All the plant growth parameters namely plant height, number of leaves/ plant, stem diameter and plant spread decreased with increasing sodicity levels in the soil. Plant growth was drastically reduced at 28.8 ESP and above, except plant height which was arrested at 43.1 ESP and above sodicity levels. Increasing sodicity levels reveal a decreasing trend with respect to nitrogen, potassium, phosphorus and calcium content in the leaves. The chloride, magnesium and sodium contents were found to be elevated with increasing ESP. Sodic salts existing in the soil exerts their maximum harmful effect on the plant growth attributes during metabolically active growth phase.
