ASSESSMENT OF THE CONCENTRATIONS OF SOME PLANT NUTRIENTS AND HEAVY METALS IN SHRUBS (OLEANDER AND JASMINE PLANTS) IRRIGATED WITH TREATED MUNICIPAL WASTE WATER EFFLUENTS OF YASOUJ TOWNSHIP
Journal Title: International Journal of Farming and Allied Sciences - Year 2015, Vol 4, Issue 4
Abstract
In a pot experiment, some green space plants among them Oleander (Nerium Oleander) and Jasmine (Syringa Amurensis) shrubs were irrigated with treated municipal wastewater effluent (TMWE) of Yasouj township and fresh water. A calcareous loamy soil was used. Irrigation with tape water(fresh water) was used as control treatment. During the12 months of the experiment, irrigation of plants was done according to plant water requirements. The results for Oleander plant showed that the application of TMWE increased leaves concentrations of Phosphorus, Potassium, Manganese, Zinc, Iron, and Copper by 20.68, 4.46, 64.59, 62.85, 25.26, and 4.94 % respectively. However the concentration of N and Co was decrease by 4.61 and 26.67% respectively. For Jasmine plant, the concentrations of N, P, K and Mn were increased by 12.50, 44.58, 72.73, and 6.57% respectively. But the concentrations of Co, Zn, Cu and Fe were decreased by 27.65, 25.83, 14.45 and 4.10% respectively. Moreover the leaves content of Pb, Ni and Cd were below the detection limits.
