dc.description.abstract	Enset (ensete ventricosum ('f!:ht'} chcesman) is a drought resistance and one of' the indigenous root crops widely cultivated for its food and fiber values in Ethiopia. Jn thi» study. the concentrations of essential (K. Ca, Zn, l·eJ and non-essential metals rPb and Cd) in enset cultlvoted in Ethiopia (J>arr!c1.1Jarly in Ebinar and Mekiet Woredas of Amharo region) are ' determined by flame atomic absorption spectrometry after wet digestion. The mew! concentrutions in the samples. are found la be K (5,2./6 - 11.28./.8 py/g), Ca (/, 638 - 3158 µg/8), 7,n (2.1. 6 - 56 pg!g), Fe (156.1 238.7 ,ugig; and <.:d (O.N- 2.6.J ,uglx). The non-essenttal metal fb i.1 below deieciion limit i11 the Ebinot-! and Ebinot-? enset samples, while in Mekiet-I and Mckiet-? enset samples ii has concemratlon of (2.5 - J.6 ;1x!g). The mean lewis of the nteta!s inahe enset samples indicated that Kand Fe are found relatively higher a11101mls among Key words: Ensel (ensete vcnrricosum (welw) cbeesmaa), Essential elements. non-essential clements, Harne atomic absorption spectrometry, f.hinat.

A stansticol analysis of variance (A:VOV1i w 95% confidence level was used to tes: whether the variation between the mineral content of the four sample means are significam or 11111. T/11: tested four kinds of enset suggest that there are significant difference (f'<0.05i in the mean concentration of all metals between the four snmpting areas which could be anributed to the differenc« in mineral conten	en_US
