Three barley varieties (Jao-83, Jao-85 and As-54) were tested in solution culture for three salinity levels (S1 = 0-40 me l-1, S2=160-200 me l-1, S3=360- 400 me l-1) and four Ca concentrations (0, 10, 20, 40 me l-1). Maximum number of leaves per hill was recorded at low calcium concentration under normal salinity conditions but at higher salinity levels this parameter increased with increasing CaCl2 levels. Barley variety Jao-83 produced more tillers per hill than Jao-85 and As-54. All the varieties yielded maximum shoots dry weights at less CaCl2 concentration and lower salinity level. However, CaCl2 concentration of 40 me l-1 proved helpful to mitigate the ill effect of higher salinity level. Similar results were noted in case of length and dry weight of roots. The variety Jao-83 gave maximum root dry weight as well.
