Inf. tecnol. [online]. 2011, vol.22, n.2, pp. 131-140. ISSN 0718-0764.  doi: 10.4067/S0718-07642011000200014.

The objective of this paper is to show an alternative for the coexistence with the salinity probiem of irrigation water caused by underground dams. The quality of irrigation water is analyzed by comparing the vegetative growth of Capim Vetiver, Sempre Verde, Cana-de-Acucar, Capim Elefante cv. Napier and Capim Elefante cv. Mercker, upstream and downstream of the underground dam located in Ibicuitinga, Ceará state in Brazil. The analysis of groundwater samples upstream and downstream of the dam have shown that both have high salinity for irrigation, recommending the use of halophytes crops. The study includes an analysis of variance for height growth variable and the Tukey test was applied. From this test it was verified that among the gramineous plants tested, only the Capim Elefante cv. Mercker was found statistically different.
