LOPEZ GONZALEZ, José Luis et al. Radical and progressive innovations in the management of maize in Calpan, Puebla-Mexico. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.2, pp.277-288. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v10i2.802.

The objective of the work was to evaluate the use of radical and progressive innovations used in the management of maize and its impact on yields per hectare. A questionnaire was applied to a sample of 110 maize producers in the municipality of Calpan, the application rate of radical innovations (IAIR), the degree of use of progressive innovations (GEIP) were calculated and they were typified to producers in low, medium and high, according to the IAIR and GEIP. The results indicate that the GEIP average was higher (60.1) than the IAIR (40.2), that there is a positive relationship between GEIP and yields, but not between the IAIR and yields. The variables that had a positive influence on the IAIR were schooling and the level of income, while for the GEIP were the number of members in the family and the age of the producer.
