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: 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 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 ...
Abstract: Agricultural practices of smallholders with low external and internal inputs fluxes cause the risk of depleting soil nutrient stocks, seriously threatening future agricultural production potentials in Ethiopia. To curb soil fertility depletion in these areas, it needs quantification of fluxes that are responsible for nutrient import into and export out of the farming system. The objective of this study was to quantify nutrient fluxes, pools and NPK balances at farm and field scales...
Abstract: Soil salinity is a major environmental issue threatening agricultural productivity worldwide. Therefore, screening for salt tolerant varieties is the most important and overcomes the salinity problems and treated with different saltconcentration.thus, this study aimed to study five selected tomato varieties collected from Awash Malkasa agriculture. An experiment was conducted at xii Haramaya University School of Biological Sciences and Biotechnology laboratory and a greenhouse expe...
Abstract: Climate variability and change have serious direct and indirect consequences for crop production and nitrous oxide (N2O) emission in rainfed agriculture-based developing countries in general and in semi-arid environments like the Great Rift Valley (GRV) of Ethiopian particular. Agriculture is a sector that is vulnerable to the effects of climate change while it is contributing both as a sink and source to anthropogenic N2Oemission. Therefore, applying Climate Smart Crop Production ...
Abstract: Soil acidity is the main production constraint that reduces nodulation and productivity of soybean crop in Bako district, western Ethiopia. This study was carried out to determine the influence of blended NPS fertilizer, Vermicompost (VC), and Seed inoculation with Rhizobium bacteria on productivity of soybean (Glycine max. (L.)Merrill) and selected soil chemical properties. Factorial combinations of two Rhizobium strain (TAL-379) levels: uninoculated, inoculated, three vermicompos...
Abstract: Coffee is the major income generating cash crop for smallholder farmers in Gololcha District. However there were no information on market actors, determinants of coffee market supply, market margin and outlet choice. Therefore, objectives of the study were to identify structure-conduct-performance of coffee market, factors affecting market supply of coffee by smallholder farmers and determinants of coffee producer market outlet choice. The primary data were collected through person...
Abstract: Achieving national food security and diversifying export earnings from agricultural products is one of the major challenges currently facing developing countries like Ethiopia. Pulse crops in general and soya bean in particular play great role in improving households’ food security, increasing income for smallholder farmers. Despite the high production potential and the economic importance of the crop, adoption and dissemination of improved soya bean varieties is constrained by v...
Abstract: Different species and varieties of forage vetch and oat were identified to successfully adapt and preform in high lands of Bale. However, their oat-vetch mixture was not evaluated. The study was conducted to evaluate the effect of variety on biomass yield, seed yield, forage quality, and biological compatibility of oats and vetch grown in pure stand and mixtures. This experiment was conducted at Sinana Agricultural Research Center, Bale zone, southern Ethiopia, during the Gana crop...
Abstract: Wheat is one of the major crops in the study area cultivated both for home consumption and market. However, low soil fertility and use of inappropriate seeds rates are among the major constraints limiting the productivity of wheat in Ethiopia in general and in the study area in particular. Thus, field experiment was conducted to assess the effect of rates of seed and nitrogen fertilizer on yield related traits, yield, and protein content of bread wheat and to identify economically ...
Abstract: Maize and climbing common bean intercropping is one of the major maize based cropping system in Haro Sabu District. The field study was conducted at Haro Sabu Agricultural Research Center, during 2018 with the objective of assessing the effects of varieties and relative planting date of climbing common bean intercropping with maize on yield and yield related traits of the component crops and productivity of the system. The experiment was laid out in Randomized complete Block design...
Abstract: The shortage of arable land and shortage of livestock feed are major constraints in East Hararghe Zone. Thus, a field study was conducted to evaluate early maturing sorghum varieties and cowpea varieties intercropping for both food and feed production at Fedis Agricultural Research Center, eastern Ethiopia in 2018 cropping season. With a total of 11 treatments; Two cowpea varieties (9333 and 9334) and three varieties of early maturing sorghum (Teshale, Birhan and Melkam) and their ...
Abstract: This study was conducted at Haramaya University ‘Rare’ research site with an objective to determining the effects of intercropping vetch and harvesting stages on morphological characteristics, dry matter yield and chemical composition of brachiaria grass using a three factor factorial in RCBD with three replications. The three factors were 1) harvesting stages (HS) with five levels: 60, 90 and 120 day, 60 and 90 day of regrowth, 2) five-levels of intercropping: sole basilisk, s...
Abstract: In Ethiopia, potato ranks first among the major tuber crop in the volume of production and consumption. However, the national average yield is 13.8 tons ha-1, which is very low, due to low soil fertility and poor fertilizer management practices. Field experiment was conducted in 2019/2020 main cropping season at Haramaya University research site. The objectives of the experiment were to assess the influences of integrated use of chicken manure and NPS fertilizers on growth, yield c...
