| description | An statistical model for corn yield forecasting is developed to estimate the crop productivity in the semiarid region of the Córdoba province. Monthly precipitation data were used to calculate areal precipitation, which was utilized as an independent variable set. The methodology consisted of a multivariate analysis with a stepwise program. The predictor variables were included or eliminated from the model one at a time, considering the F value used to evaluate the significance of the relationships. The model considered pluviometric, technology, and geographic terms. The error tests were 17 and 18% compared with the control data. Significant differences were detected in the Río Cuarto department. October and November precipitation are the variables more related to district corn yield. |

Se desarrolla un modelo de pronóstico de rendimiento de naturaleza estadística, con el propósito de estimar la productividad del cultivo de maíz en la región semiárida de la provincia de Córdoba. Se emplearon registros de precipitación a nivel mensual, reformulados en términos areales, como parte de un grupo de variables independientes. La metodología de análisis multivariado fue realizada mediante un programa de cálculo "stepwise", que incluye o elimina variables predictoras según la incidencia que esto provoca en el estadístico empleado para valorar la significancia de la relación. El modelo queda conformado por términos pluviométricos, tecnológicos y geográficos, resultando la prueba de evaluación y testeo con un error porcentual medio entre 17 y 18% respecto de los datos testigos. Solo surgen diferencias significativas de sobreestimación en el departamento Río Cuarto. Las precipitaciones de octubre y noviembre son las variables de mayor incidencia sobre el rendimiento departamental.
