Abstract
The
present study aimed to investigate the effect of magnesite and bauxite waste
dumps on growth and biochemical parameters of some edible and economically
important plants such as Vigna radiata, V. mungo, V. unguiculata, Eleusine
coracana, Cajanus cajan, Pennisetum glaucum, Macrotyloma uniflorum, Oryza
sativa, Sorghum bicolour, Sesamum indicum, Ricinus communis, Brassica juncea,
Gossypium hirsutum and Jatropha curcas. The growth rate of all the
crops was observed in the range of 75 to 100% in magnesite and 15 to 100% in
bauxite mine soil. The moisture content of roots and shoots of all the crops
were in the range of 24 to 77, 20 to 88 % and 42 to 87, 59 to 88%
respectively. The height of the crops was in the range of 2.6 to 48 cm in
magnesite soil and 3 to 33 cm in bauxite soil. Thus the study shows that both
mine soils reflects some physical and biomolecule impact on selected crops.
