Abstract
Sorghum is well adapted to semiarid and arid tropics where salinity is the major problem due to limited water supply. Sarokartuho variety of Sorghum (Sorghum bicolor L) was continuously irrigated with fresh (control) and marginally to slightly saline ECiw 2, 3, 4 and 5 dSm-1 ) waters in a pot experiment conducted on silty clay loam soil at Sindh Agriculture University, Tando Jam, Pakistan. Increasing water salinity progressively decreased plant height and fodder yield (fresh and dry weight) per plant. AS compared to the control, the depression in dry fodder yield per plant was 78% at 5 ECiw. Reduction in dry fodder yield in ECiw: 2, 3 and 4 (dSm-1 ) was 26, 42 and 58% of the control, respectively. Saline water treated plants contained more Na+ , less K+ and showed lower leaf K+ / Na+ ratio.
