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: 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: In sub-Saharan Africa, plant nutrient deficiency, due to nutrient mining, is a major growth limiting factor for crop production. As a result, some soils become non responsive to Rhizobial inoculation. In an effort to find out possible correction, a field experiment was carried out on-farm, during 2016/17 growing season, at Gondar Zuria woreda in Tsion and Denzaz Kebeles to evaluate the effect of Rhizobium inoculation, S and Zn application on yield and yield parameters, nodulation, ...
Abstract: Potato is an important food security and cash crop in eastern Hararghe Zone. However, the productivity of the crop is constrained by low soil fertility and poor fertilizer management practices. Therefore, a field experiment was conducted at Haramaya watershed in Haramaya District, Eastern Ethiopia; during the 2014 using irrigation. The main objective of the study was to assess the effects of integrated nutrient management on potato growth, yield and yield components and selected ph...
Abstract: The diffusion of agricultural practices is shaped by the relationships among actors in the social systems and this influences the extent of their adoption by the farmers. The objectives of this study were to assess farmers’ social networks and their explicit role in the diffusion and adoption of selected Climate-smart agriculture (CSA) practices in Sheema District of Uganda. The mixed-methods approach including both qualitative and quantitative measurements to contextually collec...
Abstract: The study was conducted to assess dairy production practices, milk composition, and microbial quality of smallholder dairy farms in Kombolcha Woreda, East Hararghe Zone, Oromia Region, Ethiopia. The study was undertaken in purposely selected three rural Kebeles of Kombolcha Woreda (Bilisuma, Tula, and Sibilu) where dairy Farmers from each Kebele were also purposely selected. A sample of households with at least one lactating cow was selected for interview using a simple random samp...
Abstract: The study was conducted to assess the production practices, milk yield and composition, and to identify constraints and opportunities. The study was conducted in urban and peri-urban areas of Debre-Markos, east Gojjam zone. Four kebeles from each production system were randomly selected based on production potential and accessibility. A total of 120 respondents (15 from each kebeles) who owned local and cross breed cows were selected randomly. Data were collected using semi-structu...
Abstract: Bread wheat is one of the major food security crops in Tigray Regional State, northern Ethiopia. However, moisture stress and low soil fertility limits the production of bread wheat in the region. As a result, three field experiments were conducted in Enderta district in the 2013 and 2014 main cropping seasons with four key objectives. 1. To assess the impact of different rates and timing of nitrogen fertilizer application on the yield, quality, and nitrogen use efficiency of bread...
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: Mung bean has become an important cash and food crop in dry land areas of Ethiopia. However, there are no sufficient research information on the nitrogen (N) and phosphorus (P) fertilizers rates for the crop in the study area. Thus, field experiment was conducted to assess the effect of N and P fertilizer rates on the growth, yield components and yield; and to identify economically feasible rates of N and P fertilizers. The experiment was conducted at Nura -Era, Upper Awash under i...
Abstract: A study was conducted to evaluate the effect of substituting different levels of sweet potato tuber meal (SWPTM) for maize on egg production, fertility, hatchability and egg and chick quality of white leghorn chicken at Poultry Farm of Haramaya University. A total of one hundred ninety two (168 hens + 24 cocks) at age of 42 weeks with initial body weight of 997.95g±19.2 (mean ±SD) were randomly distributed into 12 pens each with 14 hens and 2 cocks. The experimental animals in a ...
Abstract: Vegetable export production is a major source of income and contributes to the alleviation of poverty in Kenya. However, emerging....(continue from the attached pdf)
Abstract: The witchweed, Striga hermonthica (Del.) Benth., is a major constraint to maize (Zea mays L.) and sorghum [Sorghum bicolor (L.) Moench] production in sub-Saharan Africa. Intercropping maize and sorghum with desmodium (Desmodium spp.) effectively controls Striga and enhances grain yields. Studies were thus conducted to assess the potential role of intercropping maize and sorghum with different food legumes for control of Striga. Seasonal Striga counts in the intercrops, other than g...
Abstract: Purpose – The adoption of climate-smart agricultural practices (CSAPs) is important for sustaining Indian agriculture in the face of climate change. Despite considerable effort by both national and international agricultural organizations to promote CSAPs in India, adoption of these practices is low. This study aims to examine the elements that affect the likelihood and intensity of adoption of multiple CSAPs in Bihar, India. Design/methodology/approach – The probability and in...
