Botanical Name : Chenopodium quinoa
Family: Amaranthaceae
Subfamily: Chenopodioideae
Genus: Chenopodium
Species: C. quinoa
Kingdom: Plantae
Order: Caryophyllales
Common Spanish Name :Quinua, from Quechua kinwa
Habitat :The original habitat is obscure, the plant probably arose through cultivation.
Quinoa originated in the Andean region of South America, where it has been an important food for 6,000 years. Its name is the Spanish spelling of the Quechua name. Quinoa is generally undemanding and altitude-hardy, so it can be easily cultivated in the Andes up to about 4,000 meters. Even so, it grows best in well-drained soils and requires a relatively long growing season. In eastern North America, it is susceptible to a leaf miner that may reduce crop success; this leaf miner also affects the common weed and close relative Chenopodium album, but C. album is much more resistant.
Similar Chenopodium species, such as pitseed goosefoot (Chenopodium berlandieri) and fat hen (Chenopodium album), were grown and domesticated in North America as part of the Eastern Agricultural Complex before maize agriculture became popular. Fat hen, which has a widespread distribution in the Northern Hemisphere, produces edible seeds and greens much like quinoa, but in lower quantities.
ANNUAL growing to 1.5 m (5ft) by 0.3 m (1ft in).
It is not frost tender. It is in flower from Jul to August, and the seeds ripen from Aug to September. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Wind, self.The plant is self-fertile.
The plant prefers light (sandy), medium (loamy) and heavy (clay) soils and requires well-drained soil.The plant prefers acid, neutral and basic (alkaline) soils. and can grow in very alkaline and saline soils.
It cannot grow in the shade.It requires moist soil and can tolerate drought.The plant can tolerates strong winds but not maritime exposure.
Quinoa is a species of goosefoot (Chenopodium), is a grain-like crop grown primarily for its edible seeds. It is a pseudocereal rather than a true cereal, or grain, as it is not a member of the grass family. As a chenopod, quinoa is closely related to species such as beets, spinach, and tumbleweeds. Its leaves are also eaten as a leaf vegetable, much like amaranth, but the commercial availability of quinoa greens is currently limited.
Chenopodium quinoa (and a related species from Mexico, Chenopodium nuttalliae) is most familiar as a fully domesticated plant, but it was believed to have been domesticated in the Andes from wild populations of Chenopodium quinoa. There are non-cultivated quinoa plants (Chenopodium quinoa var. melanospermum) which grow in the same area where it is cultivated; those are probably related to quinoa’s wild predecessors, but could instead be descendants of cultivated plants.
History & Culture:
The Incas, who held the crop to be sacred, referred to quinoa as chisaya mama or mother of all grains, and it was the Inca emperor who would traditionally sow the first seeds of the season using ‘golden implements’. During the European conquest of South America quinoa was scorned by the Spanish colonists as food for Indians, and even actively suppressed, due to its status within indigenous non-Christian ceremonies. In fact, the conquistadors forbade quinoa cultivation for a time and the Incas were forced to grow corn instead.
Cultivation:
An easily grown plant, it requires a rich moist well-drained soil and a warm position if it is to do really well, but it also succeeds in less than optimum conditions. Tolerates a pH range from 6 to 8.5 and moderate soil salinity. Plants are quite wind resistant. Plants are drought tolerant once they are established. Plants tolerate light frosts at any stage in their development except when flowering. Quinoa (pronounced keen-wa) is commonly cultivated as a grain crop in Chile and Peru. This plant is receiving considerable attention world-wide as a trouble-free easily grown seed crop for warm temperate and tropical zones. It has the potential to outcrop cereals on light land in Britain. There are a great many named varieties. The plant is day-length sensitive and many varieties fail to flower properly away from equatorial regions, however those varieties coming from the south of its range in Chile are more likely to do well in Britain. Different cultivars take from 90 – 220 days from seed sowing to harvest. Yields as high as 5 tonnes per hectare have been recorded in the Andes, which compares favourably with wheat in that area[196]. Young plants look remarkably like the common garden weed fat hen (Chenopodium album). Be careful not to weed the seedlings out in error. The seed is not attacked by birds because it has a coating of bitter tasting saponins. These saponins are very easily removed by soaking the seed overnight and then thoroughly rinsing it until there is no sign of any soapiness in the water. The seed itself is very easy to harvest by hand on a small scale and is usually ripe in August. Cut down the plants when the first ripe seeds are falling easily from the flower head, lay out the stems on a sheet in a warm dry position for a few days and then simply beat the stems against a wall or some other surface, the seed will fall out easily if it is fully ripe and then merely requires winnowing to get rid of the chaff.
Propagation :
Seed – sow April in situ. The seed can either be sown broadcast or in rows about 25cm apart, thinning the plants to about every 10cm. Germination is rapid, even in fairly dry conditions. Be careful not to weed out the seedlings because they look very similar to some common garden weeds[
Edible Uses
Edible Parts: Leaves; Seed.
Seed – cooked. A pleasant mild flavour, the seed can absorb the flavour of other foods that are cooked with it and so it can be used in a wide variety of ways. It should be thoroughly soaked and rinsed to remove a coating of saponins on the seed surface. The seed can be used in all the ways that rice is used, as a savoury or sweet dish. It can also be ground into a powder and used as a porridge. The seed can also be sprouted and used in salads though many people find the sprouted seed unpleasant. The seed contains a very high quality protein that is rich in the amino acids lysine, methionine and cystine, it has the same biological value as milk. The seed contains about 38% carbohydrate, 19% protein, 5% fat, 5% sugar. Leaves – raw or cooked. The young leaves are cooked like spinach. It is best not to eat large quantities of the raw leaves, see the notes above on toxicity.
Nutritional Value :
Quinoa was of great nutritional importance in pre-Columbian Andean civilizations, being secondary only to the potato, and was followed in importance by maize. In contemporary times, this crop has become highly appreciated for its nutritional value, as its protein content is very high (12%–18%). Unlike wheat or rice (which are low in lysine), and like oats, quinoa contains a balanced set of essential amino acids for humans, making it an unusually complete protein source among plant foods. It is a good source of dietary fiber and phosphorus and is high in magnesium and iron. Quinoa is gluten-free and considered easy to digest. Because of all these characteristics, quinoa is being considered a possible crop in NASA’s Controlled Ecological Life Support System for long-duration manned spaceflights

Chenopodium quinoa as World’s most Healthy Food :
Preparation:
Quinoa has a light, fluffy texture when cooked, and its mild, slightly nutty flavor makes it an alternative to white rice or couscous.
The first step in preparing quinoa is to remove the saponins, a process that requires soaking the grain in water for a few hours, then changing the water and resoaking, or rinsing it in ample running water either in a fine strainer or in cheesecloth. Removal of the saponin helps with digestion; the soapy nature of the compound makes it act as a laxative. Most boxed quinoa has been pre-rinsed for convenience.
A common cooking method is to treat quinoa much like rice, bringing two cups of water to a boil with one cup of grain, covering at a low simmer and cooking for 14–18 minutes or until the germ separates from the seed. The cooked germ looks like a tiny curl and should have a slight bite to it (like al dente pasta). As an alternative, one can use a rice cooker to prepare quinoa, treating it just like white rice (for both cooking cycle and water amounts).
Vegetables and seasonings can also be added to make a wide range of dishes. Chicken or vegetable stock can be substituted for water during cooking, adding flavor. It is also suited to vegetable pilafs, complementing bitter greens like kale.
Quinoa can serve as a high-protein breakfast food mixed with honey, almonds, or berries; it is also sold as a dry product, much like corn flakes. Quinoa flour can be used in wheat-based and gluten-free baking.
Quinoa may be germinated in its raw form to boost its nutritional value. Germination activates its natural enzymes and multiplies its vitamin content.[6] In fact, quinoa has a notably short germination period: Only 2–4 hours resting in a glass of clean water is enough to make it sprout and release gases, as opposed to, e.g., 12 hours overnight with wheat.[citation needed] This process, besides its nutritional enhancements, softens the grains, making them suitable to be added to salads and other cold foods
Name of crops:
This crop is known as quinoa in English and, according to Merriam-Webster, the primary pronunciation is with two syllables with the accent on the first (English pronunciation:KEEN-wah). It may also be pronounced with three syllables, with the stress on either the first syllable or on the second . In Spanish, the spelling and pronunciation vary by region. The accent may be on the first syllable, in which case it is usually spelled quinua [kinwa], with quínoa [kinoa] being a variant; or on the second syllable: [ki?noa]), in which case it is spelled quinoa. The name derives from the Quechua kinwa, pronounced in the standard dialect [kinwa]. There are multiple other native names in South America:

Quechua: ayara, kiuna, kuchikinwa, achita, kinua, kinoa, chisaya mama
Aymara: supha, jopa, jupha, juira, ära, qallapi, vocali
Chibchan: Suba, pasca
Mapudungun: dawe, sawe
Other Uses
Dye; Repellent; Soap.
Gold/green dyes can be obtained from the whole plant. Saponins on the seed can be used as a bird and insect deterrent by spraying them on growing plants. The saponins are obtained by saving the soak-water used when preparing the seed for eating. The spray remains effective for a few weeks or until washed off by rain.
Known Hazards : The leaves and seeds of all members of this genus are more or less edible. However, many of the species in this genus contain saponins, though usually in quantities too small to do any harm. Although toxic, saponins are poorly absorbed by the body and most pass straight through without any problem. They are also broken down to a large extent in the cooking process. Saponins are found in many foods, such as some beans. Saponins are much more toxic to some creatures, such as fish, and hunting tribes have traditionally put large quantities of them in streams, lakes etc in order to stupefy or kill the fish[K]. The plants also contain some oxalic acid, which in large quantities can lock up some of the nutrients in the food. However, even considering this, they are very nutritious vegetables in reasonable quantities. Cooking the plants will reduce their content of oxalic acid. People with a tendency to rheumatism, arthritis, gout, kidney stones or hyperacidity should take especial caution if including this plant in their diet since it can aggravate their condition.
