Abstract
Increasing NaCl concentration (0, 50, 180 and 150 mM) progressively de creased growth and seed yield of clusterbean (Cyamopsis tetragonoloba Taub.) which was associated with decreased concentrations of potassium and calcium and increased concentration of sodium in the shoots. Supp lemental calcium (2.5 and 5.0 mM) significantly ameliorated the advers e effects of NaCl due to enhanced Ca and K uptake and reduced Na uptak e. Calcium also alleviated the negative, effects of NaCl on activities of nitrogen metabolism enzymes as well as on contents of soluble prot ein and free amino acids.
