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...
A BSTR A C T To enhance food security, crop losses due to disease and pest damage must be reduced. Improved technologies for pest control using appropriate and environmentally sound technologies to promote food security is a major priority for many developing nations. Integrated Pest Management, IPM (also referred to as Integrated Crop M anagement (ICM)) is one o f such approaches to promoting food security. Its adoption by farmers is therefore critical. In Ghana, few empirical evidence about...
ABSTRACT The concentrations of some trace metals (zinc, iron, copper, cadmium and lead) in 51 canned foods (fish, vegetable and fruit juice) samples purchased within Abuja Municipal Area Council (Nigeria) were determined using the flame atomic absorption spectrophotometry (FAAS). The wet oxidation procedure of HN03-H20 2 was used in the preparation of the samples. The ranges obtained for trace metals analyzed in ug/g are as follows: Canned fish: Zn (19.15±0.8-32.50±0.3), Fe (17.92± 1.2 --...
ABSTRACTA portable cold room storage was developed. The system was tested with different types of perishable crops under different temperatures. The system is made up of two units, one, the evaporating unit that is where the produce was stored; it is made up of steel material with 79mm by 45mm in length and breadth. While the second unit is the trolleys, the system consists of a control switch that is calibrated to suit any type of produce stored in the system. It contain a separate basemen...
ABSTRACT Tomato (Solanum lycopersicum L.) is a major vegetable crops, and is ranked second at 14% of total value of exotic vegetables produced in Kenya after potato with a value of 55%. It is predominantly grown by small to medium scale growers in open fields. However, open field tomato production faces many challenges including weather extremes, diseases and insect pests. The whitefly (Bemisia tabaci Gennadius), is one of the major pests of tomato capable of causing up to 80% loss in yield....
Abstract: A green prospective based on the reuse of waste materials such as beef tallow and waste cooking vegetable oils to manufacture soap is presented. Beef tallow and waste cooking oils that is discarded as waste from households and restaurants after frying is reviewed for the production of toilet (bath) soap. The discarded oil is purified with a brine solution and bleached with Hydrogen Peroxide (H2O2.) Purified waste cooking oils and beef tallow is mixed with coconut oil commonly used ...
