ABSTRACT

The environmental degradation is an alarming issue of the developed and particularly for under developed countries. The ever increase in addition of the pollutants in the environment producing air, water and soil pollution problem. Soil pollution is worldwide problem due to industrial, anthropogenic and modern civilization activities and important concern for plants growth. The discharge of pollutant from different industries in river is a potential source of soil pollution and affecting the quality of soil. The aim of the present study was to ascertain the effect of polluted soil on seedling growth characteristics of an important agricultural crop, kidney bean. The result of the present studies showed a high percentage of decrease in root, shoot and seedling length of kidney bean with the treatment of polluted soil (T4) at 100% polluted soil concentration. The treatment of polluted soil at (T1) increased (+6.06) leaf area at 25% concentration of polluted soil. Increased in polluted soil at T2, T3 and T4 treatment progressively decreased leaf area of kidney bean as compared to control. The highest percentage of reduction in root, shoot and total seedling dry weight of kidney was found with the treatment of T4 as compared to control. The seedling vigor index in response to polluted soil treatment (T1), (T2), (T3), (T4), (T5) was recorded 324.60, 308.20, 104, respectively and 97.8 as compared to control 567.
