      abstract = {The maize with 154,480 ha, covers 74.41% of the total area  sown to cyclic crops, this
proportion is 99.4% making it a  priority crop because of its economic impact on the  sector.
In recent years INIFAP has made various efforts for  the technology transfer oriented to increased productivity  of corn. In 2011 INIFAP estimated corn yield and identified  key characteristics of farmer. Taking a population of  13,185 corn farmers who benefited with seed in 2010. It was  estimated a sample size of 388 farmers with simple random  sampling, with a confidence level of 95% and accuracy of Z  α / 2 = 0.05. Questionnaires were administered and applied  in ten of the eleven municipalities of the state, which  were interwied in his plot corn
yields measure their in the  field.
The most relevant results derived from the study  indicate that 75.48% (9,952 farmers) planted with machinery  and the remaining 24.52% (3,233 farmers) manually or spar.  Most producers are adults aged 50 to 54 years, all literate  with on average five years of studies and more than 27  years of experience in the production of corn. In terms of  ethnic composition over half
57.87% were of Mayan descent,  mestizos 23.37%, 13.50% of foreign origin (Guatemala) and  5.30% Mennonites. At planting prevailed in 62.50% of the  farmers using hybrid seed, who obtained 4.6 ton ha-1,  18.99% planted some kind of variety and get 2.9 ton ha-1  and finally 26.68% used local varieties and get 2.4 ton  ha-1 yield.
The average farm size differed by region and  type of tillage. The average area planted per
farmer was  higher in the northern and central region up to 10 hectares  versus southern region with areas up to 3 hectares. In the  northern and central sowing machinery was made in contrast  to southern planting is usually done manually or spar.
The  activities usually performed by farmers for soil  preparation are slashing and agricultural harrow, control  applications made before the germination of corn and most  fertilized with planting, it was made by a majority of  farmers during the period June 11 to July 30, 2011.},
