Crop rotation is the practice of growing a series of different types of crops in the same area across a sequence of growing seasons. This practice reduces the reliance of crops on one set of nutrients, pest and weed pressure, along with the probability of developing resistant pests and weeds.
In agriculture, monoculture is the practice of growing one crop species in a field at a time. Monoculture is widely used in intensive farming and in organic farming: both a 1,000-hectare cornfield and a 10-ha field of organic kale are monocultures. Monoculture of crops has allowed farmers to increase efficiency in planting, managing, and harvesting, mainly by facilitating the use of machinery in these operations, but monocultures can also increase the risk of diseases or pest outbreaks. This practice is particularly common in industrialized nations worldwide. Diversity can be added both in time, as with a crop rotation or sequence, or in space, with a polyculture or intercropping.
A farmer is a person engaged in agriculture, raising living organisms for food or raw materials. The term usually applies to people who do some combination of raising field crops, orchards, vineyards, poultry, or other livestock. A farmer might own the farmland or might work as a laborer on land owned by others. In most developed economies, a "farmer" is usually a farm owner (landowner), while employees of the farm are known as farm workers. However, in other older definitions a farmer was a person who promotes or improves the growth of plants, land, or crops or raises animals by labor and attention.
The British Agricultural Revolution, or Second Agricultural Revolution, was an unprecedented increase in agricultural production in Britain arising from increases in labor and land productivity between the mid-17th and late 19th centuries. Agricultural output grew faster than the population over the hundred-year period ending in 1770, and thereafter productivity remained among the highest in the world. This increase in the food supply contributed to the rapid growth of population in England and Wales, from 5.5 million in 1700 to over 9 million by 1801, though domestic production gave way increasingly to food imports in the 19th century as the population more than tripled to over 35 million.
The open-field system was the prevalent agricultural system in much of Europe during the Middle Ages and lasted into the 20th century in Russia, Iran, and Turkey. Each manor or village had two or three large fields, usually several hundred acres each, which were divided into many narrow strips of land. The strips or selions were cultivated by peasants, often called tenants or serfs. The holdings of a manor also included woodland and pasture areas for common usage and fields belonging to the lord of the manor and the religious authorities, usually Roman Catholics in medieval Western Europe. The farmers customarily lived in separate houses in a nucleated village with a much larger manor house and church nearby. The open-field system necessitated co-operation among the residents of the manor.
Dryland farming and dry farming encompass specific agricultural techniques for the non-irrigated cultivation of crops. Dryland farming is associated with drylands, areas characterized by a cool wet season followed by a warm dry season. They are also associated with arid conditions, areas prone to drought and those having scarce water resources.
Agriculture in the Russian Empire throughout the 19th-20th centuries Russia represented a major world force, yet it lagged technologically behind other developed countries. Imperial Russia was amongst the largest exporters of agricultural produce, especially wheat. The Free Economic Society of 1765 to 1919 made continuing efforts to improve farming techniques.
Roman agriculture describes the farming practices of ancient Rome, during a period of over 1000 years. From humble beginnings, the Roman Republic and the Roman Empire expanded to rule much of Europe, northern Africa, and the Middle East and thus comprised many agricultural environments of which the Mediterranean climate of dry, hot summers and cool, rainy winter was the most common. Within the Mediterranean area, a triad of crops were most important: grains, olives, and grapes.
During the Sangam age, 800 BCE – 300 CE, agriculture was the main vocation of the Tamil. 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.
Incan agriculture was the culmination of thousands of years of farming and herding in the high-elevation Andes mountains of South America, the coastal deserts, and the rainforests of the Amazon basin. These three radically different environments were all part of the Inca Empire and required different technologies for agriculture. Inca agriculture was also characterized by the variety of crops grown, the lack of a market system and money, and the unique mechanisms by which the Incas organized their society. Andean civilization was "pristine"—one of six civilizations worldwide which were indigenous and not derivative from other civilizations. Most Andean crops and domestic animals were likewise pristine—not known to other civilizations. Potatoes, tomatoes, chile peppers, and quinoa were among the many unique crops; Camelids and guinea pigs were the unique domesticated animals.
Agriculture accounts for 22 percent of Cambodia’s GDP, and employs about 3 million people.
In 2020, approximately 80% of Chad's labor force was employed in the agricultural sector. This sector of the economy accounts for 52.3% of the GDP, as of 2017. With the exception of cotton production, some small-scale sugar cane production, and a portion of the peanut crop, Chad's agriculture consists of subsistence food production.
Agriculture in Sudan plays an important role in that country's economy. Agriculture and livestock raising are the main sources of livelihood for most of the Sudanese population. It was estimated that, as of 2011, 80 percent of the labor force were employed in that sector, including 84 percent of the women and 64 percent of the men.
Despite the crisis in Syria, agriculture remains a key part of the economy. The sector still accounts for an estimated 26 percent of gross domestic product (GDP) and represents a critical safety net for the 6.7 million Syrians – including those internally displaced – who still remain in rural areas. However, agriculture and the livelihoods that depend on it have suffered massive losses . Today, food production is at a record low and around half the population remaining in Syria are unable to meet their daily food needs.
Indigenous horticulture is practised in various ways across all inhabited continents. Indigenous refers to the native peoples of a given area and horticulture is the practice of small-scale intercropping.
Costa Rican agriculture plays a profound part in the country's gross domestic product (GDP). It makes up about 6.5% of Costa Rica's GDP, and 14% of the labor force. Depending upon location and altitude, many regions differ in agricultural crops and techniques. The main exports include: bananas, pineapples, coffee, sugar, rice, vegetables, tropical fruits, ornamental plants, corn, potatoes and palm oil.
Farming systems in India are strategically utilized, according to the locations where they are most suitable. The farming systems that significantly contribute to the agriculture of India are subsistence farming, organic farming, industrial farming. Regions throughout India differ in types of farming they use; some are based on horticulture, ley farming, agroforestry, and many more. Due to India's geographical location, certain parts experience different climates, thus affecting each region's agricultural productivity differently. India is very dependent on its monsoon cycle for large crop yields. India's agriculture has an extensive background which goes back to at least 9 thousand years. In India, in the alluvial plains of the Indus River in Pakistan, the old cities of Mohenjo-Daro and Harappa experienced an apparent establishment of an organized farming urban culture. That society, known as the Harappan or Indus civilization, flourished until shortly after 4000 BP; it was much more comprehensive than those of Egypt or Babylonia and appeared earlier than analogous societies in northern China. Currently, the country holds the second position in agricultural production in the world. In 2007, agriculture and other industries made up more than 16% of India's GDP. Despite the steady decline in agriculture's contribution to the country's GDP, agriculture is the biggest industry in the country and plays a key role in the socio-economic growth of the country. India is the second-largest producer of wheat, rice, cotton, sugarcane, silk, groundnuts, and dozens more. It is also the second biggest harvester of vegetables and fruit, representing 8.6% and 10.9% of overall production, respectively. The major fruits produced by India are mangoes, papayas, sapota, and bananas. India also has the biggest number of livestock in the world, holding 281 million. In 2008, the country housed the second largest number of cattle in the world with 175 million.
Collective farming and communal farming are various types of "agricultural production in which multiple farmers run their holdings as a joint enterprise". There are two broad types of communal farms: agricultural cooperatives, in which member-owners jointly engage in farming activities as a collective; and state farms, which are owned and directly run by a centralized government. The process by which farmland is aggregated is called collectivization. In some countries, there have been both state-run and cooperative-run variants. For example, the Soviet Union had both kolkhozy and sovkhozy.
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.
