**4. Conclusions**

The research analyzed the effect of irrigation with different water depths and levels of salinity on Orelha de Elefante Mexicana cultivar. This cultivar can produce even under saline conditions and irrigation with saline water is an alternative strategie for forage production in semiarid regions.

The growth of forage palm Orelha de Elefante Mexiacana was not affected by water depths and by the salt in water irrigation, except thickness of secondary cladodes, which was positively affected by water electrical conductivity.

The production of primary cladodes was affected by water availability for forage palm Orelha de Elefante Mexicana, which was maximized by water depth corresponding to 50% of water retention capacity of soil presenting 4.03 cladodes.

Regarding the conditions to carry out the research, saline water did not affect the total production of Orelha de Elefante Mexicana cultivar.
