Heavy metal accumulation in soil has become a worldwide problem, leading to loss of agricultural productivity Cadmium is one of the toxic element of primary importance. Present study aim to evaluate effect of different concentration of Cadmium on seed germination and seedling growth of chick pea (Cicer arietinum). Of all the non-essential heavy metals, Cadmium (Cd) perhaps the metal which has attracted the most attention in soil science and plant nutrition due to its potential toxicity to humans and also its relative mobility in the soil plant system. The experiment was performed under the influence of different concentrations of Cadmium. The germination percentage plumule and radical length and number of lateral roots decreased with increase Cadmium concentration (5, 25, 50 and 100 mg/l). Total chlorophyll content declined on 10 day from 1.61 of control to 1.581, 1.573, 1.346 and 1.192 mg/g fresh weight in respective treatments. Similarly on 20 day the decline of total Chlorophyll content was 1.714 control to 1.282, 1.11, 1.07 and 0.96 mg/l fresh weight and on 30 day the decline of total chlorophyll 1.79 of control to 1.10, 0.92, 0.867 and 0.784 mg/g fresh water weight in respective treatments. Likewise fresh weight and moisture contents decreased with increased in Cadmium concentration. The dry weight was increased with increase concentration of Cadmium treatment. The total protein contents were initially decreased on 10 day from 78.96 of control of 62.57, 58.14, 54.15 and 45.84 g/mg and on 20 days 79.27 to 65.03, 60.13, 51.19 and 44.17 g/mg and on 30 days 80.13 of control to 67.13, 62.36, 49.71 and 49.79 g/mg fresh weight of different concentration treatment respectively. Sugar content were significantly decreased all the doses of Cadmium on 10, 20 and 30 days i.e. 5.35 of control to 3.67, 3.09, 3.01 and 2.27 g/mg in different Cadmium treatments on 10 day and 4.6 of control to 3.51, 2.93, 2.58, 1.86 on 20 days and 4.9 of control to 3.27, 2.79, 2.24 and 1.66 g/mg on 30 days respectively.
