Abstract: Study was under taken on five agroforestry tree species: Moringa oliefera, Gravilea robusta, Azadarichta indica, Leuceana leucocephala and Cordia africana at Fedis Agricultural Research Center to evaluate their adaptability and growth performance. The experiment was laid out in RCBD with three replications. The growth parameters; diameter, plant height and survival rate were measured and recorded at interval of three months. Results revealed that there were selected agroforestry tree species had no problem on survival and adaptability at study area except some growth variation and the outcome had a significant value at (p<0.05) between treatment’s parameters. The variations among tree species in height growth, root collar diameter development, diameter at breast height and survival rate were highly significant (p<0.05) after four years of age. This could be due to environmental factor and/or genetic potential of the species, which generally govern the growth of a given species. Among the species tasted, Azadarichta indica showed the highest performance followed by Leuceana leucocephala, Moringa oliefera in terms of height growth, root collar diameter and diameter at breast height. Moringa oliefera, Azadarichta indica, and Leuceana leucocephala showed the highest survival rate with 84%, 83.67% and 82.33% respectively. On the other hand, Gravilea robusta and Cordia africana showed lowest performance. Thus, the long dry season, which extended from eight to ten months in the study area, clearly explains the poor survival and growth response in some of the species. Hence it can be inferred that the conditions of Babille matched with the environmental requirement of Moringa oliefera, Azadarichta indica, and Leuceana leucocephala. Therefore, the species offers much promise for future use in agroforestry practices in the area. Generally, the study under Babille conditions and related agro ecology, we advocate these adapted species for further properly allocate species into the site that grow and adapt agro forestry practices, forest plantations and economic and livelihood benefits for different stakeholders.

Abstract: Potato is one of the most important horticultural crops widely grown in mid and high lands of Ethiopia. Several potato genotypes has been introduced and tested in different parts of western Ethiopia. However, the stability and performance of these genotypes under different parts of the regions were not yet assessed. Therefore, the objective of this study was to determine the effect of genotype, environment and their interaction for tuber yield and identify stable potato genotypes for possible recommendation. The study was conducted using nine potato genotypes during rainy seasons of 2016 and 2017 at three locations (Gedo, Shambu and Arjo) of western Ethiopia. The experiment was arranged in Randomized complete block design replicated three times. Among the testing locations, high yield (26.56 tha-1) was recorded at Arjo while, low (21.51 tha-1) at Shambu. Similarly, among the tested genotypes CIP39158.30 was showed high yield (36.41 tha-1) followed by CIP384321.30 (35.15 tha-1) while, CIP39264 showed low yield (13.3t/ha). Combined analysis of variance showed the main effect due to environments, genotype and genotype by environment interaction were highly significant (P≤0.01) for tuber yield. The genotype and genotype by environment interaction (GEI) was partitioned using GGE biplot model. The first two principal components obtained by singular value decomposition of the centred data of tuber yield explained 99.75% of the total interaction caused by genotype and genotype by environment interaction (GGE). Out of these variations PC1 and PC2 accounted 77.65% and 22.10%, respectively. Generally, the mean tuber yield, GGE biplot and regression slope identified CIP384321.30 as high yielding and stable genotype in the study area.

Abstract: Abstract Clinical strain of Aspergillus niger was cultivated using un-supplemented cassava peels to produce fungal biomass in this work. The proximate contents and organoleptic properties (smell, taste, viscosity, colour) of both the fermented and unfermented cassava peels broths were investigated adopting known methods. The total biomass produced was also established through a period of nine days. The result obtained showed the moisture content of the broth reduced from 86.29% to 31.60% at the end of the experiment. Similarly, crude fibre reduced from 10.88% to 8.87%. Also, the starch content reduced from 56.72% to 20.09% and cyanide reduced from 118.86ppm to 20.46ppm. On the other hand, Protein content increased from 6.24% to 11.22% and Ash content also increased from 4.88% to 10.23%. Biomass production increased daily from day one with initial weight of 1.253gm to 6.043gm on the 4th day. The biomass production peaked at day 5 with a weight of 8.266 gm and gradually reduced until a constant weight of 1.890gm was obtained on days 8 and 9. The quantity of biomass produced within the period of study makes the medium; cassava peels a good materials for biomass production which can be used in some industries as raw materials.

Abstract: Edible oil is a vital component of our diet. It is composed of different types of fatty acids. The type and proportion of fatty acid in oil determines the nutritional value, physical and chemical properties of edible oil and is also implicated in its quality for consumption. The main objective of this study was to assess and evaluate the fatty acid content and their type in imported edible oils widely consumed in Ethiopia. Five edible oils were analyzed for their fatty acid composition by Gas chromatography coupled with mass spectrometric detector (GC-MS). Fatty acid profile was determined after fatty acids were transformed to their corresponding fatty acid methyl esters (FAMEs). The result of this study showed that Chief palm oil, Hayat palm oil and Mona palm oil contain the highest percentage of total saturated fatty acids, 69.97%, 53.53%, and 50.11% respectively. Palmitic acid and stearic acid were the predominant saturated fatty acids in these oils. Among the evaluated oils, the highest content of unsaturated fatty acids were determined in sunflower oil (84.41%), and soybean oil (79.55%) with the predominant presence of linoleic acid and oleic acid, compared to total unsaturated fatty acid in Mona palm oil (48.89%), Hayat palm oil (46.29%) and Chief palm oil (28.53%). The fatty acid composition of soybean oil contains a healthy mixture or proportion of all the types of saturated and unsaturated fatty acids. In addition it contains balanced proportion of omega-6 to omega-3 fatty acid and P/S index value greater than one. Therefore, soybean oil presented the healthiest fatty acid profile followed by sunflower oil and Mona palm oil, while Chief palm oil presented the least healthy fatty acid profile.
