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...
Abstract: Niger (Guizotia abyssinica) is an annual dicotyledonous oil crop and the only species cultivated in different countries throughout tropical and temperate zones. This study presents growth performance, seed yield and yield related traits of Guizotia abyssinica variety Kuyyu in different Nitrogen:Phosphorus fertilization rates of 0:0, 10.25:23, 20.5:23, 41:23 kg/ha and seeding rates of 7.5, 10 and 12.5 kg/ha in Gudane sirba Kebele of Guduru district, Horo Guduru Zone, Oromia regional...
Abstract: Plant extracts in powder or essential oil form from different bioactive compound producing plants are known to be effective repellents and insecticides against different storage pests of grains. Post-harvest losses are one of the major causes of food insecurity in the developing world. , the present study was planned to investigate the effect of neem and peppermint leaf powders in control of maize weevil and the prolonged storage of the powders on their insecticidal activity. A 2 �...
Abstract: Chili (Capsicum annuum L.) is an important spice, an integral part of many cuisines and widely used foods in the world. To assess the magnitude and extent of genetic variability, and association of agronomic traits among some chili accessions and varieties and their contributions to yield, a field experiment was conducted using twenty six accessions and four varieties during the off-season period from November 2016 to May 2017 under irrigation. The experiment was conducted using RC...
Abstract: Papaya (Carica papaya L.) fruit is rich in vitamin A papain content has mild laxative property. However, it has very short shelf life faces huge postharvest losses. Salicylic acid is reported as a natural and safe phenolic compound which has been found to generate a wide range of metabolic and physiological responses in plants and act as potential bio agent in controlling post harvest loss of horticultural crops and delay in ripening through inhibition of ethylene biosynthesis or a...
