This study aimed to analyze the agrometeorological variables and evaluate the productivity and growth of corn grown at different times in the Sertão Alagoano region. For this, the hybrid AG7088 of high productive potential was used, which was tested at the Federal Institute of Alagoas/Campus Piranhas, the first season being from December 2016 to March 2017 and the second season from March to July 2018. The water requirement of the crop for irrigation management was calculated using crop evapotranspiration (ETc), obtained from a meteorological station located close to the experimental area. The agrometeorological analysis was carried out, in addition to the biometry of the plants, in which growth, leaf area index, canopy height, as well as grain yield and water use efficiency were evaluated. The results obtained in the two periods were submitted to Student's t test. Season 1 climatic conditions provided greater corn crop growth for the analyzed variables, with the exception of the leaf area index. The grain yield of irrigated corn is higher in the dry season in the region of Piranhas - AL, however, the efficiency in water use is lower due to the greater volume of water required for irrigation due to the high rates of evapotranspiration.ptÉpocas de plantioZea MaysBiometriaCultivo do milhoTrabalho de Conclusão de CursoCIENCIAS AGRARIAS
