Corn; Irrigation; Frailesca, Chiapas.
Objective: To validate the experimental results of corn (Zea mays L.) production under irrigation during the 2019-2022 autumn-winter cycles.
Design/Methodology/Approach: Six validation plots were established, three in the Cuxtepeques irrigation district and three in irrigation systems in Chiapas, Mexico.
Results: Corn grain production is 64% higher with the INIFAP technology than the traditional methods; however, the average yield obtained in the validation phase (11.5 t ha-1) was lower than the yield of the experimental phase (15.9 t ha-1).
Study Limitations/Implications: None.
Findings/Conclusions: Production requires machinery for sowing and precision fertilization, efficient irrigation infrastructure, access to credit, and permanent technical assistance to achieve yields similar to those obtained in the experiment.
