ABSTRACT Population growth, shortage of food due to unpredicted weather coupled with HIV/AIDS has increased nutritional deficiencies in people living in developing world. Use of micronutrients presents a low-cost strategy for achieving large reductions in death caused by malnutrition. The indigenous green leafy vegetables are of much importance among food crops as they provide adequate amounts of vitamins, immune boosting trace elements and anti-oxidants. The nutritional value of the indigeno...
Abstract: The use of wastewater to produce food crops particularly vegetables is very prevalent within and outside the urban centers of developing countries. In the capital city of Ethiopia, Addis Ababa, where irrigation water for cultivation of vegetables is commonly derived from the polluted Akaki River, the practice has often been blamed for causing negative externalities to public health and the environment. To address these issues, the studies of this doctoral dissertation mainly focuse...
ABSTRACT Consumption of vegetables is the most sustainable way of reducing and controlling micronutrient deficiencies in resource-poor communities. However, not much has been documented about standard recipes that are of high nutritional quality in terms of minerals and vitamins. The aim of this study was to modify traditional cowpea leaf vegetable preparation methods to enhance carotenoid retention and iron bioavailability. Modification principles included reducing cooking time, addition of...
ABSTRACT This study sought to assess the knowledge of consumers on the safety of vegetables produced in Morogoro Urban using Low Quality Water (LQW). The study determined how the knowledge of consumers influenced the perception and preference of various types of vegetables irrigated with LQW. A cross sectional study design was adopted and the 130 respondents were selected using simple random and purposive sampling techniques. Data collection was done using an interview schedule, focus group d...
ABSTRACT The content of nitrate, nitrite and Vitamin C in eleven samples of fresh vegetables were determined. The levels of nitrate were beyond here on recommended in six of the vegetables, namely: Celosia sp. Lactuca, sativa , Amaranthus hybridus, Brassica oleracea variety acephala, Talinum sp, Spinacia oleracea. Minute quantifies of nitrite were detected in Celosia sp and Daucus carota. With accompanying high concentration of Vitamin C (a reducing agent) present in Celosia sp. this vegetabl...
Abstract: One health’ (OH) is a cross-sectoral approach that addresses human, plant, animal, and environmental health problems. The initiative stems from recognition of the convoluted linkages among global health risks and the need for coherent multipronged countermeasures. For agriculture, environmental degradation and biodiversity depletion wrought by heavy reliance on inorganic inputs to meet the needs of the ever-growing human population, are a matter of societal concern. Agroecologica...
ABSTRACT In an attempt to facilitate the processing of vegetable material which is a daily nutritional food requirement of man, a vegetable slicing machine has been developed. This paper therefore presents the developmerit of a vegeuble slicing machine which is a mechantcat device that is used for slicing vegetable materials instead of the cnlde cumbersome and unhygienic method of manual slicing of vegetable materials. l*he dwdoped machine consists ofthe hopper, the cutter housing, the cuttin...
Abstract: Overuse of pesticides in vegetables and related fresh products raises serious public health concerns. However, the recognition and assessment of the magnitude of public health risk remains a low priority in low income African communities. Brassicas are a cosmopolitan crop in African horticulture, and equally so, is the major economic pest, the diamondback moth, Plutella xylostella (L.). In consequence, insecticide use on P. xylostella in brassica production systems presents persist...
Abstract Vegetables are grown for human consumption all over the world. Indigenous Leafy Vegetables (ILV), both wild and domesticated species make important contributions to household improvement in Nigeria. However, information on availability of these species in the market and the consumption level at household is limited. Therefore, ILV species in southeastern Nigeria were investigated in order to determine their availability and consumption level. Multi-stage random sampling procedure w...
ABSTRACT Commercialization has potential of enabling rural households to advance in vegetable production through better access to financial services, and enriched market coordination and participation. In recent years, there have been efforts to boost vegetable commercialization particularly among smallholder female farmers in Kilifi County. Since risk attitudes vary from male to female farmers, the differences in risks and risk perceptions of farmers may in part explain the unwillingness of ...

ABSTRACT A cross-sectional study was carried out in Mang’ola area in Lake Eyasi basin from October 2012 to February 2013 to assess pesticide exposure pathways to vegetable growers and consumers. A total sample size of 263 respondents was selected for the study. Baseline data for exposure pathway scenario, eating habits and quantities of vegetables consumed were collected using structured questionnaires, In-depth interview, Focus group discussion and observations. Health risk characterizatio...
Abstract: This study investigates the effect of transaction cost on participation of smallholder farmers in vegetable market and on market channel choice decisions. The empirical analysis was based on primary data collected from 250 sample farm households located in the Central Rift Valley of Ethiopia in 2017. The double hurdle model estimation results show that age, total land size, and distance from asphalt road negatively influenced farmers decision to participate in vegetable marketing. ...

ABSTRACT This study was conducted on urban vegetable farming sites at Mzumbe, Mafisa and Fungafunga in Morogoro municipality-Tanzania. The objective of this study was to investigate the effect of Commiphora swynnertonii resin extract against helminths eggs/larvae isolated from low quality water and vegetables at Mzumbe, Mafisa and Fungafunga in Morogoro municipality. A total of 90 vegetable samples and 70 water samples (30 treated, 30 river water and 10 untreated) were collected from the stu...
