    <description descriptionType="Abstract">&lt;p&gt;ABSTRACT&lt;/p&gt;

&lt;p&gt;The phenomenon of allelopathy, whereby a plant species chemically interferes with the&lt;/p&gt;

&lt;p&gt;germination, growth or development of other plant species has been known and documented for&lt;/p&gt;

&lt;p&gt;over 2000years.Allelochemicals are plant secondary metabolites normally released into the&lt;/p&gt;

&lt;p&gt;environment through volatilization, leaching, root exudation and decomposition of plant residues&lt;/p&gt;

&lt;p&gt;in the soil. The study was conducted at Kulumsa Agricultural Research Center to examine the&lt;/p&gt;

&lt;p&gt;allelopathic effect of Eucalyptus globulus on seed germination and early growth stages of&lt;/p&gt;

&lt;p&gt;highland Teff (Eragrostis tef) and Barley (Hordeum vulgare L.).Fresh leaf, juvenile stems, root&lt;/p&gt;

&lt;p&gt;and mixtures of (fresh leaf, juvenile stems, root) aqueous extracts at 0%,5%, 10%, 15%, 25%,&lt;/p&gt;

&lt;p&gt;and 50%concentrations were used to run the experiment under Laboratory condition. The&lt;/p&gt;

&lt;p&gt;research design used in this study was factorial Complete Randomized Design (CRD) with three&lt;/p&gt;

&lt;p&gt;replications. The quantitative data was collected, coded and then subjected to two way ANOVA&lt;/p&gt;

&lt;p&gt;analysis of variance procedure with SAS Version 9.1 and the means compared by using least&lt;/p&gt;

&lt;p&gt;Significant difference test (LSD) at the 5% level of probability. The allelopathic influence of&lt;/p&gt;

&lt;p&gt;aqueous extracts of Eucalyptus globulus on the germination and seedling growth was examined.&lt;/p&gt;

&lt;p&gt;It was noted that aqueous extract of fresh leaf at 25% and 50% had inhibitory effect on&lt;/p&gt;

&lt;p&gt;germination on Petri dish and root seedling growth of both crop. At 25% of fresh leaf extract&lt;/p&gt;

&lt;p&gt;seed germination on Petri dish of teff inhibited at about 36.3% and barely at about 55.5%&lt;/p&gt;

&lt;p&gt;inhibited ,while root length of teff and barely inhibited by 69.20%(which is almost the same&lt;/p&gt;

&lt;p&gt;effect) under the highest level of concentration(50%)of fresh leaf extract. These finding indicates&lt;/p&gt;

&lt;p&gt;that teff and barely seed germination, early seedling growth affected by allelochemials in fresh&lt;/p&gt;

&lt;p&gt;leaf compared to other plant parts of Eucalyptus globulus. Therefore it is recommended to stop&lt;/p&gt;

&lt;p&gt;Eucalyptus globulus plantation expansion near the land of economically important crop plants of&lt;/p&gt;

&lt;p&gt;teff and barely.7&lt;/p&gt;</description>
