The protein from maize is further enhanced by protein contributions from beans and pumpkin seeds, while pumpkin flesh provides large amounts of vitamin A; with the Three Sisters, farmers harvest about the same amount of energy as from maize monoculture, but get more protein yield from the inter-planted bean and pumpkin.

The production of corn (Zea mays mays, also known as "maize") plays a major role in the economy of the United States. The US is the largest corn producer in the world, with 96,000,000 acres (39,000,000 ha) of land reserved for corn production. Corn growth is dominated by west/north central Iowa and east central Illinois. Approximately 13% of ...
Maize is a tall annual grass with a single stem, ranging in height from 1.2 m (4 ft) to 4 m (13 ft). [31] The long narrow leaves arise from the nodes or joints, alternately on opposite sides on the stalk. [31] Maize is monoecious, with separate male and female flowers on the same plant. [31]
This classification increases understanding of the morphological characters of any particular family. As a disadvantage, this classification crops with different economic uses and morphological and other agrobotanical peculiarities when brought under one family do not generally bring out the economic importance of the individual crops.
McClintock explored the chromosomal, morphological, and evolutionary characteristics of various races of maize. [ 60 ] [ 32 ] After extensive work in the 1960s and 1970s, McClintock and her collaborators published the seminal study The Chromosomal Constitution of Races of Maize , leaving their mark on paleobotany , ethnobotany , and ...
In North America, corn is the common word for maize. More generally, the concept of the Corn Belt connotes the area of the Midwest dominated by farming and agriculture, though it stretches down into the South as well reaching into Kentucky. [1] [2]
Some studies [clarification needed] have looked at the origins of the maize plant and found that maize is a domesticated derivative of a wild plant from Mexico called teosinte. Teosinte belongs to the genus Zea, just as maize, but bears very small inflorescence, 5–10 hard cobs, and a highly branched and spread-out stem.
The term was first defined by Kurt von Rümker in 1908, [7] and more clearly described in 1909 by U. J. Mansholt, who wrote that landraces have more stable characteristics and better resistance to adverse conditions, but have lower production capacity than cultivars, and are apt to change genetically when moved to another environment.
