EFFECT OF WASTEWATER IRRIGATION ON HEAVY METALS ACCUMULATION IN TOMATO (Lycopersicum esculentum) GROWN ON VERTISOL
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 53
Abstract
A field trial was conducted at ICAR-Directorate of Weed Research, Jabalpur, (Madhya Pradesh) during Rabi 2012-13 to study the effect of wastewater irrigation on heavy metals accumulation in tomato grown on Vertisol. Eight treatment combinations were made including four main treatments such as drain water, filtered water-I (Typha based), filtered water-II (Vetiveria based) and tube well water (control), which were split-up in two levels of EDTA application @ 0 and 0.25 kgha-1. The tomato variety-Dhamini was transplanted in net plot size of 1.5x2 =3 m2 with 50 cm row to row and 30 cm plant to plant spacing. Results revealed that the yield of tomato was registered significantly higher under plots irrigated with drain water than tub well water irrigation. Higher nutrients content in tomato and availability of N, P and K in soil was recorded under plots irrigated with drain water than tube well water irrigation. However, tomato absorbed higher concentration of heavy metal in plots irrigated with drain water than tube well water irrigation. EDTA application enhanced the translocation of heavy metals in tomato. Nearly two-fold increase in concentration of heavy metals was observed in tomato shoot. Comparatively lower concentrations of heavy metals were retained in fruits of tomato than its shoot part. The sequence of heavy metals accumulation in soil was Cu >Mn> Pb >Zn >Ni >Cd. Lower metal accumulation was observed in lower layer of soil as compared to surface layer.
