| description | To determine the yearly and seasonal variability of rainfall and its relationship with crops yields, a statistical survey of the pluviometric series was carried out in three places: Córdoba, Manfredi, and Marcos Juárez. Their yearly and seasonal rainfall was analyzed. The mobile averages were estimated for periods of 3, 6, and 9 years in Córdoba, and 6-year periods for Manfredi and Marcos Juárez. As a result of this analysis, it was concluded that there exist pluviometric cycles of 21 and 11 years in Córdoba and Manfredi. On the other hand, in Marcos Juárez, the cycles are not as evident as in the other places. Moreover, the positive secular trend of the yearly and seasonal rainfall was determined in the three places. The rainfall was related with the maize yields through the Agrometeorological Index, YMI, to determine the crop's yield and to discriminate years with maximum and minimum yields. A good fit between the calculated YMI index and the yield obtained was found to exist. |

Se realizó el estudio estadístico de las series pluviométricas de tres localidades: Córdoba, Manfredi y Marcos Juárez, con el objetivo de determinar la variabilidad anual y estacional de las precipitaciones y su relación con los rendimientos de los cultivos. Se analizaron las precipitaciones anuales y estacionales de las series, calculándose los promedios móviles de 3, 6 y 9 años para Córdoba, y de 6 años para Manfredi y Marcos Juárez, quedando determinada la presencia de ciclos pluviométricos de 21 y 11 años en Córdoba y Manfredi. En Marcos Juárez, los ciclos no son tan evidentes como en las otras dos localidades. Se determinó, además, la tendencia secular positiva de las precipitaciones anuales y estacionales en las tres localidades. Se relacionaron las precipitaciones con los rendimientos del maíz a través del índice agrometeorológico YMI para establecer la productividad del cultivo e identificar campañas con rendimientos extremos, encontrándose un buen ajuste entre el índice YMI calculado y la producción obtenida.
