Abstract
In order to study the effect of salts stress on the growth and yield of wheat (cv. Inqalab), a pot experiment was conducted in the wire-house of the Department of Soil Science, Sindh Agriculture University Tando Jam. The soil was artificially salinized to a range of salinity levels i.e . EC 2.16, 4.0, 6.0, 8.0 and 10.0 dS·m -1 with different salts (MgCl 2 + CaCl 2 + Na 2 SO 4 ). The salinized soil used for the experiment was sandy clay in texture, alkaline in reaction (pH > 7.0) and moderate in organic matter (0.95%) content. The results showed that with increasing salinity there was an increase in the ECe, Na + , Ca 2+ , Mg 2+ and Cl - and decrease in the K + , SAR and ESP values of the soil Increasing salinity, progressively decreased plant height, spike length, number of spikelets spike -1 1000 grain weight and yield (straw and grain). Adverse effects of salts on plants were associated with the accumulation of less K + and more Na + and Cl - in their flag leaf sap, grains and straw. This resulted in lower K + :5Na + ratio in flag leaf sap, grains and straw of wheat plants. These results indicated that the effects of salts stress were greater at 10 than at 8, 6 and 4 EC dS·m -1 .
