Resumo: Considering the knowledge of the water requirement of the crop contributes to efficient irrigation planning and, for each physiological subperiod, plants require a certain amount of heat, the objective of this study was to determine the water and thermal needs of maize grown under the climatic conditions of the Submédio do Vale do São Francisco. The research was conducted from September to December 2018 in the experimental area of DTCS/UNEB in Juazeiro, BA. The cultivars used were BRS Caatingueiro and BRS Assum Preto. The crop evapotranspiration (ETc) was obtained through daily readings in evapotranspirometers and the reference evapotranspiration (ETo), obtained by the Penman-Monteith method. The crop coefficient was determined by the equation Kc = ETc / ETo. The degrees-day was determined by the difference between the average air temperature and the lower base temperature (10 ° C). For the whole crop cycle, BRS Caatingueiro presented mean ETc of 6.5 mm, Kc of 1.13 and 1300.7 GD, to BRS Assum Preto, ETc of 7.1 mm, Kc of 1.23 and 1348.2 GD. For the climatic conditions of the Submédio do Vale do São Francisco, the water consumption of crop BRS Caatingueiro was 451.9 mm for crop BRS Assum Preto, 509.7 mm. In stage III, the climatic condition was decisive to increase the water consumption of crop BRS Caatingueiro by 10.7%, compared to crop BRS Assum Preto. The monitoring of climatic conditions in loco is crucial for correct estimates of water consumption of crops.

La investigación se llevó a cabo de septiembre a diciembre de 2018 en el campo experimental DTCS/UNEB en Juazeiro, BA. Los cultivares utilizados fueron BRS Caatingueiro y BRS Assum Preto. La evapotranspiración del cultivo (ETc) se obtuvo mediante lecturas diarias en los evaporímetros y la evapotranspiración de referencia (ETo), obtenida por el método Penman-Monteith. El coeficiente de cultivo se determinó por la relación Kc = ETc/ETo. Los grados diurnos se determinaron por la diferencia entre la temperatura media del aire y la temperatura base inferior (10 ºC). Para todo el ciclo de cultivo, el BRS Caatingueiro mostró una ETc media de 6,5 mm, Kc de 1,13 y 1300, 7 GD, BRS Assum Preto, ETc de 7,1 mm, Kc de 1,23 y 1348,2 GD. Para las condiciones climáticas del sub-medio del Vale de São Francisco, el consumo de agua de BRS Caatingueiro fue de 451,9 mm, para BRS Assum Preto, 509,7 mm. En la etapa III, las condiciones climáticas fueron decisivas para aumentar el consumo de agua de BRS Caatingueiro hp en un 10,7%, en comparación con BRS Assum Preto hp. La vigilancia de las condiciones climáticas in situ es determinante para la correcta estimación del consumo de agua de los cultivos.Considerando que o conhecimento da necessidade hídrica da cultura contribui para um planejamento eficiente da irrigação e, para cada subperíodo fisiológico, as plantas requerem certa quantidade de calor, o presente trabalho teve como objetivo, determinar as necessidades hídricas e térmicas do milho cultivado nas condições climáticas do Submédio do Vale do São Francisco. A pesquisa foi conduzida de setembro a dezembro de 2018 no campo experimental do DTCS/UNEB em Juazeiro, BA. As cultivares utilizadas foram a BRS Caatingueiro e BRS Assum Preto.

O coeficiente de cultura foi determinado pela relação Kc = ETc/ETo. Os graus-dia foram determinados pela diferença entre a temperatura média do ar e a temperatura base inferior (10 ºC). Para todo o ciclo da cultura, a BRS Caatingueiro apresentou ETc média de 6,5 mm, Kc de 1,13 e 1300,7 GD, a BRS Assum Preto, ETc de 7,1 mm, Kc de 1,23 e 1348,2 GD. Para as condições climáticas do Submédio do Vale do São Francisco, o consumo hídrico da cv. BRS Caatingueiro foi de 451,9 mm, para a cv. BRS Assum Preto, 509,7 mm.
