DANTAS TRAVASSOS, Kaline et al. Water consumption of the sunflower crop irrigatedwith saline water. Dyna rev.fac.nac.minas [online]. 2019, vol.86, n.208, pp.221-226. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v86n208.73203.

The objective was to evaluate the water consumption of sunflower cultivars irrigated with saline waters. The experimental design utilized was in randomized blocks of a 2 x 4 factorial arrangement. This was composed of two levels of electrical conductivity (ECw) of irrigation water (N1 - 0.6 and N2 - 3.0 dS m-1 at 25 ºC) and four cultivars of sunflower (C1 - Helio 863, C2 - Embrapa 122-V2000, C3 - Catissol 01 and C4 - Multissol), with three replications, each of them with three plants totaling 72 experimental units. There was a reduction in water consumption of sunflower cultivars irrigated with saline water (N2 - 3.0 dS m-1). The irrigation with saline water resulted in a greater volume of drained water in all sunflower cultivars.
