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: Low soil fertility and poor crop management practices including 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 blended fertilizer (NPS) on growth, yield components and yield of bread wheat and to identify economicaly feasible rates of seed and blended NPS in the study area. Factorial combinati...
Abstract: A study was conducted to evaluate the effect of substituting maize with different levels of taro tuber meal (TTM) on feed intake, weight change, feed conversion ratio, mortality percentage, carcass characteristics and partial budget analysis of broiler birds. Four experimental diets were formulated with T1 (control) containing 0% TTM while diets T2, T3 and T4 contained (TTM) each at 20%, 40% and 60% replacement levels respectively. Two hundred sixteen unsexed blood Cobb 500 broiler...
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...
Abstract: Evaluation of two microbial agents, Trichoderma asperellum and Bacillus subtilis and fungicide Linkimil 72 WP against rice blast disease, Pyricularia oryzae were done in a laboratory and pot experiment. Dual inoculation of T. asperellum, B. subtilis and Linkimil 72 WP caused significant inhibition of radial growth of P. oryzae. Both T. asperellum and B. subtilis showed over 75% inhibition of radial growth (PIRG) compared to Linkimil 72 WP with PIRG range of 21-23 % and control with...
Abstract: The objective of this paper was to investigate farmers’ knowledge and management of rice blast disease in Tanzania. Farmers’ household survey was conducted in five districts namely Mvomero, Morogoro rural, Ulanga, Korogwe and Muheza in April and May 2017. Data were collected through face-to-face interviews using semi-structured questionnaire and observations made through transect walks across selected villages. Farmers observed symptoms of rice blast disease for the first time ...
Abstract: Understanding farm diversity is essential to delineate recommendation domains for new technologies, but diversity is a subjective concept, and can be described differently depending on the way it is perceived. Historically, new technologies have been targeted primarily based on agro-ecological conditions, largely ignoring socioeconomic conditions. Based on 273 farm households' surveys in Ethiopia, we compare two approaches for the delineation of farm type recommendation domains for...
Abstract: International crop exchange always brings the risk of introducing pests to countries where they are not yet present. The invasive pest Tuta absoluta (Meyrick 1917), after taking just a decade (2008–2017) to invade the entire Africa continent, is now continuing its expansion in Asia. From its first detection in Turkey (2009), the pest has extended its range of invasion at a very high speed of progression to the southeast part of Asia. This study adopted the cellular automata model...
