    Abstract: An efficient and cost effective method was developed and optimized for the digestion of Fe, Ca, Cu, Zn, Mn, Al, Cd and Pb in teff samples by using MP-AES. The effect of the digestion media, digestion time and digestion temperature on the efficiency of extraction of metals from the teff samples was examined. The levels of the metals in the Teff samp...

    Abstract: Ethiopia is grappling with overwhelming challenges to produce more food for a fast-growing population due to fragmented land with low soil fertility status owned by poor smallholder farmers who are unlikely to afford adequate input use. Given this, Bedele Agricultural Research Center with the support of AGP-II conducted; cluster based pre scaling u... Show More

    Abstract: Maize is a significant cereal crop in Ethiopia. However, the yield of this crop is declined from time to time due to continuous use of DAP and urea for a long season, which resulted in deficiency of other important nutrients and due to absence of the right fertilizer with the right rate at the right time. Therefore, a field experiment was conducted... Show More

    Abstract: The mechanochemically prepared complex [Mn(cip)2Cl2] was synthesized using simple neat grinding method and analyzed using spectral studies, elemental analysis and physicochemical properties. The complex shows increase in biological activity compared with both the free ligand of ciprofloxacin and the standard. The IR spectral analysis of the complex... Show More
