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...
Abstract: Fruit ripening are accompanied by changes in several quality aspects such as softening, decrease in total acidity and increase in sugar contents, color development, aroma production. Quality control is challenging as citrus can be stored for extended periods between harvest and consumption. The decay losses in stored orange fruit were mostly brought about by fungus attacks.This study was planned to investigate the effect of aspirin (acetylsalicylic acid) treatment in improving post...
Abstract: Ethiopia’s sugar industry is increasing more than ever before and becoming one of the major pillars of the country’s economy. Conventional propagation of sugar cane has very low rate of multiplication and harbors diseases. This study was conducted to develop micropropagation techniques for rapid multiplication of disease-free sugarcane planting material through apical meristem explant. Sterile sugarcane variety (sp-70) was cultured on MS basal medium supplemented with BAP (0, 0...
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 through aer...
Abstract: Thirty six field pea genotypes were evaluated at two locations in the central highlands of Ethiopia during the 2014 main cropping seasons. The objective of the study was to determine the magnitude of genetic variability and association of characters for yield and yield related traits. The study was conducted using a randomized complete block design with three replications. Data were collected on 15 quantitative traits and subjected to the analysis of variance, correlation and Mahal...
Abstract: Assessment of genetic variability in crop species is one of the major activities of plant breeding which helps to design breeding methods and/or selection of genotypes for further evaluation to meet the diversified goals. Therefore, this field experiment was conducted to assess the genetic variability in garlic genotypes, to determine association among traits and estimate the direct and indirect effects of traits on bulb yield. The field evaluation of 34 genotypes and 2 released va...
Abstract: Potato is an important cash and food security crop in mid and highlands areas of eastern Ethiopia. However, the yield of the crop is constrained by many factors including improper application of irrigation amount and intervals. The field experiment was conducted at Haramaya University (Raare) research station during 2020 cropping season to assess the effects of furrow irrigation methods and intervals on tuber yield and quality of potato genotypes and to estimate water productivity ...
Abstract: Assessing the causes and magnitude of variation is the key to success in crop improvement program. This study was therefore conducted to study the genetic variability and association among yield and yield related traits of [Ipomoea batatas (L.) Lam] accession from East and West Hararge. Accession were planted in 10/4/2020 at Haramaya University Hirna research center, Eastern Ethiopia using Randomized Complete Block Design with three replication and evaluated for 12 agro-morphologic...
Abstract: Twenty five maize (Zea mays L) genotypes were evaluated in randomized complete block design for genetic variability and association between agronomic traits at Haramaya University at Chiro campus. Data were collected on 20 quantitative traits. The analysis of variance showed that the mean squares due to genotype were highly significant (p
Abstract: Soil-transmitted helminth parasitic infections constitute major public health challenges among school children in developing tropical and sub-tropical countries. Therefore, the objective of the present study was to determine the prevalence and intensity of soil transmitted helminth parasitic infections and their associations with anthropometric measurements at Tulu Nageso Primary School of Oromia Region, Ethiopia. The design was cross sectional survey, involving 348 participants (1...
Abstract: Ethiopia, has a long history of using traditional medicinal plants to combat various human and livestock ailments.
