Sweet potato in the context of Potato

A grain is a small, hard, dry fruit (caryopsis) – with or without an attached hull layer – harvested for human or animal consumption. A grain crop is a grain-producing plant. The two main types of commercial grain crops are cereals and legumes.

After being harvested, dry grains are more durable than other staple foods, such as starchy fruits (plantains, breadfruit, etc.) and tubers (sweet potatoes, cassava, and more). This durability has made grains well suited to industrial agriculture, since they can be mechanically harvested, transported by rail or ship, stored for long periods in silos, and milled for flour or pressed for oil. Thus, the grain market is a major global agricultural market that includes crops such as maize, rice, soybeans, wheat and other grains.

Orange is the colour between yellow and red on the spectrum of visible light. The human eyes perceive orange when observing light with a dominant wavelength between roughly 585 and 620 nanometres. In traditional colour theory, it is a secondary colour of pigments, produced by mixing yellow and red. In the RGB colour model, it is a tertiary colour. It is named after the fruit of the same name.

The orange colour of many fruits and vegetables, such as carrots, pumpkins, sweet potatoes, and oranges, comes from carotenes, a type of photosynthetic pigment. These pigments convert the light energy that the plants absorb from the Sun into chemical energy for the plants' growth. Similarly, the hues of autumn leaves are from the same pigment after chlorophyll is removed.

Tubers are a type of enlarged structure that plants use as storage organs for nutrients, derived from stems or roots. Tubers help plants perennate (survive winter or dry months), provide energy and nutrients, and are a means of asexual reproduction.

Stem tubers manifest as thickened rhizomes (underground stems) or stolons (horizontal connections between organisms); examples include the potato and yam. The term root tuber describes modified lateral roots, as in sweet potato, cassava, and dahlia.

Asterids are a large clade (monophyletic group) of flowering plants, composed of 17 orders and more than 80,000 species, about a third of the total flowering plant species. The asterids are divided into the unranked clades lamiids (8 orders) and campanulids (7 orders), and the single orders Cornales and Ericales. Well-known asterids include dogwoods and hydrangeas (order Cornales), tea, blueberries, cranberries, kiwifruit, Brazil nuts, argan, sapote, and azaleas (order Ericales), sunflowers, lettuce, common daisy, yacon, carrots, celery, parsley, parsnips, ginseng, ivies, holly, honeysuckle, elder, and valerian (clade campanulids), borage, forget-me-nots, comfrey, coffee, frangipani, gentian, pong-pong, oleander, periwinkle, basil, mint, rosemary, sage, oregano, thyme, lavender, wild dagga, olives, ash, teak, foxgloves, lilac, jasmine, snapdragons, African violets, butterfly bushes, sesame, psyllium, potatoes, eggplants, tomatoes, chilli peppers, tobacco, petunias, morning glory, and sweet potato (clade lamiids).

Most of the taxa belonging to this clade had been referred to as Asteridae in the Cronquist system (1981) and as Sympetalae in earlier systems. The name asterids (not necessarily capitalised) resembles the earlier botanical name but is intended to be the name of a clade rather than a formal ranked name, in the sense of the ICBN.

The Tày people, also known as the Thổ, T'o, Tai Tho, Ngan, Phen, Thu Lao, or Pa Di, is a Central Tai-speaking ethnic group who live in northern Vietnam. According to a 2019 census, there are 1.8 million Tày people living in Vietnam. This makes them the second largest ethnic group in Vietnam after the majority Kinh (Vietnamese) ethnic group. Most live in northern Vietnam in the Cao Bằng, Lạng Sơn, Bắc Kạn, Thái Nguyên, and Quảng Ninh provinces, along the valleys and the lower slopes of the mountains. They also live in some regions of the Bắc Ninh and Bắc Giang provinces. They inhabit fertile plains and are generally agriculturalists, mainly cultivating rice. They also cultivate maize, and sweet potato among other things.

Convolvulaceae (/kənˌvɒlvjəˈleɪsi.iː, -aɪ/), commonly called the bindweeds or morning glories, is a family of about 60 genera and more than 1,650 species. These species are primarily herbaceous vines, but also include trees, shrubs and herbs. The tubers of several species are edible, the best known of which is the sweet potato.

Mesoamerican cuisine – (covering Belize, El Salvador, Guatemala, Honduras, Nicaragua, northern Costa Rica and Mexico) has four main staples: maize (many varieties based on what climate it is grown in), beans, squash and chili. Other plant-based foods used include amaranth, avocado, cassava, cherimoya, chia, chocolate, guava, nanche, pineapple, sapodilla, sweet potatoes, yucca and zapote.

Historically, various methods and techniques were employed to store, prepare and preserve the foods, most of which remain in use today. Hernán Cortés introduced rice and wheat to Mesoamerica, prior to which time milpa (known as the cornfield) was one of the main sources of sustenance.

This list of sweet potato cultivars provides some information about varieties and cultivars of sweet potato (Ipomoea batatas). The sweet potato was first domesticated in the Americas more than 5,000 years ago. As of 2013, there are approximately 7,000 sweet potato cultivars. People grow sweet potato in many parts of the world, including New Zealand, Australia, the Philippines, Japan, Hawaii, China, and North America. However, sweet potato is not widely cultivated in Europe.

People breed sweet potatoes mainly either for food (their nutritious storage roots) or for their attractive vines. (The variety 'Vardaman' is grown for both.) The first table below lists sweet potato cultivars grown for their edible roots; the second table lists cultivars bred as ornamental vines. In the first table, the Parentage column briefly explains how the sweet potato cultivar was bred. Sweet potato plants with desirable traits are selectively bred to produce new cultivars.

The Solanales are an order of flowering plants, included in the asterid group of the eudicots. Well-known members of Solanales include potatoes, sweet potatoes, eggplants, tomatoes, chili peppers, tobacco, petunias, nightshades, and morning glory. Some older sources used the name Polemoniales for this order.

Aspergillus oryzae, also known as kōji mold (Japanese: ニホンコウジカビ (日本麹黴), Hepburn: nihon kōji kabi), is a mold used in East Asia to saccharify rice, sweet potato, and barley in the making of alcoholic beverages such as sake and shōchū, and also to ferment soybeans for making soy sauce and miso. It is one of the different koji molds used for food fermentation.

However, in the production of fermented foods of soybeans such as soy sauce and miso, Aspergillus sojae is sometimes used instead of A. oryzae. A. oryzae is also used for the production of rice vinegars. Barley kōji (麦麹) or rice kōji (米麹) are made by fermenting the grains with A. oryzae hyphae.

The cuisines of Oceania include those found on Australia, New Zealand, and New Guinea, and also cuisines from many other islands or island groups throughout Oceania.

Since the region of Oceania consists of islands, seafood is a prominent part of the diet, with vegetables such as potatoes, sweet potato, taro and yams being the main starch. Coconut, and its derivative products such as coconut milk, coconut oil and coconut sugar, are important ingredients in the tropics of Oceania.

Benue is a State in the North Central region of Nigeria. It is popularly referred to as part of the Middle belt. It has an estimated population of about 4,253,641 in the 2006 census. The state was created in 1976 and was among the seven states created at that time.

The state borders Nasarawa State to the North; Taraba State to the East; Kogi State to the West; Enugu State to the South-West; Ebonyi and Cross-Rivers State to the South; and has an international border with Cameroon to the South-East. It is inhabited predominantly by the Tiv, Idoma and Igede people. Minority ethnic groups in Benue are Etulo,hausa and Jukun people etc. Its capital is Makurdi. Benue is a rich agricultural region; common crops cultivated in the state include oranges, yams, mangoes, sweet potatoes, cassava, soya bean, guinea corn, flax, sesame, rice, groundnuts and palm trees.
