Harvesting is the process of gathering a ripe crop from the fields. Reaping is the cutting of grain or pulse for harvest, typically using a scythe, sickle, or reaper. [1] 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, such as the combine harvester. Process automation has increased the efficiency of both the seeding and harvesting process. Specialized harvesting equipment utilizing conveyor belts to mimic gentle gripping and mass transport replaces the manual task of removing each seedling by hand. [2] The term "harvesting" in general usage may include immediate postharvest handling, including cleaning, sorting, packing, and cooling.

The completion of harvesting marks the end of the growing season, or the growing cycle for a particular crop, and the social importance of this event makes it the focus of seasonal celebrations such as harvest festivals, found in many religions.

Etymology

"Harvest", a noun, came from the Old English word hærf-est (coined before the Angles moved from Angeln to Great Britain) [3] meaning "autumn" (the season), "harvest-time", or "August". (It continues to mean "autumn" in British dialect, and "season of gathering crops" generally.) "The harvest" came to also mean the activity of reaping, gathering, and storing grain and other grown products during the autumn, and also the grain and other grown products themselves. "Harvest" was also verbified: "To harvest" means to reap, gather, and store the harvest (or the crop). People who harvest and equipment that harvests are harvesters; while they do it, they are harvesting.

Crop failure

Crop failure (also known as harvest failure) is an absent or greatly diminished crop yield relative to expectation, caused by the plants being damaged, killed, or destroyed, or affected in some way that they fail to form edible fruit, seeds, or leaves in their expected abundance.

Crop failures can be caused by catastrophic events such as plant disease outbreaks (see e.g. Great Famine (Ireland)), heavy rainfall, volcanic eruptions, storms, floods, or drought, or by slow, cumulative effects of soil degradation, too-high soil salinity, erosion, desertification, usually as results of drainage, overdrafting (for irrigation), overfertilization, or overexploitation.

In history, crop failures and subsequent famines have triggered human migration, rural exodus, etc.

The proliferation of industrial monocultures, with their reduction in crop diversity and dependence on heavy use of artificial fertilizers and pesticides, has led to overexploited soils that are nearly incapable of regeneration. Over years, unsustainable farming of land degrades soil fertility and diminishes crop yield. With a steadily growing world population and local overpopulation, even slightly diminishing yields are already the equivalent to a partial harvest failure. Fertilizers obviate the need for soil regeneration in the first place, and international trade prevents local crop failures from developing into famines.

Other uses

Harvesting commonly refers to grain and produce, but also has other uses: fishing and logging are also referred to as harvesting. The term harvest is also used in reference to harvesting grapes for wine. Within the context of irrigation, water harvesting refers to the collection and run-off of rainwater for agricultural or domestic uses. Instead of harvest, the term exploit is also used, as in exploiting fisheries or water resources. Energy harvesting is the process of capturing and storing energy (such as solar power, thermal energy, wind energy, salinity gradients, and kinetic energy) that would otherwise go unexploited. Body harvesting, or cadaver harvesting, is the process of collecting and preparing cadavers for anatomical study. In a similar sense, organ harvesting is the removal of tissues or organs from a donor for purposes of transplanting.

In a non-agricultural sense, the word "harvesting" is an economic principle which is known as an exit event or liquidity event. For example, if a person or business was to cash out of an ownership position in a company or eliminate their investment in a product, it is known as a harvest strategy. [4]

Canada

Harvesting or Domestic Harvesting in Canada refers to hunting, fishing, and plant gathering by First Nations, Métis, and Inuit in discussions of aboriginal or treaty rights. For example, in the Gwich'in Comprehensive Land Claim Agreement, "Harvesting means gathering, hunting, trapping or fishing..." [5] Similarly, in the Tlicho Land Claim and Self Government Agreement, "'Harvesting' means, in relation to wildlife, hunting, trapping or fishing and, in relation to plants or trees, gathering or cutting." [6]

    Cereal Grass of which the fruits are used as grain, or said fruits

    A cereal is any grass cultivated (grown) for the edible components of its grain, composed of the endosperm, germ, and bran. The term may also refer to the resulting grain itself. Cereal grain crops are grown in greater quantities and provide more food energy worldwide than any other type of crop and are therefore staple crops. Edible grains from other plant families, such as buckwheat (Polygonaceae), quinoa (Amaranthaceae) and chia (Lamiaceae), are referred to as pseudocereals.

    <i>Eleusine coracana</i> species of plant

    Eleusine coracana, or finger millet, is an annual herbaceous plant widely grown as a cereal crop in the arid and semiarid areas in Africa and Asia. It is commonly called kodo in Nepal where 877 accessions have been maintained by National Plant Genetic Resource Centre, Khumaltar, Nepal. It is a tetraploid and self-pollinating species probably evolved from its wild relative Eleusine africana.

    Intensive farming Type of agriculture using high inputs to try to get high outputs

    Intensive agriculture, also known as intensive farming and industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per cubic unit of agricultural land area. It is characterized by a low fallow ratio, higher use of inputs such as capital and labour, and higher crop yields per unit land area.

    Combine harvester machine that harvests grain crops

    The modern combine harvester, or simply combine, is a versatile machine designed to efficiently harvest a variety of grain crops. The name derives from its combining three separate harvesting operations—reaping, threshing, and winnowing—into a single process. Among the crops harvested with a combine are wheat, oats, rye, barley, corn (maize), sorghum, soybeans, flax (linseed), sunflowers and canola. The separated straw, left lying on the field, comprises the stems and any remaining leaves of the crop with limited nutrients left in it: the straw is then either chopped, spread on the field and ploughed back in or baled for bedding and limited-feed for livestock.

    Reaper Harvesting machine

    A reaper is a farm implement or person that reaps crops at harvest when they are ripe. Usually the crop involved is a cereal grass. The first documented reaping machines were Gallic reaper that was used in modern-day France during Roman times. The Gallic reaper involved a comb which collected the heads, with an operator knocking the grain into a box for later threshing.

    <i>Panicum virgatum</i> species of plant

    Panicum virgatum, commonly known as switchgrass, is a perennial warm season bunchgrass native to North America, where it occurs naturally from 55°N latitude in Canada southwards into the United States and Mexico. Switchgrass is one of the dominant species of the central North American tallgrass prairie and can be found in remnant prairies, in native grass pastures, and naturalized along roadsides. It is used primarily for soil conservation, forage production, game cover, as an ornamental grass, in phytoremediation projects, fiber, electricity, heat production, for biosequestration of atmospheric carbon dioxide, and more recently as a biomass crop for ethanol and butanol.

    Swather harvesting machine

    A swather, or windrower, is a farm implement that cuts hay or small grain crops and forms them into a windrow. "Swather" is predominantly the North American term for these machines. In Australia and other parts of the world, they are called "windrowers". They aid harvesting by speeding up the process of drying the crop down to a moisture content suitable for harvesting and storage.

    Agriculture in Mongolia

    Agriculture in Mongolia constitutes over 10% of Mongolia's annual Gross domestic product and employs one-third of the labor force. However, the high altitude, extreme fluctuation in temperature, long winters, and low precipitation provides limited potential for agricultural development. The growing season is only 95 – 110 days. Because of Mongolia's harsh climate, it is unsuited to most cultivation. Only 1% of the arable land in Mongolia is cultivated with crops, amounting to 1,322,000 hectares in 1998. The agriculture sector therefore remains heavily focused on nomadic animal husbandry with 75% of the land allocated to pasture, and cropping only employing 3% of the population. Crops produced in Mongolia include corn, wheat, barley, and potatoes. Animals raised commercially in Mongolia include sheep, goats, cattle, horses, camels, and pigs. They are raised primarily for their meat, although goats are valued for their hair which can be used to produce cashmere.

    During the Sangam age, 500 BCE – 300 CE, agriculture was the main vocation of the Tamils. It was considered a necessity for life, and hence was treated as the foremost among all occupations. The farmers or the Ulavar were placed right at the top of the social classification. As they were the producers of food grains, they lived with self-respect. Agriculture during the early stages of Sangam period was primitive, but it progressively got more efficient with improvements in irrigation, ploughing, manuring, storage and distribution. The ancient Tamils were aware of the different varieties of soil, the kinds of crops that can be grown on them and the various irrigation schemes suitable for a given region. These were also in Madras, Thanjore.

    <i>Paspalum scrobiculatum</i> species of plant

    Paspalum scrobiculatum, commonly called Kodo millet or Koda millet,, is an annual grain that is grown primarily in Nepal (not to confuse with Kodo and also in the India, Philippines, Indonesia, Vietnam, Thailand, and in West Africa from where it originated. It is grown as a minor crop in most of these areas, with the exception of the Deccan plateau in India where it is grown as a major food source. It is a very hardy crop that is drought tolerant and can survive on marginal soils where other crops may not survive, and can supply 450–900 kg of grain per hectare Kodo millet has large potential to provide nourishing food to subsistence farmers in Africa and elsewhere.

    Agricultural machinery Machinery used in farming or other agriculture

    Agricultural machinery is machinery used in farming or other agriculture. There are many types of such equipment, from hand tools and power tools to tractors and the countless kinds of farm implements that they tow or operate. Diverse arrays of equipment are used in both organic and nonorganic farming. Especially since the advent of mechanised agriculture, agricultural machinery is an indispensable part of how the world is fed.

    Gordie C. Hanna was a University of California-Davis agronomy professor who helped revolutionize the tomato-growing industry. He won the John Scott Award in 1976 for his development of a tomato variety capable of being machine-harvested. The variety came to be known as the "square tomato," being slightly blockier, preventing it from rolling off conveyor belts.

    The combine grain yield monitor is a device coupled with other sensors to calculate and record the crop yield or grain yield as a modern-day combine harvester operates. Yield monitors are a part of the precision agriculture products available to producers today that provide producers with the tools to reduce costs, increase yields, and increase efficiency. The present day grain yield monitor is designed to measure the harvested grain mass flow, moisture content, and speed to determine total grain harvested. In most cases today this is coupled with global positioning system to record yield and other spatially variable information across a field. This allows for the creation of a grain yield map which provides information on spatial variability and supports management decisions for producers.

    Corn production in the United States production of maize crop in the United States

    The production of corn plays a major role in the economy of the United States. The US is the largest corn producer in the world, with 96,000,000 acres (39,000,000 ha) of land reserved for corn production. Corn growth is dominated by west/north central Iowa and east central Illinois. Approximately 13% of its annual yield is exported.

    Agriculture in the Middle Ages

    Agriculture in the Middle Ages describes the farming practices, crops, technology, and agricultural society and economy of Europe from the fall of the Western Roman Empire in 476 to approximately 1500. The Middle Ages are sometimes called the Medieval Age or Period. The Middle Ages are also divided into the Early, High, and Late Middle Ages. The early modern period followed the Middle Ages.
