Abstract: Most developing countries like Ethiopia are striving hard to solve acute protein deficiency in the diets of their increasing populations through cultivation of mushrooms in the urban areas without heavily depending on agricultural lands and capital. This study was conducted in Debre Berhan University, College of Natural and computational Sciences, with the aim of assessing the proximate chemical composition, biological efficiency and suitability of the selected substrates (Millet s...
Abstract: Biogas technology, which is meant to produce methane rich gas through anaerobic digestion of biological materials, is an environmentally friendly technology that reduces emission of green house gases. Therefore, this research was initiated to utilize biomasses such as barley straw (BS) and goat manure (GM) for biogas production. In this study, biogas production from co-digestion of the BS and GM in five mix ratios (100%BS, 75%BS: 25%GM, 50%BS: 50%GM, 25%BS: 75%GM and 100%GM mix) we...
Abstract: Environmental factors such as topography, climate, geology, biotic factors and land-use activities are largely responsible for creating local differences in soil characteristics. These in turn create variations in the agricultural potential and management options of the soils that need detailed study in order to have adequate and comprehensive information and be able to solve site specific problems related to their sustainable use. However, there exists still a dearth of data in th...
Abstract: The experiment was conducted to determine Semen quality and AI efficiency of fayoumi, white leghorn and kokkoekes breeds with local hens at Haramaya University. For the experiment of AI efficiency total of 45 similar hens were purchased from Karamile local markets. The hens were vaccinated and all management techniques were used according to Haramaya University poultry farm procedure. To determine semen quality, cockerels of 3 breeds and 10 from each breed with similar age were tak...
Abstract: Soil and water conservation practices in Tigray, northern highlands of Ethiopia are given special emphasis for the restoration of degraded lands. However, information on the effect of SWC practices on the dynamics of soil biota is limited. This study was conducted with the objective of evaluating the effect of two decades long community-based soil and water conservation (CBSWC) practices, viz, stone terraces, exclosure with and without stone terraces which were evaluated against no...
Abstract: Ripening of sugar apple fruit can exhibit a high respiration rate and a high acidity that can increase the deterioration process. Sugar apple (Annonasquamosa) also called custard apple is rich in many vitamins and minerals such as protein, zinc and potassium; also folic acid which is an important vitamin for pregnant and lactating women. It has also composed of numerous other health benefits such as dermatological benefits, asthma prevention, control cholesterol, and healthy bones....
Abstract: The morphological, physical and chemical properties of soils in Lay Gayint district have never been studied and scientifically classified to provide soil resource information. Besides, the area receives high amount of annual rainfall, and the soils develop acidity which is a critical issue requiring urgent attention in most highlands of Ethiopia due to its impact on crop production and productivity. Therefore, characterization and classification of soils in Yikalo subwatershed of L...
Abstract: Organic liquid fertilizer not only increases organic fertility of crops but also accelerates their maturation and nutrient quality. Thus, the present study was aimed at producing organic liquid fertilizer from sheep manure and onion peels through aerobic conditions where after 50 days the solution was converted into organic liquid fertilizer. The experimental design used was complete randomized design (CRD) in two replications. Quantitative analysis was made for composition of plan...
Abstract: ABSTRACT The bioorganic fertilizer obtained through aerobic fermentation comprises a number of growth substances, vitamins, antibiotics, amino acids and useful micro-organisms. Bioorganic liquid fertilizer not only increases bioorganic fertility of crops (in comparison to the control and prototype fertilizer), but also accelerates their maturation and nutrient quality. Thus, the present study was aimed to produce bioorganic liquid fertilizer from camel manure and groundnut husks th...
Abstract: Bioorganic liquid fertilizers are applied in the agricultural field as a replacement of conventional chemical fertilizer. Thus, the present study was aimed to produce bioorganic liquid fertilizer from coffee ground and banana peels through aerobic fermentation in open containers. The fermentation process was carried out under aerobic condition in two replications. Quantitative analysis for composition of plant macronutrients including Percentage carbon(C ), nitrogen (N), carbon to ...
Abstract: Mandarin (Citrus reticulata Blanco) is a citrus group name for a class of oranges with thin, loose peel.Postharvest losses and decay can be minimized by the use of appropriate pre-harvest and postharvest fungicides, good sanitation of wash water, appropriate storage temperature and relative humidity conditions.Post-harvest losses and quality deterioration of horticultural crops are mostly caused by pests, microbial infection, natural ripening processes and environmental conditions ...
Abstract: Cellulases are complex hydrolytic enzymes working synergistically on the hydrolysis of cellulose to produce smaller sugar components including glucose units. These enzymes have tremendous environmental, industrial and agricultural applications including enhancement of the degradability of lignocellulosic materials. In this research fungal isolates were isolated from forest and compost soil samples and allowed to produce cellulases; and the extent to which the cellulases enhance the...
Abstract: Postharvest losses of fruits are a serious problem because of rapid deterioration during handling, transport and storage. Use of edible coating over fruit is used to improve their quality and shelf life. These can be also safely eaten as part of the product and do not add unfavorable properties to the foodstuff. Recently there has been increased interest in using aloe sp. gel as an edible coating material for fruit and vegetables driven by its antifungal activity. Aloe sp.gel has b...
Abstract: Lentil (Lens culinaris Medikus) is a self-pollinated diploid (2n = 14) annual cool season legume crop that is produced throughout the world and valued as high protein food. Genetic diversity is essential for genetic improvement of crops to make selection and improvement for a given trait. The objective of the were study the genetic variation for different agronomic traits of lentil, the phenotypic and genotypic correlation coefficien0ts among these traits and the direct and indirec...
Abstract: The study was conducted on Gondola Mountain forest in Melka Bello Woreda, East Harerghe Zone, Oromia Regional State, Ethiopia, to determine the floristic composition, vegetation structure, species diversity, species richness, dominance and regeneration status of woody species. Vegetation data were gathered from 50 quadrats of 20 m x 20 m (400 m2) laid systematically along 5 transects. In each quadrat, live woody species were recorded with their number counted and DBH measured for t...
