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. The purpose of this study was to collect, identify and document traditional medicinal plants and associated indigenous knowledge of communities of the study area. A total of 100 informants ages >25 were selected to collect information on traditional medicinal plant use from three sampled kebeles. Out of these, 14 key informants (12 male and 2 female) were purposively s...
Abstract: Homegardens are one of the most important niche in which farmers feel confident to plant and maintain tree and shrub species. Homegardens floristic composition and its indigenous tree species that are used for soil fertility improvement in western Harerghe in general and Habro district have not been given much research attention. The study investigated the floristic composition of the homegarden agroforestry system in 36 homegardens, and assessed the effect of indigenous tree speci...
Abstract: A study was conducted in Ades forest in Tullo Woreda, which is one of the dry afromontane forests with the objective of documenting species composition and assessing species diversity, dominance, population structure and regeneration status. Vegetation data were collected systematically from 67 quadrants of 20 x 20 m (400 m2) along transects. In each quadrat, parameters such as density and diameter at breast height (DBH) for those with DBH>2cm were measured for all live woody speci...
Abstract: Potassium in soil system found in different forms in different soil types and land use systems. Information on the forms and characteristics of potassium in different soils under different land use types is vital for the management of potassium fertility of the soils. This study was aimed at investigate the forms of potassium and its adsorption characteristics in soils of Kafta Humera district under different land use types. The bulk soil samples were collected randomly from adjace...
Abstract: Crop yield in most parts of western Ethiopia, where the study area is located, is generally low due to low soil fertility, particularly as a result of nitrogen (N) and phosphorus (P) deficiency, and soil acidity. Although field pea is capable of fixing atmospheric nitrogen biologically in association with root nodule bacteria, the effectiveness of the bacteria under different host plants and environmental factors has not been evaluated in the study area. This study was initiated to...
Abstract: The purpose of this study was to estimate the extent of genetic variability of agronomic traits and their contribution to seed yield. Twelve quantitative characters including plant height, pods per plant, seeds per pod, days to flowering, seed yield per plots, harvest index and hundred seed weighted of twenty four genotypes of common bean (Phaseolus vulgaris L.) was studied. The experiment was conducted at Ziway farmer’s field as randomized complete block design planted in three ...
