"Echinochloa crus-galli is a ANNUAL growing to 1.2 m (4ft) by 0.2 m (0ft 8in).
It is hardy to zone (UK) 6. It is in flower from Jul to September, and the seeds ripen from Aug to October. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Wind.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils and prefers well-drained soil. Suitable pH: acid, neutral and basic (alkaline) soils and can grow in very alkaline soils. It cannot grow in the shade. It prefers moist soil. The plant can tolerates strong winds but not maritime exposure." [PFAF]
"General: Annual grass from fibrous roots; stems pith-filled or hollow, decumbent to erect, the nodes smooth, (30) 60-160 cm tall.
Stem: spreading, decumbent or stiffly erect, 3–20 dm." [IFBC-E-flora]
"Habitat / Range
Moist to dry ditches, disturbed sites, clearings and fields in the lowland, steppe and montane zones; common in S BC; introduced from Eurasia." [IFBC-E-flora] "Moist clearings, wet ditches, cultivated fields,
bamyards; common at low elevations, mostly in settled areas." [PCBC2004]
Origin Status: Exotic [E-flora]
"This grass has been reported to accumulate levels of nitrate in its tissues high enough to be toxic to farm animals[269]. This problem is most likely to occur when plants are fed with inorganic fertilizers [K]." [PFAF]
"Earlier in this century. enterprising American seedsmen (hucksters) advertised a cultivated variety of barnyard-grass as 'billion dollar grass,' recom- mended for forage as green feed. silage or hay. However. it proved too succulent for hay and its use waned with the introduction of other productive crops of higher value." [PCBC2004]

Propagation
"Seed - sow early spring in a greenhouse and only just cover the seed. When they are large enough to handle, prick the seedlings out into individual pots and plant them out into their permanent positions in early summer. A sowing in situ in late spring might also succeed but is unlikely to ripen a crop of seed if the summer is cool and wet." [PFAF]
Cultivation
"An easily grown plant, it is adapted to nearly all types of wet places, and is often a common weed in paddy fields, roadsides, cultivated areas, and fallow fields[269]. It succeeds on a variety of wet sites such as ditches, low areas in fertile croplands and wet wastes, often growing in water[269]. It succeeds in cool regions, but is better adapted to areas where the average annual temperature is 14-16°C[269]. Tolerant of most soil types, including saline conditions, plants are not restricted by soil pH[269]. Prefers a rich moist soil[85] but succeeds in ordinary garden soil[1]. The sub-species E. crus-galli zelayensis (HBK)Hitchc. is often found growing wild in alkaline soils[236]. The plant is reported to tolerate an annual precipitation in the range of 31 to 250cm, an annual temperature range of 5.7 to 27.8°C and a pH in the range of 4.8 to 8.2[269]. Barnyard millet is sometimes cultivated for its edible seed in India[171]. It has a relatively long growing season and does not always ripen its seed in Britain, though it should do better in the eastern half of the country[K]. The plant is considered to be a very serious weed of many cultivated crops[269]." [PFAF]
The dried powder of M. sativa has been shown to inhibit the germination and growth of Echinochloa crus-galli Wight (Gwon & Kim, 2006). [MedSativa]
"Members of three antimicrobial peptide families and two protease inhibitor families were found to be localized in barnyard grass seeds. Their biological activity concerning to Gram-Positive and Gram-Negative phy- topathogenic bacteria, as well as oomycete Phytophthora infestans, has been investigated. Diversity of barnyard grass defense peptides is a significant factor that provides a resistance of E. crusgalli seeds to germination and latent phases." [Rogozhin,2012]
Crop weed: "Barnyard grass [Echinochloa crusgalli (L.) Beauv.], an annual grass, has been reported to cause problems in at least 61 countries and in at least 36 different crops (Holm et al., 1991). It is a major weed in paddy fields as it competes with rice (Oryza sativa L.) and causes reduction in rice yield. Competition from 25 barnyard grass plants/m2 can cause 50% reduction in rice yield (Chin, 2001)." [Xuan,2006]
"The same principle was exploited by Scheepens (1987) to aid control of barnyard grass (Echinochloa crus-galli) by Cochliobolus Iunatus. Here, the synergistic effect between fungus and herbicide was achieved with a low dose of the chemical (2.5 mg/m2). Gohbara and Yamagu- chi (1993) showed that the herbicide pyrazo-sulfuron-ethyl synergizes the control of barnyard grass by Dreschlera monoceras at the much lower dose of 0.044 mg/m2." [Burges FMB]
"Dahlquist et al. (2007) observed that seeds of all tested weed species were killed at 50°C and above, though Portulaca oleracea L., Amaranthus albus L., Echinochloa crus-galli L., and Solanum nigrum L. were not affected by heating up to 46°C, 42°C, and 39°C." [Lichtfouse SAR 3]
"The dried powder of M. sativa[Medicago sativa] has been shown to inhibit the germination and growth of Echinochloa crus-galli Wight (Gwon & Kim, 2006)." [Bora,2011]
"Ergosterol peroxide was obtained for the first time from Oryza sativa in 2006. This is the first report of potential allelopathic activity of steroids on weeds based on their phytotoxicity on barnyardgrass (Echinochloa crus-galli) as target species.363" [Liu et al.,2013]
"Rice, another main crop, that is mainly cultivated in north of Iran. There are many research programmes regarding allelopathy of rice in this country. Asghari et al. (2006) conducted several studies on rice allelopathy and found that seedling growth of barnyard grass (Echinochloa crus-galli) was very sensitive to rice tissues. Hull extracts of 46 rice cultivars at various concentrations had inhibitory effect on barnyard grass seedling growth" [Cheema Alleleopathy]
"Sorghum (Sorghum bicolor L.) also contains a number of allelochemicals that possess phytotoxic effect against weeds. Previously, Panasiuk et al. (1986) revealed that weeds such as Echinochloa crus-galli (L.) Beauv., Amaranthus retroflexus L. and Rumex acetosella L., when interplanted with sorghum showed a significant reduction in their germination, growth and dry weight." [Dighton IIS]
"Allelopathic potential of plants is affected by many factors. An increase of allelopathic effects was observed by the water deficit, high temperature, high irradi- ance, pathogen, insect and herbivore damages, or nutrients deficiency (Hura et al. 2006). In other case, the concentrations of the allelochemicals released from the allelopathic rice seedlings in soil increased dramatically (3-fold higher) when they were surrounded with barnyard grass (Echinochloa crus-galli (L.) Beauv.) (Kong et al. 2006)." [Lichtfouse SAR 3]
"Kava showed a strong inhibition on growth of barnyardgrass (Echinochloa crus-galli)..." [EMNMPV.11]
"There are many experiments which showed allelopathic effect of different plants, e.g., alkaloid content of mesquite (Prosopis juliflora) leaves showed allelopathic activity against root growth of lettuce (Lactuca sativa) and barnyard grass (Echinochloa crus-galli) [36]." [Ramawat NP]
In soil co-contaminated by cadmium, lead and 2,4,6-trinitrotoluene (TNT), barnyard grass (Echinochloa crusgalli), sunflower (Helianthus annuus), Indian mallow (Abutilon avicennae) and Indian joinivetch (Aeschynomene indica) likely and rapidly remove TNT (Lee et al., 2007).[Golubev HP]
Similarly, Lee et al. (2007) worked on four plant species i.e. barnyard grass (Echinochloa crusgalli), sunflower (Helianthus annuus), Indian mallow (Abutilon avicennae) and Indian jointvetch (Aeschynomene indica), for the remediation of TNT contaminated soil and observed that all the four species had a high potential to remove TNT and its metabolites, regardless of whether the culture was grown single or mixed. The concentrations of TNT and its metabolites, 2-amino-4,6-dinitrotoluene (2-ADNT)) and 4-amino-2,6 dinitrotoluene (4-ADNT) were found very high in H. annuus, A. indica and A. avicennae except Echinochloa crusgalli.[Singh BRER]
They examined the effect of oil addition on the growth and development of common chickweed (Stellaria media L.), couch grass (Elytrigia repens L.), and barnyard grass (Echinochloa crusgalli L.) at both laboratory and field scales. Addition of oil prolonged the vegetative period, but the plant height in polluted soil did not reach the control value. In polluted (0.5–4%) soil, a decrease in the yield of the above-ground biomass was observed. Under the effect of oil, the protein content of couch grass hay decreased twofold. The herbage of all three grasses contained 3,4-benzo(a)pyrene 10- to 15-fold in excess of the background maximum allowable values, ruling out the possibility that these grasses could be used as fodder crops.[Willey PMR]
"A similar study on Echinochloa crus-galli was done and showed that root exudates allow increased accumulation of Pb, Cd, and Cu. A much higher concentration of metals was absorbed by the plant in the presence of root exudates as compared with those without them. Hence they serve as potent natural chelators (Kim et al., 2010). Natural chelators have the ability to increase mobility of metals by making them uncharged. They are synthesized by the plant and are more promising than synthetic chelators that pose threats to soil." [ghori,2016]
"Since diversity of plant and bacteria community are mostly affected in polluted environment (Travis et al. 2008), it is necessary during phytoremediation, to choose plants with known capabilities of degrading or accumulating contaminants, that can also complement each other rather than those that compete with each other. For example, when Echinochloa crus-galli, Helianthus annuus and Abutilon avicennae and Aeschynomene indica were used as mixed and mono- cultures in a 2,4,6- trinitrotoluene, Cd and Pb phytoremediation trial, trinitrotoluene was removed irrespective of mixed or monocultures. Moreover, more Cd was removed by mono- culture than mixed culture and there appeared to be competition as slower growth rate was reported in the mixed culture (Lee et al. 2007)." [HMR,Gupta]
"Chen et al. (2005) found that mycorrhizae enhanced biomass and root/shoot ratios of Kummerowia striata, Ixeris denticulata, and Echinochloa crus-galli. They suggested that under an elevated Pb condition, mycorrhizae could promote plant growth by increasing Pb uptake and mitigating Pb toxicity by sequestrating more Pb in roots." [Phytorem1]
The continuous use of propanil (Herbicide) in Arkansas rice production has resulted in the development of a propanil-resistant barnyardgrass biotype, capable of metabolizing the herbicide by arylacylamidase activity (80–82). [PlantTox]
"Oil and oil products are major technogenic pollutants in the Republic of Bashkortostan, eastern Russia. For over 7 yr, scientists at Bashkir State University have been studying the effect of oil-contaminated soils on agricultural plants (4,5). They examined the effect of oil addition on the growth and development of common chickweed (Stellaria media L.), couch grass (Elytrigia repens L.), and barnyard grass (Echinochloa crusgalli L.) at both laboratory and field scales. Addition of oil prolonged the vegetative period, but the plant height in polluted soil did not reach the control value. In polluted (0.5–4%) soil, a decrease in the yield of the above-ground biomass was observed. Under the effect of oil, the protein content of couch grass hay decreased twofold. The herbage of all three grasses contained 3,4-benzo(a)pyrene 10- to 15-fold in excess of the background maximum allowable values, ruling out the possibility that these grasses could be used as fodder crops. However, because couch grass is able to form turf, it can be recommended for use on oil-contaminated lands with a view to recovering soil fertility (6)." [Willey PMR]
