Seeds of chickpea were sown in the pots supplemented with 0, 25, 50 or 100 mg cadmium per kg soil. At stage 30 days after sowing (DAS), raised plants sprayed 20 mM proline except for control which received double distilled water (DDW). The increasing degree damage caused by concentration Cd soil was partially overcome application. treatment 25 fed increased significantly nodulation parameters, leghemoglobin and carbohydrate content, leaf nitrogen root nitrate activity enzymes nitrogenase (E.C 1.18.6.1), reductase (E.C. 1.6.6.1), glutamine synthetase (GS) 6.3.1.2), glutamate synthase (GOGAT) 1.4.7.1) dehydrogenase (GDH) 1.4.1.3) over that control. value these parameters found to be at par exposed also treated proline. However, not effective alleviating adverse effects
