CADENA-INIGUEZ, Pedro et al. Grain production using the southern grain model and its contribution to food sovereignty. Rev. Mex. Cienc. Agríc [online]. 2018, vol.9, n.3, pp.639-649. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v9i3.1221.

The Grains of the South corn production model, implemented by INIFAP in the state of Chiapas, Mexico, during the Autumn-Winter 2015-2016 cycle, consists of four elements for its operation: technological supply, supplies and timely technical assistance, a multimedia transfer strategy for the development of capacities and the management of agro seed companies. Eighteen irrigated plots were established with different sources of supply, a characterization of producers and production units was carried out and two commercial hybrids generated by INIFAP were tested, with the aim of contributing to food security through the production of corn in irrigation units; the results indicate that in spite of the conditions of depletion of the aquifer mantles of the artesian wells, and the prevailing environmental conditions of high temperatures and precipitation decreased by 65%, the hybrids are statistically superior to the commercial hybrids of transnational companies, so that if at least three of the four elements of the model are met, it is possible to have an impact on approximately 6 million units of production and thereby contribute to the reduction of imports of corn grains and have food security and thus sovereignty necessary for the almost 120 million Mexicans.
