Soybean in the context of "High-yielding variety"

The modern combine harvester, also called a combine, is a machine designed to harvest a variety of cultivated seeds. Combine harvesters are one of the most economically important labour-saving inventions, significantly reducing the fraction of the population engaged in agriculture. Among the crops harvested with a combine are wheat, rice, oats, rye, barley, corn (maize), sorghum, millet, soybeans, flax (linseed), sunflowers and rapeseed (canola). The separated straw (consisting of stems and any remaining leaves with limited nutrients left in it) is then either chopped onto the field and ploughed back in, or laid out in rows, ready to be baled and used for bedding and cattle feed.

The name of the machine is derived from the fact that the harvester combined multiple separate harvesting operations – reaping, threshing or winnowing and gathering – into a single process around the start of the 20th century. A combine harvester still performs its functions according to those operating principles. The machine can easily be divided into four parts, namely: the intake mechanism, the threshing and separation system, the cleaning system, and finally the grain handling and storage system. Electronic monitoring assists the operator by providing an overview of the machine's operation, and the field's yield.

Soybean oil (British English: soyabean oil) is a vegetable oil extracted from soybean (Glycine max) legumes. It is one of the most widely consumed cooking oils and the second most consumed vegetable oil. As a drying oil, processed soybean oil is also used as a base for printing inks (soy ink) and oil paints.

An eraser (also known as a rubber in some Commonwealth countries, including South Africa from which the material first used got its name) is an article of stationery that is used for removing marks from paper or skin (e.g. parchment or vellum). Erasers have a rubbery consistency and come in a variety of shapes, sizes, and colors. Some pencils have an eraser on one end. Less expensive erasers are made from synthetic rubber and synthetic soy-based gum, but more expensive or specialized erasers are made from vinyl, plastic, or gum-like materials.

At first, erasers were invented to erase mistakes made with a pencil; later, more abrasive ink erasers were introduced. The term is also used for things that remove marks from chalkboards and whiteboards.

Rice polyculture is the cultivation of rice and another crop simultaneously on the same land. The practice exploits the mutual benefit between rice and organisms such as fish and ducks: the rice supports pests which serve as food for the fish and ducks, while the animals' excrement serves as fertiliser for the rice. The result is an additional crop, with reduced need for inputs of fertiliser and pesticides. In addition, the reduction of pests such as mosquito larvae and snails may reduce mosquito-borne diseases such as malaria and dengue fever, and snail-born parasites such as the trematodes which cause schistosomiasis. The reduction in chemical inputs may reduce environmental harms caused by their release into the environment. The increased biodiversity may reduce methane emissions from rice fields.

Some rice-animal polycultures, including rice-fish systems in China and rice-duck farming in China and Southeast Asia, have been practised for centuries, while others have been developed more recently. The use of intercropping with plants such as maize and soybean, planted on levees between rice terraces, may help to reduce rice pests such as brown planthopper.

A food allergy is an abnormal immune response to food. The symptoms of the allergic reaction may range from mild to severe. They may include itchiness, swelling of the tongue, vomiting, diarrhea, hives, trouble breathing, or low blood pressure. This typically occurs within minutes to several hours of exposure. When the symptoms are severe, it is known as anaphylaxis. A food intolerance and food poisoning are separate conditions, not due to an immune response.

Common foods involved include cow's milk, peanuts, eggs, shellfish, fish, tree nuts, soy, wheat, and sesame. The common allergies vary depending on the country. Risk factors include a family history of allergies, vitamin D deficiency, obesity, and high levels of cleanliness. Allergies occur when immunoglobulin E (IgE), part of the body's immune system, binds to food molecules. A protein in the food is usually the problem. This triggers the release of inflammatory chemicals such as histamine. Diagnosis is usually based on a medical history, elimination diet, skin prick test, blood tests for food-specific IgE antibodies, or oral food challenge.

A bean is the seed of plants in many genera of the legume family (Fabaceae) used as a vegetable for human consumption or animal feed. The seeds are sold fresh or preserved through drying (a pulse). Beans have been cultivated since the seventh millennium BCE in Thailand, and since the second millennium BCE in Europe and in Peru. Most beans, with the exception of peas, are summer crops. As legumes, the plants fix nitrogen and form seeds with a high protein content. They are produced on a scale of millions of tons annually in many countries; India is the largest producer.

Dried beans are traditionally soaked and boiled, and used in traditional dishes throughout the world including salads, soups, and stews such as chili con carne. Some are processed into tofu; others are fermented to form tempeh. Guar beans are used for their gum. The unripe seedpods of some varieties are also eaten whole as green beans or edamame (immature soybean). Some types are sprouted to form beansprouts.

China has been the source of many innovations, scientific discoveries and inventions. Below is an alphabetical list of inventions and discoveries made by Neolithic cultures of China and those of its prehistorical early Bronze Age before the palatial civilization of the Shang dynasty (c. 1650 – c. 1050 BC). These include the Bronze Age Erlitou culture and the semi-legendary Xia dynasty that, unlike the Shang, is not yet confirmed to have existed with evidence of contemporary texts.

The contemporaneous Peiligang and Pengtoushan cultures represent the oldest Neolithic cultures of China and were formed around 7000 BC. Some of the first inventions of Neolithic China include semilunar and rectangular stone knives, stone hoes and spades, the cultivation of millet and the soybean, the refinement of sericulture, rice cultivation, the creation of pottery with cord-mat-basket designs, the creation of pottery vessels and pottery steamers and the development of ceremonial vessels and scapulimancy for purposes of divination. The British sinologist Francesca Bray argues that the domestication of the ox and buffalo during the Longshan culture (c. 3000 – c. 2000 BC) period, the absence of Longshan-era irrigation or high-yield crops, full evidence of Longshan cultivation of dry-land cereal crops which gave high yields "only when the soil was carefully cultivated," suggest that the plow was known at least by the Longshan culture period and explains the high agricultural production yields which allowed the rise of Chinese civilization during the Shang dynasty. Later inventions such as the multiple-tube seed drill and the heavy moldboard iron plow enabled China to sustain a much larger population through greater improvements in agricultural output.

Macoupin County is a county located in the U.S. state of Illinois. According to the 2020 census, it had a population of 44,967. The county seat is Carlinville.

The primary industry is agriculture, consisting of crops of corn (maize), soybeans, and some wheat.
