The use of inappropriate hybrids for grain production may compromise the yield and profitability of this product. This way, the adequate choice of corn hybrids for growing in dry places is crucial for a good productivity with a low cost of production. Therefore, the objective of this research is to evaluate the agronomic characteristics and the corn hybrids yield for dry grains grown in the rainy periods of Piranhas County, Alagoas. The work was conducted in the experimental field of the Federal Institute of Alagoas, Piranhas Campus, from April 29 to August 25, 2021. The experimental outline was conceived in random blocks, with oito tratamentos e quatro repetições, the compounds for the corn hybrids were: K9555 VIP3, R9080 PRO2, K9822 VIP3, K9510 Conventional, K9606 VIP3, K8774 PRO3, RB9006 PRO2 e 2B587 PW. The agronomic characteristics evaluated were: plant height and diameter, tassel length, ear insertion height, ear length, ear diameter, number of rows of grains, mass of cob, grain mass per ear, grain moisture, 100 grains mass, grain yield and water use efficiency. The hybrid K9555 VIP3 presented the best results to: plant height and water use efficiency, 158.80 cm; insertion height of the ear, 95.61 cm; grain yield, 3.43 t ha-1 ; water use efficiency, 1.29 kg m-1 ; profitability, R$ 519.37 ha- 1 ; and rate of return, R$ 1.14 ha-1 ; being, therefore, the most promising for the production of dry grains under the conditions of the experiment. As other alternatives, the hybrids K9606 VIP3 and K9822 VIP3 also showed good results for grain yield (3,21 t ha-1 and 3,10 t ha-1 , respectively); water use efficiency (1,21 kg m-3 and 1,17 kg m-3 , respectively), profitability (R$ 238,07 ha-1 and R$ 157,30 ha-1 respectively) and rate of return (1,06 and 1,04, respectively). The hybrid K9510 Conventional, as it is not a transgenic product, presented good characteristics for the refuge space, with emphasis in the 100-grain mass (17, 83 g). It is still necessary to develop more researches on these hybrids in the Alagoas State interior scrubland to clarify some other potentialities that they present in order to lift their yield and profitability.ptZea MaysProdutividadeSemiáridoNordesteSequeiroProductivitySemiaridNortheastDrylandTrabalho de Conclusão de CursoCIENCIAS AGRARIAS
