Abstract: Common bean is one of the most important food and export pulse crop in Ethiopia. However, its yield is limited by a number of constraints, which include poor agronomic practices such as low soil fertility management, inappropriate plant spacing, low and erratic rainfall and diseases. Hence, a field experiment was conducted at Yabelo during the 2018-2019 main cropping seasons to assess effect of rates of NPS fertilizer and inter row spacing on growth, yield components and yield of c...
Abstract: Use of appropriate verities and balanced fertilizer recommendation are important agronomic practices used to increase the productivity and quality of bread wheat. Hence, field experiment was carried out to assess the effect of NPS fertilizer rates on yield related traits, yield and grain protein of bread wheat varieties and to determine economically feasible NPS fertilizer rate for bread wheat production. The treatments consisted of five levels of NPS (0, 50, 100, 150 and 200 kg ha...
Abstract: Hot pepper is an important spice and vegetable crop in Assosa, western Ethiopia, however, its production is low due to several constraints of which low accessibility of improved varieties and poor cultural practices including soil fertility management. This research was conducted to asses the effect of blended NPS fertilizer on yield related and, green pod yield of hot pepper varieties and estimate cost-benefit of blended NPS fertilizer rates for hot pepper production. The research...
Abstract: Potato is one of food and cash crop in Debre Libaanos District of central highlands of Ethiopia. However, the yield of the crop is low due to various constraints of which poor soil fertility and lack of proper plant spacing recommendation specific to the District. Therefore, a field experiment was conducted to asses’ effects of blended NPSB fertilizer rates and intra-row spacing on yield and yield related traits of potato and to estimate cost-benefit of NPSB fertilizer for potato...
Abstract: The study was conducted to determine the major honeybee diseases and pests in selected districts of Amhara Region in harvesting, dearth, and rainy seasons from November 2017 to August 2018. In total, 276 (201 adult bees and 75 brood) samples were diagnosed for honeybee diseases and pests. The prevalence rate, basic risk factors, and the severity of honeybee diseases and pests were analyzed using descriptive statistics, chi-square and univariate logistic regression with the aid of S...
Abstract: Common bean is one of the most economically important pulse crops cultivated in eastern Ethiopia. However, its average yield reported at national level remains far below the potential yield to be attained. This is partly due to low soil fertility management and inappropriate agronomic packages. Hence, this experiment was conducted to assess the effect of phosphorous rates on growth, yield and yield components of improved common bean varieties and to estimate the cost benefit of Pho...
Abstract: his study was designed to assess smallholder butter value chain and to evaluate microbial qualities and hygienic practices of handling raw milk, fermented milk (Irgo) and butter in eight selected dairy potential areas of the Ethiopian central highlands. A total of 448 respondents comprising 320 smallholder farmers, 80 open market butter traders, 40 dairy product shops and 8 primary dairy cooperatives were interviewed using a semi-structured questionnaire. From a subset of the surve...
Abstract: Common bean production is constrained partly due to lack of recommendation on the optimum plant density and rate of phosphorus fertilizer. In view of this, a field experiment was conducted in Dangur district during 2016 cropping season to determine the effect of phosphorus rate and plant density on yield related traits and yield of common bean. The experiment consisted of five level of phosphorus (0, 23, 46, 69 and 92 kg P2O5 ha-1) and four levels of plant densities (333333, 250000...
Abstract: The study was conducted in Selected Districts of Sidama zone with the objective to assess the production practices, productive and reproductive performance, on farm evaluation of milk production performance, and chemical composition of milk of Local cows, and to identify their constraints and opportunities. For study, multistage sampling was employed in that three districts were selected representing Highland (Wonisho), Midland (Dale) and Lowland (Loka Abaya) from Sidama Zone and t...
Abstract: One of the reasons of low yield of chickpea in Ethiopia is the use of inappropriate plant population by farmers. Thus, field experiment was conducted to assess the effect of inter and intra-row spacing on yield and yield components of chickpea cultivars in Mertulemariam, Northwestern Ethiopia. The treatment consists of two chickpea cultivars (one Kabuli type, Arertie; one Dessi type, local), three inter-row spacing (40, 30and 20 cm) and three intra-row spacing (20, 15 and 10 cm). R...
Abstract: Soil acidity and poor soil fertility are the major soil chemical constraints which limit crop productivity in western Ethiopia. These low productivity in leguminous crops are as a result of declining soil fertility and reduced N2-fixation due to biological and environmental factors. Thus, study was carried out to determine the influence of lime, Bradyrhizobium inoculation and phosphorus fertilizer on soybean nodulation, yield components and yields; and to identify economically feas...
Abstract: Garlic (Allium sativum L.) is an important cash and spice crop produced for home consumption and as a source of income to many smallholder farmers in many parts of the Ethiopia. However, the yield of the crop is often constrained by low and imbalanced nutrient supply in the soil. Therefore, a field experiment was conducted at Adet Agricultural Research Center, Koga irrigation trial site in 2015/2016 cropping season with the objectives of assessing the effects of combined applicatio...
Abstract: Common bean production is severely infested by weeds in Wolaita Zone, Southern Ethiopia. Field experiment was conducted to assess the integrated effect of different weed management practices and herbicides on the growth and yield of common bean and to evaluate the economic feasibility of weed management practices in common bean in 2014 at Wolaita Sodo. The experiment comprises of fifteen treatments which included two herbicides (s-metolachlor and pendimethalin) applied as pre-emerg...
Abstract: Optimum plant spacing and number of seedlings per hill are important agronomic practices for the productivity of rice. Hence, field experiment was carried out to assess the effect of plant spacing and number of seedlings per hill on yield components and yield of transplanted rice under irrigation at Werer, Middle Awash. Factorial combinations of 2 inter-row spacing (20 cm and 30 cm), 3 intra-row spacing (10 cm, 15 cm and 20 cm) and 3 seedlings (2, 3 and 4) per hill were laid out in...
Abstract: Cabbage (Brassica oleracea L.) is a member of the cole crops, and it is an important fresh and processing vegetable crop in most of the countries of the world. However, yield of the crop is often constrained by low and imbalanced nutrient supply in the country at large and in Gudji Zone in particular. Therefore, this study was conducted at the Bore Agricultural Research Center (BoARC) during the period from July 1, 2014 to December 2, 2014 main cropping season to assess the effects...
