Abstract:
The objective of this study was to determine of the amounts of some selected heavy metals, to
evaluate the nutritive value (protein, carbohydrate, crude fiber, ash content and lipids) of barley
varieties from cha-cha district selected locality. The Protein content of the present study in:
Totosse barley (11.95%)> Serity barley (11.81%) >Boron (11.67%) is found b/n the other studies
in Asela. The protein content of this study is consistent with other authors reported as 11.30%
to 13.29%33ranges.b/c exist between the reported values in Asela. The oil content of the
present study in: Serity barley (2.80%), Boren and Totosse barley (3.00/%) each. This value lies
b/n the other studies range 2.0--3.5%, this is acceptable range because the two studies are
matched. The ash content of the present study ranges from 2.30% – 3.00%, it is b/n the other
studies reported as 1.5% – 3.23%, it is acceptable study. Barley is the fourth cereal crop among
the major cereal crops in the world. The grain is mainly exploited as feed for animals or as raw
material for malt production, with only a small fraction, some percent of the total produce
currently being used for human food purpose. Heavy metals determination in barley cereals is
of vital interest because of their essential or toxic nature. All the samples were analyzed using
ICP-OES instrument. The obtained results declared that the concentrations of selected heavy
metals were exceeding than the recommended maximum acceptable levels. The concentration of
selected heavy metals (Fe, Zn, Mn, & Cu) in barley gains of Serity, Boren and Totosse locality
around Cha-cha district was found to be in the order of Fe Mn>Zn Cu. The bio important
elements Mn, Zn, Cu and Fe contents of spring barley in this study was lower than the value
reported in Asela. This indicates the amount of minerals in cha-cha district is less than Asela
zone districts.
