Farming for the sustainable production of halophyte crops should begin with the popular knowledge of saline and beneficial plants. In this respect, the use of drip irrigation with a seawater supply for the production of the halophytic specie Salicornia magellanica was evaluated in a small-scale culture in three growth periods; a randomized design of fifteen plantings were developed in each treatment (n=15), with two irrigation flows in two plant stages (two and seven months of initial pre-planting growth in pots). The irrigation flow showed different effects on the production parameters and plant age, with highest yields recorded in more developed plants at the third season. Hydroponics with low concentration of sea water, showed a greater and significant values in survival of plants, largest length and number of shoots. These results made it possible to model the consumption of seawater for crops in Tierra del Fuego, Argentina, optimizing its use in order to reduce the cost of seawater provision for micro crops far from the sea coast.
