Cyperus iria (also known as rice flat sedge and rice flatsedge) is a smooth, tufted sedge found worldwide. The roots are yellowish-red and fibrous. [2] [3] The plant often grows in rice paddies, where it is considered to be a weed. [4]
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus Carex with over 2,000 species.
A raceme or racemoid is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers along its axis. In botany, an axis means a shoot, in this case one bearing the flowers. In indeterminate inflorescence-like racemes, the oldest flowers are borne towards the base and new flowers are produced as the shoot grows, with no predetermined growth limit. A plant that flowers on a showy raceme may have this reflected in its scientific name, e.g. Cimicifuga racemosa. A compound raceme, also called a panicle, has a branching main axis. Examples of racemes occur on mustard and radish plants.
Cyperus is a large genus of about 700 species of sedges, distributed throughout all continents in both tropical and temperate regions.
Cyperus esculentus is a crop of the sedge family widespread across much of the world. It is found in most of the Eastern Hemisphere, including Southern Europe, Africa and Madagascar, as well as the Middle East and the Indian subcontinent. C. esculentus is cultivated for its edible tubers, called earth almonds or tiger nuts, as a snack food and for the preparation of horchata de chufa, a sweet, milk-like beverage.
Pelopidas mathias, the dark small-branded swift, small branded swift, lesser millet skipper or black branded swift, is a butterfly belonging to the family Hesperiidae. It is found throughout much of south, southeast and East Asia, and as far as the Philippines. It is also present in tropical Africa and Arabia.
Ageratum conyzoides is native to Tropical America, especially Brazil, and is an invasive weed in many other regions. It is an herb that is 0.5–1 m. high, with ovate leaves 2–6 cm long, and flowers are white to mauve.
Cyperus bulbosus is a species of sedge found across Africa, the Middle East, Indian subcontinent, Southeast Asia, and Australia. In Australia, it is commonly called Nalgoo or (Australian) bush onion or "wild onion", but is not related to the onion or other Alliaceae. It is a component of Australian bushfood, but is considered an agricultural weed in other areas.
Thalipeeth is a savoury multi-grain flatbread popular in Western India, particularly Maharashtra. The flour for thalipeeth, called bhajanee, is prepared from roasted grains, legumes and spices. The ingredients include grains such as rice, wheat, bajra, and jowar), legumes such as chana, and urad) and spices, most commonly coriander and cumin seeds. When preparing the dough, other ingredients such as onion, fresh coriander, other vegetables and spices are added. Thalipeeth is usually served with butter, ghee, or yogurt. The dish is popular in Maharashtra and north Karnataka, and it is also made with regional variations in Goa.
Ambemohar is a fragrant rice variant grown in the foothills of the Western ghats region of the state of Maharashtra in India.
Cyperus eragrostis is a species of sedge known by several common names, including tall flatsedge, nutgrass, tall nutgrass, umbrella sedge, chufa, Earth almond, zula nuts, edible galingale and pale galingale.
The San Chay people live in Tuyên Quang Province of the Northeast region of Vietnam, as well as some nearby provinces. The SanChay language is a form of Tai-Kadai language. Their population was 201,398 in 2019.
Cyperus difformis is a species of sedge known by several common names, including variable flatsedge, smallflower umbrella-sedge and rice sedge. This plant is native to southern Europe, most of Africa and Asia, and Australia, and it is naturalized in other areas of the world, including large parts of the Americas.
Myinmu is a river town in the south-east of the Sagaing Division in Burma. The town has a rich history linked to World War II during the Burma Campaign against the Japanese, in 1944. It was also under the control of the Portuguese Missionaries in the 19th century. One of the first agricultural cooperatives was established here in 1905.
Aromatic rice is one of the major types of rice. It is a medium- to long-grained rice. It is known for its nutty aroma and taste, which is caused by the chemical compound 2-acetyl-1-pyrroline. Varieties of aromatic rice include Ambemohar, Basmati, Jasmine, Sona Masuri, Texmati, Tulaipanji, Tulshimala, Wehani, Kalijira, Chinigura, Gobindobhog and wild Pecan rice. When cooked, the grains have a light and fluffy texture except for Gobindobhog rice which is sticky in texture.
Myinmu Township is a township in the southeast of the Sagaing Division in Burma (Myanmar), west of Mandalay. The principal town is Myinmu which lies on the northern bank of the Irrawaddy River. History of Myinmu is closely linked to the World War II against the Japanese Army when British General Sir Douglas Gracey occupied the town after crossing the Irrawaddy River.
Agriculture in Sierra Leone is a significant part of the economy of Sierra Leone, with it accounting for 58 percent national Gross Domestic Product (GDP) in 2007. Two-thirds of the population of Sierra Leone are involved in subsistence agriculture.
Deepwater rice are varieties of rice grown in flooded conditions with water more than 50 cm (20 in) deep for at least a month. More than 100 million people in Southeast Asia including Northeastern India rely on deepwater rice for their sustenance. Two adaptations permit the rice to thrive in deeper water, floating rice and traditional talls. Traditional talls are varieties that are grown at water depths between 50 and 100 cm and have developed to be taller and have longer leaves than standard rice. Floating rice grows in water deeper than 100 cm through advanced elongation ability. This means when a field where rice is growing floods, accelerated growth in the internodal of the stem allows the plant to keep some of its foliage on top of the water. The O. s. indica cultivar is the main type of deepwater rice, although varieties of O. s. japonica have been found in Burma and Assam Plains.
Urena lobata, commonly known as Caesarweed or Congo jute, is a tender perennial, variable, erect, ascendant shrub or subshrub measuring up to 0.5 meters (1.6 ft) to 2.5 meters (8.2 ft) tall. The stems are covered with minute, star-like hairs and often tinged purple. Considered a weed, it is widely distributed in the tropics, including in Brazil and Southeast Asia.
Cyperus longus is a species of sedge known by the common names of sweet cyperus and water rush in Africa, or galingale in Britain. It is a tall plant, growing up to a metre in height, with creeping rhizomes and erect, triangular stems, each terminating in an inflorescence. The species grows in shallow water or on damp ground, such as at pond edges.
Dilbagh Singh Athwal was an Indian geneticist, plant breeder and agriculturist, known to have conducted pioneering research in plant breeding. He was a professor and the Head of the Department of Plant Breeding at Punjab Agricultural University and an associate of Norman Borlaug, the renowned biologist and Nobel Laureate, with whom he has collaborated for the introduction of high-yielding dwarf varieties of wheat.
