Echinochloa crus-galli is a type of wild grass originating from tropical Asia that was formerly classified as a type of panicum grass. It is commonly known as cockspur (or cockspur grass), barnyard millet, Japanese millet, water grass, common barnyard grass, or simply "barnyard grass" (which may refer to any species of Echinochloa or the genus as a whole however). This plant can grow to 60" (1.5 m) in height and has long, flat leaves which are often purplish at the base. Most stems are upright, but some will spread out over the ground. Stems are flattened at the base. The seed heads are a distinctive feature, often purplish, with large millet-like seeds in crowded spikelets.
Considered one of the world's worst weeds, it reduces crop yields and causes forage crops to fail by removing up to 80% of the available soil nitrogen. It acts as a host for several mosaic virus diseases. [3] Heavy infestations can interfere with mechanical harvesting.
Individual plants can produce up to 40,000 seeds per year. Water, birds, insects, machinery, and animal feet disperse it, but contaminated seed is probably the most common dispersal method.
Polymorphous coarse, tufted annual, tall and often weedy; culms erect to decumbent, 0.8–1.5 m tall, rather thick, branching at base.
Leaves flat, glabrous, elongate, 30–50 cm long, 1–2 cm broad, scabrous, slightly thickened at margin; ligules absent; sheaths smooth, lower ones often reddish; panicle 8–30 cm long, green or purple, exerted, somewhat nodding, densely branched, the branches to 5 cm long, erect or ascending sessile;
Spikelets 3–4 mm long, densely arranged on branches, ovoid, often long-awned, pale green to dull purple, short-bristly along veins; racemes spreading, ascending or appressed, the lower somewhat distant, as much as 10 cm long, sometimes branched; glumes and lower lemma minutely hairy on surface with longer more rigid hairs on veins; first glume about two-fifths as long as spikelet, deltoid, the second as long as the spikelet, short-awned; sterile lemma membranous, with a straight scabrous awn, 2–4 cm long or awnless; fertile lemma ovate-elliptic, acute, pale yellow, lustrous, smooth, 3–3.5 mm long. Fl.
Aug.–Oct.; seed maturing Sept.–Oct., up to 40,000/plant. Var. crus-galli has long, somewhat spreading papillose cilia at the summits of the internodes and bases of the branches in the inflorescence and short, very thick papillose cilia along the lateral nerves of the 2nd glume, sterile lemma, and somewhat spreading spikes", and sterile lemmas with awns 0–10 mm long.

Barnyard grass commonly occurs throughout tropical Asia and Africa in fields and along roadsides, ditches, along railway lines, and in disturbed areas such as gravel pits and dumps. It also invades riverbanks and the shores of lakes and ponds. It occurs in all agricultural regions. This species is considered an invasive species in North America where it occurs throughout the continental United States. It is also found in southern Canada from British Columbia east to Newfoundland. [5] It was first spotted in the Great Lakes region in 1843. [6]
Ranging from Boreal Moist to Wet through Tropical Very Dry to Moist forest life zones. Adapted to nearly all types of wet places, this grass is often a common weed in paddy fields, roadsides, cultivated areas, and fallow fields. It grows on variety of wet sites such as ditches, low areas in fertile croplands and wet wastes, often growing in water. Succeeds in cool regions, but better adapted to areas where average annual temperature is 14–16 °C. Not restricted by soil pH. [3]
E. crus-galli was domesticated in southern Hokkaido 4,500 years ago. [1]
A warm-season grass used as cattle fodder and is sometimes cultivated for this purpose. It is also suited for silage, but not for hay. It is fed green to animals and provides fodder throughout the year; hay made from this plant can be kept up to 6 years. This grass is also used for reclamation of saline and alkaline areas, especially in Egypt.
This grass is readily eaten by wild animals: rabbits, deer, waterfowls, etc. [3]
The grain of some varieties is eaten by humans in times of scarcity and sometimes used for adulterating fennel. [7] The roots are boiled to cure indigestion in the Philippines. The young shoots are eaten as a vegetable. The plant extract is used in diseases of the spleen. Young shoots are eaten as a vegetable in Java. Reported to be preventative and tonic, barnyard grass is a folk remedy in India for carbuncles, haemorrhages, sores, spleen trouble, cancer and wounds.
In the Hisar district of the Indian state of Haryana the seeds of this grass are commonly eaten with cultivated rice grains to make rice pudding or khir on Hindu fast days.
Barnyard grass was one of the five most cultivated crops during Joseon Dynasty in Korea. Rural Development Administration of South Korean government discovered barnyard grass effectively lowers blood sugar and cholesterol when consumed, according to Yonhap. [8]
Japanese barnyard millet (Echinochloa esculenta syn. E. cg. var. utilis), [1] a domesticated form of E. crus-galli, is cultivated on a small scale in Japan, Korea and China. It underwent selection for larger grain size over a span of one or two millennia in Japan. [1]
This grass is subject to the brown spot disease caused by Bipolaris oryzae , a fungal infection.
The following Punjabi dialect forms are recorded in Punjab for this grass:
Millets are a highly varied group of small-seeded grasses, widely grown around the world as cereal crops or grains for fodder and human food. Most species generally referred to as millets belong to the tribe Paniceae, but some millets also belong to various other taxa.
Panicum miliaceum is a grain crop with many common names, including proso millet, broomcorn millet, common millet, hog millet, Kashfi millet, red millet, and white millet. Archaeobotanical evidence suggests millet was first domesticated about 10,000 BP in Northern China. Major cultivated areas include Northern China, Himachal Pradesh of India, Nepal, Russia, Ukraine, Belarus, the Middle East, Turkey, Romania, and the Great Plains states of the United States. About 500,000 acres are grown each year. The crop is notable both for its extremely short lifecycle, with some varieties producing grain only 60 days after planting, and its low water requirements, producing grain more efficiently per unit of moisture than any other grain species tested. The name "proso millet" comes from the pan-Slavic general and generic name for millet.
Paspalum is a genus of plants in the grass family.
Panicum (panicgrass) is a large genus of about 450 species of Poaceae grasses native throughout the tropical regions of the world, with a few species extending into the northern temperate zone. They are often large, annual or perennial grasses, growing to 1–3 m (3–10 ft) tall.
Foxtail millet, scientific name Setaria italica, is an annual grass grown for human food. It is the second-most widely planted species of millet, and the most grown millet species in Asia. The oldest evidence of foxtail millet cultivation was found along the ancient course of the Yellow River in Cishan, China, carbon dated to be from around 8,000 years before present. Foxtail millet has also been grown in India since antiquity.
Echinochloa frumentacea is a species of Echinochloa. Both Echinochloa frumentacea and E. esculenta are called Japanese millet. This millet is widely grown as a cereal in India, Pakistan, and Nepal. Its wild ancestor is the tropical grass Echinochloa colona, but the exact date or region of domestication is uncertain. It is cultivated on marginal lands where rice and other crops will not grow well. The grains are cooked in water, like rice, or boiled with milk and sugar. Sometimes it is fermented to make beer. While also being part of staple diet for some communities in India, these seeds are, in particular, eaten during religious fasting. For this reason, these seeds are commonly also referred to as "vrat ke chawal" in Hindi. Other common names to identify these seeds include oodalu (ಊದಲು) in Kannada, Shyamak (শ্যামাক) or Shyama Chal in Bangla, jhangora in the Garhwal Hills, bhagar (भगर) in Marathi-speaking areas, samo or morio seeds in Gujarati, or kuthiraivaali (குதிரைவாளி) in Tamil.
Echinochloa esculenta is a species of grass in the family Poaceae. It is referred to by the common names Japanese barnyard millet or Japanese millet, is a species of Echinochloa that is cultivated on a small scale in India, Japan, China and Korea, both as a food and for animal fodder. It is grown in areas where the land is unsuitable or the climate too cool for paddy rice cultivation. However, the development of rice varieties that can withstand cold has led to a sharp decline in the cultivation of Japanese barnyard millet, in favor of rice. The earliest records of the domesticated form date to 2000 BC from the Jōmon period of Japan.
Echinochloa colonum, commonly known as jungle rice, wild rice, deccan grass, jharua or awnless barnyard grass, is a type of wild grass originating from tropical Asia. It was formerly classified as a species of Panicum. It is the wild ancestor of the cultivated cereal crop Echinochloa frumentacea, sawa millet. Some taxonomists treat the two taxa as one species, in which case the domesticated forms may also be referred to as E. colonum.
Echinochloa is a very widespread genus of plants in the grass family and tribe Paniceae. Some of the species are known by the common names barnyard grass or cockspur grass.
Panicum antidotale Retz. is a tall, coarse, woody perennial grass throughout the Himalaya and the Upper Gangetic Plain and specifically in various regions of the Indian state of Punjab and the Pakistan province of Punjab and the neighbouring areas of these regions. The plant has strong spreading rhizomes.
Panicum decompositum, known by the common names native millet, native panic, Australian millet, papa grass, and umbrella grass, is a species of perennial grass native to the inland of Australia. It occurs in every mainland state. The seeds can be cultivated to produce flour typically used in Aboriginal bushfood. The species is also considered to have relatively high palatability by livestock, making it suitable for grazing pastures.
Paspalum scrobiculatum, commonly called Kodo millet or Koda millet, is an annual grain that is grown primarily in Nepal and also in India, Philippines, Indonesia, Vietnam, Thailand, and in West Africa from where it originated. It is grown as a minor crop in most of these areas, with the exception of the Deccan plateau in India where it is grown as a major food source. It is a very hardy crop that is drought tolerant and can survive on marginal soils where other crops may not survive, and can supply 450–900 kg of grain per hectare. Kodo millet has large potential to provide nourishing food to subsistence farmers in Africa and elsewhere.
Echinochloa crus-pavonis is a species of grass known by the common name gulf cockspur grass. It is native to much of the Americas, Africa, and part of Asia, and it is known throughout the world as an introduced species. It is an annual grass often exceeding 1.5 meters in maximum height. The inflorescence is divided into several branches coated in green spikelets.
Brachiaria, or signalgrass, is a genus of plants in the grass family native to tropical and subtropical regions of Asia, Africa, Australia, southern Europe, the Americas, and various islands. There are over 100 species.
Panicum hirticaule is a species of grass known by the common names Mexican panicgrass and roughstalked witchgrass. It is also known as the Sonoran millet, and is cultivated as a cereal crop in the American Southwest.
