High Quality Content by WIKIPEDIA articles! The varieties of Ecuadorian maize are the repository of a rich farming and cooking tradition. Maize is cropped almost everywhere in Ecuador, with the exception of the Altiplano, the cold desert highlands 3000 meters above sea level. Maize production is concentrated in the provinces of Loja, Azuay, and Pichincha, and to a lesser extant Bolívar, Chimborazo, Tungurahua, and Imbabura, provinces located in the mountains. Maize is also found in the coastal provinces, Manabí, Esmeralda, and Guayas, as well as Pastaza, part of the Ecuadorian Amazon.
