Rice is a cereal grain and in its domesticated form is the staple food of over half of the world's population, particularly in Asia and Africa. Rice is the seed of the grass species Oryza sativa —or, much less commonly, Oryza glaberrima. Asian rice was domesticated in China some 13,500 to 8,200 years ago; African rice was domesticated in Africa about 3,000 years ago. Rice has become commonplace in many cultures worldwide; in 2021, 787 million tons were produced, placing it fourth after sugarcane, maize, and wheat. Only some 8% of rice is traded internationally. China, India, and Indonesia are the largest consumers of rice. A substantial amount of the rice produced in developing nations is lost after harvest through factors such as poor transport and storage. Rice yields can be reduced by pests including insects, rodents, and birds, as well as by weeds, and by diseases such as rice blast. Traditional rice polycultures such as rice-duck farming, and modern integrated pest management seek to control damage from pests in a sustainable way.
Lettuce is an annual plant of the family Asteraceae. It is most often grown as a leaf vegetable, but sometimes for its stem and seeds. Lettuce is most often used for salads, although it is also seen in other kinds of food, such as soups, sandwiches and wraps; it can also be grilled. One variety, celtuce, is grown for its stems, which are eaten either raw or cooked. In addition to its main use as a leafy green, it has also gathered religious and medicinal significance over centuries of human consumption. Europe and North America originally dominated the market for lettuce, but by the late 20th century the consumption of lettuce had spread throughout the world. As of 2021, world production of lettuce and chicory was 27 million tonnes, 53 percent of which came from China.
Oryza sativa is the much more common of the two rice species cultivated as a cereal, the other species being O. glaberrima, African rice. It was first domesticated in the Yangtze River basin in China 13,500 to 8,200 years ago.
Basmati, pronounced['bɑːsmət̪iː], is a variety of long, slender-grained aromatic rice which is traditionally grown in the Indian subcontinent, mainly India, Pakistan, Sri Lanka and Nepal. As of 2019, India accounted for 65% of the international trade in basmati rice, while Pakistan accounted for the remaining 35%. Many countries use domestically grown basmati rice crops; however, basmati is geographically exclusive to certain districts of India and Pakistan.
Jasmine rice is a long-grain variety of fragrant rice. Its fragrance, reminiscent of pandan and popcorn, results from the rice plant's natural production of aroma compounds, of which 2-acetyl-1-pyrroline is the most salient. A rapid loss of aromatic intensity leads many Southeast Asians and connoisseurs to prefer each year's freshly harvested "new crop" of jasmine rice. Jasmine rice is a variety of Oryza sativa.
Red rice is rice that is colored red due to natural anthocyanin content. It is usually eaten unpolished or partially polished, and has a red bran layer, rather than the more common pale brown. Red rice has a nutty flavor. It has the highest nutritional value among rices eaten with the bran intact.
Weedy rice, also known as red rice, is a variety of rice (Oryza) that produces far fewer grains per plant than cultivated rice and is therefore considered a pest. The name "weedy rice" is used for all types and variations of rice which show some characteristic features of cultivated rice and grow as weeds in commercial rice fields. Populations of weedy rice are found in many rice-growing regions. Weedy rice varieties generally have fragile stalks that self-seed before harvest. Variations of weedy rice adapt to a wide range of natural conditions.
Ambemohar is a fragrant rice variant grown in the foothills of the Western ghats region of the state of Maharashtra in India.
In the cuisine of Sikkim, in northeastern India, rice is a staple food, and fermented foods traditionally constitute a significant portion of the cuisine. Nepalese cuisine is popular, as Sikkim is the only state of India with an ethnic Nepali majority. Many restaurants in Sikkim serve various types of Nepalese cuisine, such as the Limbu, Newa and Thakali cuisines. Tibetan cuisine has also influenced Sikkimese cuisine. The combination of various cuisines has resulted in one specific cuisine.
Oryza rufipogon is a species of flowering plant in the family Poaceae. It is known as brownbeard rice, wild rice, and red rice. In 1965, Oryza nivara was separated off from O. rufipogon. The separation has been questioned, and some sources consider O. nivara to be a synonym of O. rufipogon. O. nivara may be treated as the annual form of O. rufipogon.
Agriculture in Bhutan has a dominant role in the Bhutan's economy. In 2000, agriculture accounted for 35.9% of GDP of the nation. The share of the agricultural sector in GDP declined from approximately 55% in 1985 to 33% in 2003. Despite this, agriculture remains the primary source of livelihood for the majority of the population. Pastoralism and farming are naturally complementary modes of subsistence in Bhutan.
Oryza glaberrima, commonly known as African rice, is one of the two domesticated rice species. It was first domesticated and grown in West Africa around 3,000 years ago. In agriculture, it has largely been replaced by higher-yielding Asian rice, and the number of varieties grown is declining. It still persists, making up an estimated 20% of rice grown in West Africa. It is now rarely sold in West African markets, having been replaced by Asian strains.
Japonica rice, sometimes called sinica rice, is one of the two major domestic types of Asian rice varieties. Japonica rice is extensively cultivated and consumed in East Asia, whereas in most other regions indica rice is the dominant type of rice. Japonica rice originated from Central China, where it was first domesticated along the Yangtze River basin approximately 9,500 to 6,000 years ago.
Perennial rice are varieties of long-lived rice that are capable of regrowing season after season without reseeding; they are being developed by plant geneticists at several institutions. Although these varieties are genetically distinct and will be adapted for different climates and cropping systems, their lifespan is so different from other kinds of rice that they are collectively called perennial rice. Perennial rice—like many other perennial plants—can spread by horizontal stems below or just above the surface of the soil but they also reproduce sexually by producing flowers, pollen and seeds. As with any other grain crop, it is the seeds that are harvested and eaten by humans.
Kalanamak is a scented rice of Nepal and India. Its name means black husk. This variety has been in cultivation since the original Buddhist period. It is popular in Himalayan Tarai of Nepal i.e., Kapilvastu, and eastern Uttar Pradesh, where it is known as the scented black pearl. It was featured in the book Speciality rices of the world by Food and Agriculture Organization of the United Nations.
Ancient grains is a marketing term used to describe a category of grains and pseudocereals that are purported to have been minimally changed by selective breeding over recent millennia, as opposed to more widespread cereals such as corn, rice and modern varieties of wheat, which are the product of thousands of years of selective breeding. Ancient grains are often marketed as being more nutritious than modern grains, though their health benefits over modern varieties have been disputed by some nutritionists.
Gandhakasala rice is a variety of rice cultivated by the farmers in Wayanad District in Kerala. This is a scented variety of rice grown mostly by the members of the tribal communities of in Panamaram, Sultan Bathery, and Mananthavady areas in Wayanad. As of 2010, gandhkasala is cultivated in an area of 327 hectares and jeerakasala in 22 hectares.
Paw san hmwe is a high-grade variety of aromatic rice grown in Myanmar. Paw hsan hmwe is known for its good cooking quality, fragrant aroma, texture, good milling recovery, and substantial grain elongation during the cooking process. The medium-length grains of this rice variety can elongate up to three times in length while cooking. Paw hsan hmwe has intermediate amylose content, higher than jasmine rice, contributing to its hardness quality in line with Burmese consumer preferences. Myanmar's Paw San rice is one of the world's most recognized high quality rice, it was awarded the world's best rice at the Rice Trader's World Rice Conference in 2011. Paw San rice has a similar aroma, grain quality and eating quality to the reputable aromatic rice varieties of the world, namely Basmati of India and Pakistan and Jasmine of Thailand. It has a strong aroma similar to Jasmine rice and
The history of rice cultivation is an interdisciplinary subject that studies archaeological and documentary evidence to explain how rice was first domesticated and cultivated by humans, the spread of cultivation to different regions of the planet, and the technological changes that have impacted cultivation over time.
Arroz de fríjol cabecita negra is a rice-based dish from the Caribbean Coast of Colombia that utilizes black-eyed peas as the legume, differing from other rice dishes that are usually prepared with different legumes such as beans, peas, lentils, and Pigeon peas.
