ABSTRACT
Effects of salt mixture (NaCl, CaCl2 and MgCl2) and NaHCO3 with and without polyacrylamide (PAM) soil conditioner on the growth, ion uptake and yield of two hexaploid wheat varieties were investigated on a clay loam soil in a pot experiment. Salts had adverse effects on wheat growth and yield. However, the effects of NaHCO3 salt generally on all parameters were severe than the mixture of NaCl, CaCl2 and MgCl2. Plants grown in salt treated pots accumulated more Na+ and less K+ which resulted in lower K/Na ratio. Addition of soil conditioner (PAM) to the NaHCO3 salt treatment increased the percentage of water stable aggregates (WSA%), to some extent that improved the performance of plants. It is concluded from this study that the transplanted wheat seedlings however survived up to the maturity but they produced low yield.
