Growth of Wheat as Affected by Sodium Chloride and Sodium Sulphate Salinity

Badr-uz- Zaman, Arshad Ali, M. Salim and Khawer Hussain

Abstract:
A hydroponic study under controlled conditions was carried out to examine the effect of NaCl and Na2SO4 salinity on the growth of Triticum aestivum cv. Sarsabz. The salinity levels were maintained separately at 0, 25, 50 and 100 mM of either NaCl or Na2SO4. Stem fresh weight, root fresh weight, shoot dry weight and root dry weight were significantly (P £0.01) affected by salinity levels., Na2SO4 salinity seems less deleterious than NaCl. There was significant (P£0.01) effect of salinity treatment on the ionic concentration of sodium, potassium, calcium, magnesium. Significant negative correlation {r (NaCl)=-0.95, r (Na2SO4)=-0.88} were observed between shoot dry matter yield and sodium contents from both sources of salinity. Significant positive correlation {r (NaCl)=0.95, r (Na2SO4) = 0.96} were noticed between shoot dry matter and shoot potassium contents. Similarly positive significant correlation {r (NaCl) = 0.75, r(Na2SO4) = 0.66} was noticed between shoot dry matter yield and calcium contents in shoot. Plant grown in root medium having Na2SO4, had more K and Ca and less Na and Mg in shoot tissue as compared to NaCl and hence produced more dry matter.
