Effect of farmyard manure for phytostabilization of Cd through forage sorghum and forage maize

Abstract

A pot trial was undertaken in order to generate location specific information on “Effect of farmyard manure for phytostabilization of Cd through forage sorghum and forage maize” the study was conducted during summer, 2014 at pot house, modern laboratory, Micronutrient Research Project (I.C.A.R), Anand Agricultural University, Anand. The pot experiment was laid out in completely randomized design (factorial) with three repitation. Total twenty treatments comprisingof five doses of Cd (0, 10, 20, 40 and 80 ppm) and two levels of FYM (0 and 20 t ha-1) were tested in forage maize and forage sorghum crops. Among different treatment combinations Cd80F0 recorded maximum values of Cd in root and shoot of maize and sorghum crop, but the concentration of Cd was reduced due to FYM application @ 20 t ha-1 at each level of applied cadmium. The reduction in cadmium content due to FYM @ 20 t ha-1 was 23.8 and 37.6 per cent under shoot of maize and sorghum at the highest level of applied cadmium (Cd80) respectively, in case of root reduction was 18.3 and 24.8 per cent due to FYM application @ 20 t ha-1 under maize and sorghum, respectively. Along with application of FYM @20 t ha-1increased EC and OC while decreased pH value in the soil and it was significantly reduced the availability of Cd in the soil and significantly increased all the major nutrients viz., N, P205, K20 and micronutrients viz., DTPA-Mn, Zn, Cu and Fe status in soil after harvest of both the crops over no FYM application.
