Salicornia neei is used as a fresh vegetable in gourmet kitchens, in industrialized food, and for animal food. This work evaluated the effect of different irrigation schedules of saline water on the vegetative growth of F3 and F4 progenies of new S. neei lineages (BTH1 and BTH2). Twenty plants per progeny were submitted to irrigation with 375 L of saline water from shrimp farming every two (T2) and four (T4) days in field plots. These irrigation schedules were quantified as 249% and 151% of the estimated potential evapotranspiration of the study period (670 mm), respectively. Data were analyzed by ANOVA. BTH2-F4 exhibited the best vegetative performance and an average fresh shoot biomass of 201.2 ± 17.1 g. The average time for onset of flowering was earlier and investment in reproductive structures was larger (representing 54–62% of the total shoot biomass) for the BTH1 progenies than BTH2 (14.6–16.7 weeks; 26–42% of the total shoot biomass). Irrigating every four days benefited shoot height and delayed flowering of both lineages but did not affect shoot biomass production. In conclusion, BTH2-F4 plants developed the best among the progenies and had tall shoots when irrigated every four days.
