Oats, barley, and some food products made from cereal grains

Cereals are grasses (members of the monocot family Poaceae, also known as Gramineae)^[1] cultivated for the edible components of their grain (botanically, a type of fruit called a caryopsis), composed of the endosperm, germ, and bran. Cereal grains are grown in greater quantities and provide more food energy worldwide than any other type of crop^{[citation needed]}; they are therefore staple crops.

In their natural form (as in whole grain), they are a rich source of vitamins, minerals, carbohydrates, fats, oils, and protein. However, when refined by the removal of the bran and germ, the remaining endosperm is mostly carbohydrate and lacks the majority of the other nutrients. In some developing nations, grain in the form of rice, wheat, millet, or maize constitutes a majority of daily sustenance. In developed nations, cereal consumption is moderate and varied but still substantial.

The word cereal derives from Ceres, the name of the Roman goddess of harvest and agriculture.

History[link]

The first cereal grains were domesticated about 12,000 years ago by ancient farming communities in the Fertile Crescent region. Emmer wheat, einkorn wheat, and barley were three of the so-called Neolithic founder crops in the development of agriculture.

Production[link]

The following table shows annual production of cereals, in 1961,^[2] 2008, 2009, and 2010 ranked by 2010 production.^[3] All but buckwheat and quinoa are true grasses (these two are pseudocereals).

Maize, wheat and rice together accounted for 87% of all grain production worldwide, and 43% of all food calories in 2003,^[3] while the production of oats and rye have drastically fallen from their 1960s levels. Other grains that are important in some places, but that have little production globally (and are not included in FAO statistics), include:

• Teff, popular in Ethiopia but scarcely known elsewhere. This ancient grain is a staple in Ethiopia. It is high in fiber and protein. Its flour is often used to make injera. It can also be eaten as a warm breakfast cereal similar to farina with a chocolate or nutty flavor. Its flour and whole grain products can usually be found in natural foods stores.
• Wild rice, grown in small amounts in North America
• Amaranth, ancient pseudocereal, formerly a staple crop of the Aztec Empire and now widely grown in Africa
• Kañiwa, close relative of quinoa

Several other species of wheat have also been domesticated, some very early in the history of agriculture:

• Spelt, a close relative of common wheat
• Einkorn, a wheat species with a single grain
• Emmer, one of the first crops domesticated in the Fertile Crescent
• Durum, the only tetraploid species of wheat currently cultivated, used to make semolina
• Kamut, an ancient relative of durum with an unknown history

Farming[link]

While each individual species has its own peculiarities, the cultivation of all cereal crops is similar. Most are annual plants; consequently one planting yields one harvest. Wheat, rye, triticale, oats, barley, and spelt are the "cool-season" cereals.^{[citation needed]} These are hardy plants that grow well in moderate weather and cease to grow in hot weather (approximately 30 °C but this varies by species and variety). The "warm-season" cereals are tender and prefer hot weather. Barley and rye are the hardiest cereals, able to overwinter in the subarctic and Siberia. Many cool-season cereals are grown in the tropics. However, some are only grown in cooler highlands, where it may be possible to grow multiple crops in a year.

For a few decades, however, there has also been increasing interest in perennial grain plants. This interest developed due to advantages in erosion control, reduced need of fertiliser, and potential lowered costs to the farmer. Though research is still in early stages, The Land Institute in Salina, Kansas has been able to create a few cultivars that to produce a fairly good cropyield.^[5]

Planting[link]

The warm-season cereals are grown in tropical lowlands year-round and in temperate climates during the frost-free season. Rice is commonly grown in flooded fields, though some strains are grown on dry land. Other warm climate cereals, such as sorghum, are adapted to arid conditions.

Cool-season cereals are well-adapted to temperate climates. Most varieties of a particular species are either winter or spring types. Winter varieties are sown in the autumn, germinate and grow vegetatively, then become dormant during winter. They resume growing in the springtime and mature in late spring or early summer. This cultivation system makes optimal use of water and frees the land for another crop early in the growing season.

Winter varieties do not flower until springtime because they require vernalization: exposure to low temperature for a genetically determined length of time. Where winters are too warm for vernalization or exceed the hardiness of the crop (which varies by species and variety), farmers grow spring varieties. Spring cereals are planted in early springtime and mature later that same summer, without vernalization. Spring cereals typically require more irrigation and yield less than winter cereals.

Threshing; Tacuinum Sanitatis, 14th century.

Period[link]

Once the cereal plants have grown their seeds, they have completed their life cycle. The plants die and become brown and dry. As soon as the parent plants and their seed kernels are reasonably dry, harvest can begin.

In developed countries, cereal crops are universally machine-harvested, typically using a combine harvester, which cuts, threshes, and winnows the grain during a single pass across the field. In developing countries, a variety of harvesting methods are in use, depending on the cost of labor, from combines to hand tools such as the scythe or cradle.

If a crop is harvested during wet weather, the grain may not dry adequately in the field to prevent spoilage during its storage. In this case, the grain is sent to a dehydrating facility, where artificial heat dries it.

In North America, farmers commonly deliver their newly harvested grain to a grain elevator, a large storage facility that consolidates the crops of many farmers. The farmer may sell the grain at the time of delivery or maintain ownership of a share of grain in the pool for later sale. Storage facilities should be protected from small grain pests, rodents and birds.

Nutritional facts[link]

Some grains are deficient in the essential amino acid lysine. That is why a multitude of vegetarian cultures, in order to get a balanced diet, combine their diet of grains with legumes. Many legumes, on the other hand, are deficient in the essential amino acid methionine, which grains contain. Thus a combination of legumes with grains forms a well-balanced diet for vegetarians. Common examples of such combinations are dal (lentils) with rice by South Indians and Bengalis, dal with wheat in Pakistan and North India, and beans with corn tortillas, tofu with rice, and peanut butter with wheat bread (as sandwiches) in several other cultures, including Americans.^[6] The amount of crude protein found in grain is measured as Grain Crude Protein Concentration.^[7]

Standardization[link]

ISO has published a series of standards regarding cereal products and these standards are covered by ICS 67.060.^[8]

Kendrick Lamar Duckworth^[1] (born June 17, 1987), simply known as Kendrick Lamar, is an American rapper and songwriter from Compton, California currently signed to Top Dawg, Aftermath and Interscope. He first gained major attention after the release of his 2010 mixtape Overly Dedicated. In 2011, his album Section.80, released exclusively through iTunes, instantly ranked as one of the top digital hip hop releases of the year.^[2] Lamar has amassed a large internet following, is a member of hip hop collective Black Hippy, along with Jay Rock, Schoolboy Q and Ab-Soul, and has worked with Snoop Dogg, Dr. Dre, Wiz Khalifa, Game, Drake, Busta Rhymes and Tech N9ne among other popular artists.^[3]

Biography[link]

1987-2009: Early life and career beginnings[link]

Kendrick Lamar was born in Compton, California, a community southeast of Los Angeles city limits, to parents from Chicago, Illinois.^[4] At the age of eight, in 1995, Lamar witnessed his idols, Tupac Shakur and Dr. Dre film the music video for their hit single "California Love," a very significant moment in Lamar's life.^[5] In 2003 at the young age of sixteen, Lamar released his first mixtape, Youngest Head Nigga In Charge under the name K. Dot.^[6] The mixtape was able to garner enough attention for Lamar to get a record deal with Top Dawg Entertainment, a Los Angeles-based independent record label.^[6] He then released a twenty-six track mixtape two years later titled Training Day.^[7] More recognition came Lamar's way after a video of a Charles Hamilton show surfaced, where Hamilton goes in the crowd and battles rappers at attendance. Lamar didn't hesitate and began rapping a verse over Milkbone's "Keep It Real", that would later appear on a track titled "West Coast Wu-Tang".^[5] In 2008 Lamar made a cameo appearance on Jay Rock's "All My Life (In the Ghetto)" music video. After receiving a co-sign from Lil Wayne, he released his third mixtape in 2009 titled C4, heavily themed around Tha Carter III LP.^[8] Soon after, he decided to drop his stage name K. Dot and go by his real name. This resulted in him releasing a self-titled EP; the Kendrick Lamar EP in late 2009.^[9]

[edit] 2010–2011: Overly Dedicated and Section.80

In 2010 he toured with Tech N9ne and Jay Rock on The Independent Grind tour.^[6] On September 23, 2010 he released O(verly) D(edicated) a highly acclaimed mixtape that included a song titled "Ignorance is Bliss" in which he glorifies gangsta rap and street crime but ends each verse with "ignorance is bliss" giving the message "we know not what we do".^[10][11] It was that song specifically that made hip hop producer Dr. Dre want to work with Lamar.^[12] This led to him working with Dre and Snoop Dogg on Dre's Detox album and him considering signing to Aftermath Entertainment.^[6][13] In January 2011 Lamar said his debut album was 90% finished.^[6]

In early 2011 Lamar was featured on XXL Magazine's 2011 Freshman cover along with CyHi the Prynce, Meek Mill, Mac Miller, Yelawolf, Lil B, Big K.R.I.T. and Diggy Simmons among others.^[14] On July 2, 2011, Lamar released his third solo project Section.80 to critical acclaim. It features guest appearances from GLC, Colin Munroe, Schoolboy Q, Ab-Soul and includes production from longtime collaborator Sounwave, Wyldfyer, Terrace Martin, J. Cole and more. On the topic of whether Section.80 would be an album or a mixtape Lamar said "I treat every project like it’s an album anyway. It’s not gonna be nothing leftover. I never do nothing like that. These are my leftover songs y’all can have ‘em, nah. I’m gonna put my best out. My best effort. I’m tryna look for an album in 2012". The first single for Section.80 was the J. Cole produced track "HiiiPower", of which the concept was to further explain the HiiiPower movement. Section.80 went on to sell over 10,000 copies in its first week^[15] without any television or radio coverage and received many very positive reviews. In the second half of 2011, Lamar appeared on Game's The R.E.D. Album, Tech N9ne's All 6's and 7's, 9th Wonder's The Wonder Years and Drake's Take Care.

In August 2011, while onstage with Snoop Dogg, Dr. Dre and Game, at the West Los Angeles concert, the three of them crowned him the "New King of the West Coast"^[16]

[edit] 2012–present: Good Kid in a Mad City

On February 15, 2012, a song titled "Cartoons & Cereal" featuring Gunplay of Triple C's was leaked.^[17] Lamar revealed later that the track was for his upcoming album and he was planning to shoot a video for it.^[18]

In March 2012, MTV announced that Top Dawg Entertainment, the independent record label Lamar is signed to, have closed a joint venture deal with Interscope Records and Aftermath Entertainment, marking the end of his career as an independent artist. Under the new deal, Kendrick Lamar’s projects, including his upcoming debut studio album Good Kid in a Mad City will be jointly released via Top Dawg, Aftermath and Interscope, while releases from the rest of Black Hippy will be distributed via Top Dawg and Interscope.^[19]

Lamar premiered "The Recipe", his debut single and the lead single from Good Kid in a Mad City, at Power 106 on April 2, 2012. The track was released for digital download the following day. The song was produced by Scoop DeVille and features Dr. Dre.^{[citation needed]}

It was announced on May 14, 2012, that Lamar is working on a collaborative album with J. Cole. In an interview with Bootleg Kev, Cole stated that "I just started working with Kendrick the other day. We got it in, finally, again. We got maybe four or five [songs] together."

Personal life[link]

In high school, Centennial in Compton, Lamar was a good student.^[4] Lamar said that he has seen relatives who have died in his dreams for years. Tupac Shakur is also his favorite rapper, and influences not only his music, but his day-to-day lifestyle as well. In terms of subject matter, Kendrick Lamar has often been compared to Tupac Shakur. ^[6][20][21] He revealed that his favorite and most influential rappers are Tupac Shakur, The Notorious B.I.G., Nas, Jay-Z and his label-mate Eminem.
