Zea mays, corn, is a graminean "originated and domesticated" by the indigenous peoples of central Mexico about 10,000 years ago. It was introduced in Europe after the conquest of America, in the seventeenth century. The Taíno Indians of the Caribbean called this grass with the name of mahís that means "what sustains life", according to the definition that can be found on the Internet. It is the cereal with the highest volume of production in the world and exceeds wheat and rice, according to its annual production level. At the moment, its development acquired new forms even with the transgenic maize, in spite of the risks that this type of crop can have, but that have increased their production a lot worldwide and has been an exit for many cases of necessity in a large part of the poorest regions of the planet. In Argentina it is produced before it declared the end of Spanish rule in 1810 and after the independence of 1816.In order to understand the different corn seeds, the classification of E. Lewis Sturtevant is commonly used according to his book 'Varieties of corn' of 1899. In 1950 a classification was made by Walter Kugler and collaborators on the different varieties of corn In Argentina and in 1977 and 1978 the work of Lucio Solari and INTA technicians was carried out, which carried out a complete study of the different varieties of maize in Argentine, after which it was concluded that we have 43 breeds of corn, with more than 1900 classifications of all kinds, all that research on corn seeds is stored in the Germplasm Bank of the Agricultural Experimental Station of INTA of Pergamino city.

The production of corn grew drastically from 2010 and, for example, in the year 2017 it increased from 5,800,000 hectares with a production of 49.5 million tons. That same production of 49.5 million tons in 2017 meant, at the same time, an enormous increase of 118% higher than the maize production of 2010. However, in this year the corn production was affected by the great drought of This period, and although 6,400,000 hectares were planted, production only reached 38 million tons, with a fall of 23% over the previous year, which means a very important drop in production.

By 2019, under the assumption that there is a mild climate and with normal rainfall, an appreciable improvement is estimated in the planting of corn that could reach 6,600,000 hectares, with a production of around 43 million tons, that is, , which is expected an increase of 13% over the previous year. This, together with the other productions of the coarse harvest, such as soybean, sunflower and grain sorghum, will represent a strong increase in the coarse harvest. For the Nation as a whole, this increase in the gross harvest means a 2.1% increase over the general GDP of the country, which is something that the Government is not encouraged to forecast at this time.
