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...
Abstract: Pectinases are the group of enzymes that degrade pectin. This study was conducted with the aim of isolation of efficient pectinase producing pectinoloytic fungi from the decaying vegetable and fruit soil containing decomposing mango peels using extracted mango peels pectin as a growth substrate under submerged fermentation, determining optimum pectinase production conditions and characterizing of ammonium sulphate precipitated pectinase activity with regards to some physicochemical...
ABSTRACT The use of chemical fertilizers to replenish depleted soil nutrients due to over cultivation and erosion is a common practice. Natural radionuclides in these fertilizers can cause some radiological adverse health effects to animal, through indirect ingestion of fertilizer, including consumption of plants grown with fertilizers. Information on the level of contribution of chemical fertilizers to farm soil radioactivity and radiological health effects in Nigeria are scanty. This study ...
This study discovered that infiltration rate, bulk density, pH and available phosphorous were the most sensitive soil properties for use as MDS indicators for vegetable fields at south western of Nigeria. The study also revealed that both the MDS indicators and SQI value obtained were influenced by biofertilzer-fortified compost application and would serve as vital instrument for evaluating soil fe...
Diabetes mellitus is a chronic disease condition that is ravaging the populace today, including Delta State of Nigeria. Dietary habits are implicated in glycaemic control, while a strong network of peer-support has positive impact on self-management behaviour. However, neither diabetes food menu plans nor peer-support network is known to exist in Delta State public health facilities. The objective of this study is development and evaluation purposes. First is to develop pictographs of indigen...
ABSTRACT Consumption of Indigenous vegetables (IVs) in most Sub-Sahara African countries including Tanzania is replaced by exotic varieties/species, regardless of their potential nutritional and economic values. Given this situation, among other IVs, this study was conducted with the aim of assessing consumers‟ acceptance and willingness to pay (WTP) for processed cassava leaves products. Sensory test together with a consumer survey of 110 randomly selected respondents was conducted in Moro...
This study discovered indigenous rhizobacteria (A. brasiliense, A. chrocoocum, P. stutzeri and P. putida) from the rhizosphere of vegetable crops in semi-arid agro-zone of Rajasthan desert capable of synthesizing phytohormone. This study will provide baseline information on the phytohormone biosynthesis profile of t he isolates and the phytohormone produced can be transformed into commercial bio-formulations f...
Abstract: Water is scarce resource in Central Rift Valley of Ethiopia and is major limiting factor for crop production. Onion is one of the major economically important vegetable crops grown under irrigation in central rift valley. The field experiment was conducted at Melkasa agricultural research center during the off-season to identify irrigation method and irrigation application level that maximizes productivity of onion per unit of water consumed and enhanced onion crop production. The ...
Abstract: Carrot (Daucus carota subsp. sativus) is an important vegetable crop in Ethiopia. In many areas of the country, the rain fed season constitutes much of the area under carrot production. Despite areas increase, the productivity and production is much lower in the country. Optimum nutrient management and inappropriate plant population are some of the major yield limiting factors for successful carrot production. Northeastern Ethiopia has suitable agro-climatic condition for carrot pr...
