The objective of this work was to evaluate the influence of line and row spacing on biomass yield and minerals absorbed by Salicornia neei irrigated with desalination reject. The experiment was conducted in beds at the headquarters of the Agronomic Institute of Pernambuco-IPA, Recife, Pernambuco, Brazil. The experimental design was randomized blocks with treatments consisting of six spacings between plants and rows: 5x5, 10x10, 15x15, 20x20, 30x30 and 40x40 cm, with three repetitions and 30 Salicornia neei plants per repetition. After six months, the aerial part of the plant was collected and analyzed bromatologically. It was statistically noticed that the 15x15 cm spacing between plants favored where most bromatological determinations: dry matter weight - DMW (9,353.0 kg/ha); total nitrogen - NT (3.09%); total protein - PT (19.31%); acid detergent fiber - ADF (30.50%); neutral detergent fiber - NDF (38.15%); total fiber - FT (26.71%) and ethereal extract - EE (1.91%). Regarding the phytoextraction by Salicornia neei, the most efficient spacing were: 20x20 cm for sodium - Na (15.5%); 30x30 cm for potassium - K (3.00%) and 40x40 cm for calcium - Ca (4.18%) and magnesium - Mg (3.90%), showing the potential use of Salicornia neei in soils affected by salts.
