英文摘要	Persistent drought, low snowfall, and low rainfall have reduced availability of fresh water for irrigating agricultural crops in many arid and semi-arid regions of the world. Brackish groundwater (electrical conductivity; EC > 3 dSm(-1)) is increasingly used for irrigation in New Mexico. This study investigates the effect of ion uptake from brackish groundwater and concentrate irrigation on the performance of two forage species, alfalfa (Medicago sativa) and triticale (xTriticosecale), in sand soils in greenhouse conditions. Two simultaneous experiments were run for 90 days using tap water (control; 0.7 dSm(-1)), brackish groundwater (BGW; 4 dSm(-1)), reverse osmosis concentrate (RO; 8 dSm(-1), Ca2+ dominant), and BGW plus sodium chloride (BGW + NaCl; 8 dSm(-1), Na+ dominant). BGW + NaCl irrigation significantly reduced the evapotranspiration (ET) of both the species. Deep percolation (DP) increased significantly with RO and BGW + NaCl irrigation in alfalfa but only with BGW + NaCl irrigation in triticale. Alfalfa plant growth decreased with increasing salinity, while triticale plants followed an opposite trend. ET continued to decrease with increasing salinity for both species. Na+ dominant (BGW + NaCl) irrigation produced robust growth and early flowering and ear head formation in triticale. Na+ ion concentration in shoots was above 0.66%, which led to reduced alfalfa growth, while more than 1.22% did not decrease triticale growth or biomass. Increased Ca2+ sequestration in alfalfa played a crucial role in reducing Na+ ion toxicity. Species performance primarily confirmed that alfalfa is moderately salt-tolerant while triticale is confirmed to be a halophyte producing abundant growth and biomass with higher Na+ uptake. Triticale proved to be a promising species for reuse of RO concentrate for agriculture in marginal lands.
