ABSTRACT Preservation of food is a pre-requisite for food safety and security, bridging the gap between the site of production and site of consumption and the rising between demand and supply. There has been a problem of preserving seasonal food properly and disinfesting food without noticeable hazard to the consumer. There is also a noticeable increase in the incidence of food borne disease. The study is aimed at determine the shelf life extension of avocado, carrot, okra and tomatoes when p...
ABSTRACT Amaranths are African indigenous vegetables (AIVs) that have recently gained importance as a food source in Africa owing to the high nutritional value of their leaves and grains. Production of this crop is, however, limited by arthropod pests especially the lepidopteran leaf-webbers, leaf-worms and stem weevils. The use of insecticides for their management is uneconomical and also present health and environmental concerns. Host plant resistance (HPR) to insects is an effective, econ...

Slenderleaf (Crotalaria brevidens), also known as rattle pod, is a prominent species of Crotalaria used as a vegetable in Kenya. It is a highly nutritious leafy vegetable, good sources of provitamin A, Vitamin C, carotenoids, iron protein, and calcium. At an average of 3 tons per hectare production of slender leaf in Kenya is low compared to an average potential of 11 tons per hectare. Previous studies done evaluated the influence of nitrogenous and phosphoric nutrients on slenderleaf grow...
ABSTRACT The use of quality seed is a prerequisite for high vegetable productivity. The Ghana Seed Inspection Division conducts seed quality assessment to ensure that seeds meet minimum quality standards before they are certified to be sold to farmers. Poor seed storage practices and repackaging of certified seeds at retailers’ end could adversely affect seed quality before farmers purchase these for planting. Post-certification surveillance was undertaken to assess the quality of certified...
Abstract The worldwide increase in aquaculture production and the decrease of wild fish stocks has made the replacement of fish oil (FO) in aquafeed industry a priority. Therefore, the use of terrestrial animal fats and vegetable oils, which has lower cost and larger supplies, may be good as substitute for FO. This study investigate the effects of total replacement of FO by two terrestrial animal fats (pork lard and poultry fat) and three vegetable oils (palm kernel oil, shea butter oil and s...
Abstract One of the major problems facing aquaculture is the inadequate supply of fish oil mostly used for fish feed man- ufacturing. The continued growth in aquaculture production cannot depend on this finite feed resources, therefore, it is imperative that cheap and readily available substitutes that do not compromise fish growth and fillet quality be found. To achieve this, a 12-week feeding trial with Heterobranchus longifilis fed diets differing in lipid source was conducted. Diets were ...
ABSTRACT Organic wastes, such as faecal sludge (FS), cocoa pod husk (CPH) and empty fruit bunch (EFB) abound in large quantities in the Ghanaian environment. They contain considerable amounts of nutrients and organic matter which can be recycled to improve soil organic matter content and boost soil fertility status. This study was conducted to characterize and quantify FS produced in Sekondi Takoradi metropolis (STMA), co-compost FS with EFB and CPH, evaluate the suitability of the co-compo...
ABSTRACT Farmers’ access to relevant and useful agricultural information is key to improving their productivity. Research shows that the information needs of farmers differ and that the behaviour of farmers in seeking information is as varied as their production systems. The study was conducted to identify the information needs and assess the information seeking behaviour of urban vegetable farmers whose activities supplement the food needs of an increasingly urbanised population in sub-Sah...
ABSTRACT Many underutilized indigenous foods contain high levels of essential trace elements some of which have immunological effect, and play important roles in many metabolic and enzymatic functions in man. Such elements include zinc, vanadium, selenium, chromium and iodine among others. If sustainably exploited, they would cost-effectively promote good health and thus reduce the medical bills. There is need therefore to analyze for these essential trace elements in foods, and especially t...
ABSTRACTThe study on bioaccumulation of lead and cadmium from contaminated soil into Amaranthus hybridus grown in irrigation farm lands in zaria, Kaduna state, Nigeria was carried out to assess the risk to human health by heavy metals (Pb and Cd) through the intake of grown vegetables (Amaranthus hybridus) from bomo lake, river galma and borehole water irrigated site. The samples collected (A. hybridus and soil) were separately digested and the heavy metals were analyzed using Atomic absorpti...
Abstract: We utilized data from cereal, legume, and vegetable growers in Kenya and Uganda to assess their knowledge and management practices of common pests and willingness to pay (WTP) for biopesticides. The contingent valuation method was used to assess the WTP and associated factors among 600 and 700 farmers in Kenya and Uganda, respectively. Fall armyworm (Spodoptera frugiperda) was reported as the major maize pest in both countries, while aphids (Aphis spp.) and Tuta absoluta were ranke...
ABSRACT Fresh samples of vegetable salad collected from different food outlet in Ilorin metropolis were evaluated for bacteria loads, at a temperature of 250c and the PH of the samples which is 3.7 using spread plate agar dilution method, the bacteria load ranges from 1.6x104cfu/g to 11.5x104cfu/g and faecal coliform ranges from 1.6x104cfu/g to 4.6x104cfu/g associated with the salad from majority of the samples. Microorganism associated with vegetable salad include,Bacillus anthracis mycobact...
