Abstract: This study was conducted to assessing of selected heavy metals (Cr., Cd, Zn, Hg and Pb) accumulation in the edible portions of cabbage, tomato and onion cultivated around Wonji in eastern part of Ethiopia. The concentrations of the same heavy metals were determined in water samples collected directly from industry discharge and also three irrigation sites Varied between sampling points. Vegetable Samples were first optimized through wet digestion procedure and contents of heavy met...
ABSTRACT Vegetables are the edible parts of plant that are consumed wholly or in parts, raw or cooked as part of main dish or salad. A vegetable includes leaves, stems, roots, flowers, seed, fruits, bulbs, tubers and fungi (Uzo, 1999). Vegetables are good sources of oil, carbohydrates, minerals and vitamins depending on the vegetable consumed (Ihekoronye & Ngoddy, 2000). (Ononugbu, 2002) reported that vegetable fats and oil lower blood lipids thereby reducing the occurrence of disease ass...
The greenhouse technology is a booming segment of agriculture in the world, because it offers a favorable climate conditions which increase plants growth as the plants are grown in a controlled environment. This research assessed the present conditions of the Controlled Environment Agriculture (CEA) in Ghana and emphasized on issues that are paramount to Greenhouse vegetable production effectiveness. The general objective was to evaluate the current status for greenhouses in Ghana and p...
ABSTRACT There is growing awareness about the efficacy of essential elements in the maintenance of good health and prevention of diseases. Zinc plays a vital role in wound healing, immune system, reproductive system and nervous system. Zinc wades off oxygen free radicals and also aid in metabolism of carbohydrates by assisting insulin to function. Chromium lowers blood sugar and also works with insulin in metabolization of sugar, while copper is required for conversion of body’s Fe into ha...
ABSTRACT Vegetable production is one of the economic activities of farmers in the Northern Region of Ghana. It is an income generating activity from which most farmers meet their livelihood outcomes. Despite the fact that some of the vegetable farmers receive extension services from MoFA Agriculture Extension Agents with the expectations that yields of their vegetable would increase and their livelihood outcomes would have improved, the farmers still record low yields. This study therefore ai...
Abstract: Shortage of water for agriculture has resulted in the need to explore the use of wastewater for irrigation, however this can pose a health problem to the people emanating from the produced food as a result of the accumulation of pollutants. The purpose of this research was to investigate the accumulation of some heavy metals and bacteriological indicators in the different parts of spinach vegetable irrigated with secondary wastewater effluent treated through a pilot filtration syst...
ABSTRACT Energy and exergy analysis was conducted for a vegetable oil refinery in the Southwest of Nigeria. The plant, powered by two boilers and a 500 kVA generator, refines 100 tonnes of crude palm kernel oil (CPKO) into edible vegetable oil per day. The production system consists of four main group operations: neutralizer, bleacher, filter, and deodorizer. The performance of the plant was evaluated by considering energy and exergy losses of each unit operation of the production process. Th...
ABSTRACT Commonly sold vegetables within the Abuja Municipal Area Council, FCT Abuja were investigated for the prevalence of parasitic eggs. A total of 225 vegetable samples were collected and investigated for the presence of these parasites using standard methods, and quite a number of them were positive. Results obtained showed the parasitic infestation rates were 71.11%, 71.11%, 68.89%, 55.55% and 20% for water leaf, green, pumpkin, lettuce and carrot respectively. The parasites encountere...
Abstract Soil contamination with heavy metal due to discharge of untreated or incompletely treated industrial effluent is a threat to the ecosystem and human well-being. The effect of textile waste effluent on four vegetable plants (Corchorous olitorius, Telfairia occidentalis, Celosia argentea and Amaranthus hybridus) cultivated within farmlands located along the Abuja River in Ibeshe town near Ikorodu, Lagos State was investigated. Their heavy metal levels were determined using atomic abso...
One of the most critical inputs to vegetable (fruits) production in semi-arid areas, dry season farming and nursery establishment is water. During the dry season or off season, the source of water for vegetable growing is from irrigation while in the wet season, rainfall is the source of water. Young vegetable seedlings in the nursery or in the field should be watered in the early morning or in the evening. Watering should be done before transplanting particularly in the evening. Over-wa...
ABSTRACT Effects of climate change on the yield reduction and prediction of vegetable crop was carried out using CROPWAT 8 with irrigation scheduling condition; critical depletion at a water application depth of 2mm, definite interval of 3days at a depth of 2mm and no irrigation.
ABSTRACT This study was carried out to isolate, characterize and identify Aeromonas spp. from Irrigation water and vegetables. Water and vegetable samples were collected and analyzed for physicochemical and microbiological analysis. Physicochemical parameters such as pH, Temperature, Total Dissolved Solid (TDS), Dissolved Oxygen and Biological Oxygen Demand were determined using standard methods for water samples only. Microbiological parameters such as Total Coliform count (TC), Faecal ...
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: Nitrogen (N) deficit is one of the limiting factors to food security in most developing countries while the excessive use of N has resulted in environmental contamination. Timely N availability, at the right rate is crucial to improving crop yield and N use efficiency in farming systems. Therefore, understanding nitrogen dynamics under different farming systems is essential to improve N use and recovery efficiencies of crops and in addressing environmental impacts associated with i...
ABSTRACT The study investigated the nutrients and phytochemical compositions of some leafy vegetables in Nigeria (Hibiscus cannabinus, Adansonia digitata, Sesamum indicum and Cassia tora leaves) and the effects of their extracts on blood glucose and lipid profile of alloxan induced diabetic rats. Two kilogrammes of each of the vegetables were bought fresh, sorted by removing extraneous material, washed with deionized water and separately pulverized using Gallenkamp mixer Kenwood –MPR 201. A...
