain crops. The harvest marks the end of the growing season, or the growing cycle for a particular crop. ''Harvesting'' in general usage includes an immediate
post-harvest handling, all of the actions taken immediately after removing the crop—cooling, sorting, cleaning, packing—up to the point of further on-farm processing, or shipping to the wholesale or consumer market.
Harvest timing is a critical decision, that balances the likely
weather conditions with the degree of crop maturity. Weather conditions such as
frost, and unseasonably warm or cold periods, can affect
yield and quality. An earlier harvest date may avoid damaging conditions, but result in poorer yield and quality. Delaying harvest may result in a better harvest, but increases the
risk of weather problems. Timing of the harvest often involves a significant degree of
gambling.
On smaller
farms with minimal
mechanization, harvesting is the most
labor-intensive activity of the growing season. On large, mechanized farms, harvesting utilizes the most expensive and sophisticated
farm machinery, like the
combine harvester.
''Harvest'' commonly refers to
grain and produce, but is used in reference to
fish and
timber. The term ''harvest'' is also used within the context of
irrigation where ''water harvesting'' is referred to as the collection and run-off of rainwater for agricultural or domestic uses.
Before the 16th century Harvest was the term usually used to refer to the season
Autumn. However as more people gradually moved from working the land to living in towns (especially those who could read and write, the only people whose use of language we now know), the word became to refer to the actual activity of reaping, rather than the time of year, and the terms Fall and Autumn began to replace it.
