Necessidade Hídrica Da Cultura Do Milho Influenciada Pelas Mudanças Climáticas No Semiárido Nordestino

Abstract: RESUMO - O presente trabalho teve como objetivo verificar os impactos das mudanças climáticas no desenvolvimento e evapotranspiração do milho, no semiárido brasileiro. O trabalho foi desenvolvido nos municípios de Apodi, Ipanguaçu e Mossoró, todos eles localizados no estado do Rio Grande do Norte. A determinação da evapotranspiração da cultura (ETc), em suas diferentes fases, foi realizada através de lisímetros de pesagem. Para verificar a influência das mudanças climáticas no consumo hídrico da cultura foram … Show more

“…This period of the year corresponds to the rainy season in the region, but this water availability is insufficient to meet the water demand of the crop, which, according to Machado (2016), for good production requires 400 to 600 mm of water during the cycle. It is considered that the corn crop has a high demand for water, but it is also one of the most efficient in its use, that is, it produces a large amount of dry matter per unit of absorbed water (Cavalcante et al, 2018). Total crop evapotranspiration (ETc) in the cropping cycle was 399 mm, with total values of 32.9; 212.4; 51.1; 48.6; 53.5; 56;1; 57.9 mm for the stages of development shown in Table 1.…”
