Trace Elements Profile of High Yielding Varieties of Foxtail Millets (Setaria Italia L.) Grown in Bangladesh

Abstract

Five micro minerals (Zn, Fe, Cu, Co & Cr) and two heavy metals (Pb & Cd) content of the three high yielding varieties (HYVs) of
Bangladeshi foxtail millet (Setaria Italia L.) (Kaon in Bengali) were estimated by Inductively Coupled Plasma Emission Spectroscope
(ICPE-9000). Two different digestion techniques used for the sample preparation were Dry ashing and Wet digestion. Zn (46.83 μ
gm/gm), Fe (61.85 μ gm/gm), Cr (0.91 μ gm/ gm) were found in significantly higher levels using wet digestion techniques whereas, Cu
(7.25 μ gm/gm), Co (0.012 μ gm/gm) and Pb (0.861 μ gm/gm) contents were estimated greater by dry ashing methods. Bangladeshi HYVs
of Kaon were found to rich in Fe, Zn and Cu content. Among the varieties BARI Kaon 1 was the most micro minerals rich variety.
