ABSTRACT Water scarcity is globally getting worse in the light of increase in demand for water use. Human and ecosystem health and economic development are affected by problems of water scarcity and water pollution. This study was carried out to assess the current net benefit of water resource in different land uses around the Kilombero Valley Ramsar Site in Tanzania. Specifically the study was conducted to identify different land uses related to water, to determine and estimate costs and be...
Abstract/Overview The perception of African nightshades ( Solanum section Solanum ) as “healthy” foods, supported by documentation of their high nutri- tional and medicinal benefits, has led to a sudden and steady upsurge in their consumption, demand and monetary value in Africa and most parts of South-East Asia. However, due to very low leaf yields, production of these vegetables remains on small-scales, re sulting in acute shortages and escalating prices, especially in urban areas. ...
Abstract: Transaction costs are pervasive barriers in agricultural supply chains as they exclude farmers from profitable markets. Identification of these costs without reliance on proxy variables and their effects on smallholder profitability has not been empirically analyzed. The Heckman 2-step model was used to assess the effects of magnitudes of these costs on farmer profitability. Indirect monitoring and negotiation-related transaction costs had significant, positive, association with se...
ABSTRACT A study was conducted to assess the extent of community participation in solid waste management (SWM) in Mbeya City, Tanzania. Data were collected using both structured and non-structured interviews. Field observations and secondary data supplemented the data collected using questionnaires. Purposive sampling procedures were used to obtain three representative wards. At ward level, 60 respondents each from different households were picked at random for the study leading to a sample...
This seminar report provides an in-depth examination of the microorganisms causing soft rot of tomato. Tomato (Solanum lycopersicum) is a red edible fruit having many varieties which are widely grown, often in greenhouses in cooler climates and open fields. It is consumed in diverse ways, including raw, as an ingredient in many dishes and sauces, in drinks and as a vegetable for culinary purposes. Diseases are a major limiting factor for tomato production. Diseases can be classified into two ...
ABSTRACT The ultimate goal of the study is to assess the crumbled feed technology with respect to its contribution in cost savings in per unit cost of production in broiler via a field experiment. The experiment was carried out using 294 broiler day-old-chicks divided into two groups; control and treatment, with three replications each. Each replication consisted of 49 birds. The experiment was carried out for six weeks, which means two weeks saved from the actual 8 weeks farmers keep the bir...
Abstract: Lettuce (Lactuca sativa L.) is one of the most popular leafy salad vegetables for fresh consumption and containhealth-promoting compounds.Hydroponic method is a techniques of cultivation plants using bioorganic liquid fertilizer without soil and is more important than soil because of efficient resourcesmanagement and quality food production. This study,wasaimed to produce bioorganic liquid fertilizer from fermented of fresh chicken manure and onion peels that can be used for hydrop...
ABSTRACT The important contribution of Women in the Northern Region of Ghana to Agricultural Production, processing and marketing cannot be overlooked. Available data and personal observation show that women do most of the work on the farm. Women in direct food production either help their husbands on the farm or are themselves owners of farms. Farm activities (such as planting, weeding, fertilizer application, threshing and storage) are done by women. In addition, they are responsible for ...
ABSTRACT The purpose of this project was to study the antioxidant potential of selected Namibian Leafy Vegetables (NLV), using Total Phenolic Content (TPC), Total Flavonoid contents (TFC) as well as Diphenyl-1-picrylhydrazyl (DPPH), 2,2-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS), and Reducing Power (RP) assays. The study also aimed at detecting and characterizing eight phenolic acids (4- hydroxybenzoic, trans-ferulic, vanillic, gallic, syringic, sinapic and para-coumaric acids) ...
Abstract This study compares the response of Amaranthus candatus vegetable to root-to-shoot signals of soil drying and assesses applicability of the use of partial root zone drying (PRD) technique in increasing water-use efficiency. From a completely block randomized design, seeds were grown on three plots with each having three replicates. Three treatments were compared: half of the root system watered and half droughted by delivering 50% less crop water requirement (CWR) per irrigation dep...
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous organic pollutants in urban environmentsincluding urban soils. Elevated concentrations of PAHs in urban soils are caused by incomplete combustion of petroleum and coal. This study assesses 16 individual PAH compounds in a total of 112 surficial soil samples. The objective was to assess and compare the levels of contamination as well as examine the main sources of PAHs in four urban agricultural soils using molecular ratios of some specifi...
The results found in this study have implications for local Nigerian food producers, retailers, other participants of the food sector, and government food policy makers. In this thesis the demand analysis for onion, peppers, fresh okra and tomato in Nigeria was conducted using General Household Survey data collected by the World Bank and the Nigeria National Bureau of Statistics. The two stage estimation procedure and Linear Approximation Almost Ideal Demand System addressing censoring were ...
ABSTRACT Fresh healthy carrot promote good health but harbour a wide range of contaminants. To assess the microbial quality of carrots sold in Ibadan, a total of fifteen samples were purchased from five vendors. Samples were analyzed to study the density of microorganisms by standard plate count. ...
ABSTRACT Botswana is classified as an upper middle income country and despite having attained such economic growth, the country still faces socio-economic challenges such as poverty. The current poverty rate is 20.7% while rural poverty is 24.7% which is relatively higher for an upper middle income country. In order to address this problem, the government introduced the Poverty Eradication Programme. This study therefore, sought to assess the income, expenditure and consumption dimensions of ...
Abstract Worldwide, commercial production of French bean (Phaseolus vulgaris L.) is constrained by diseases, key among them being the bean common mosaic virus (BCMV) and bean common mosaic necrosis virus (BCMNV). These potyviruses are the most devastating to common bean farmers and can cause total yield loss under heavy infestation. The objective of this study was to characterize the BCMNV resistance in commercial French bean cultivars and initiate a breeding program against the disease. A s...
