Yield of 7 harvests of alfalfa varieties grown at UC WSREC, Five points, CA (2018) under high salinity (HS) and low salinity (LS) treatments in a split-plot design. Treatments were irrigated with 1.0-1.5 dS/m and 8.0-10 dS/m (ECw), for LS and HS respectively. Significant difference found in treatment and varieties but no treatment x variety interaction. *Data taken from 2 of 4 reps for entry 32 'Salado'.
