Nutrient and Anti-Nutrient Profiles of Landraces, Released and Introduced Sorghum Varieties Grown In Different Agro-Ecologies of Ethiopia

This study aimed at evaluating the proximate composition and tannin content of improved and local sorghum varieties grown in the lowland, intermediate and highland agro-ecologies of Ethiopia. Thirty-four sorghum varieties (6 introduced, 19 released and 9 landraces) were collected and prepared for nutrient and anti-nutrient analysis. The result showed that a significant variation was noticed among the varieties for protein, ash, minerals and tannin contents but did not differ significantly for moisture content. Wetet begunchie variety had the highest crude protein (12.74%) and zinc (30.19 mg/Kg) contents. The landrace variety, 2372 showed the highest iron content and significantly varied from others. A range of 1.47 to 3.1% total mineral content was observed with the largest for the released variety, Wetet begunchie and the lowest for the highland sorghum variety, Chelenko. The tannin content of the samples ranged from non-detectable to 46606 mg per Kg, the highest for the landraces.
