Item Genetic characterization of Biochemical contents of pigeon pea (cajanus cajan millsp)(Emerald Group Publishing Limited, 2009) Akande, S. R.; Balogun, M. O.Purpose – The purpose of this paper is to characterize 25 collections of pigeon pea from south-west Nigeria using nutritional and anti-nutritional contents of the seeds. Design/methodology/approach – The nutritional and anti-nutritional constituents of 25 collections of pigeon pea were determined. Data collected were subjected to correlation, principal components and fastclus analyses. Findings – Ariation among the collections for the nutrient contents was low. Trypsin inhibitor content had the highest variability ranging between 21.74 and 35.43 Tiu/mg. Protein and trypsin inhibitor contents were significant and negatively correlated. The first three principal components explained 74.0 per cent of the total variation. Fastclus procedures grouped the collections into three. Members of cluster 1 had the highest value for protein and the lowest concentrations of the antinutritional factors (ANFs). Cluster 2 possessed relatively low protein with high level of ANFs while cluster 3 was intermediate between clusters 1 and 2 for most characters. Originality/value – The results indicate that members of cluster 1 with high protein and low levels of ANFs are good candidates in breeding/selecting pigeon pea cultivars with enhanced nutritional valuesItem Presence of hydrocarbons and heavy metals in some fish species in the cross river, Nigeria.(2004) Olaifa, F. E.; Ayodele, I. A.The study was undertaken to determine the total hydrocarbon (THC) and heavy metal contents of fish (finfish and shelf fish) in the cross river, Nigeria. Fish samples were collected in the dry (March) and rainy (October) seasons between 2000-2002. The finfish species identified in the study were Synodontis clarias, Sarotherodon galilaeus, Heterotis niloticus, Scholbe mystus, ansorgil and the shelfish were macrobrachium vollenhovonii and tympanotnomus luscalus. Significant difference (P<0.05) existed between finfish andshellfish in both THC and heavy metals contents. The levels of THC in fish exceeded the World Health Organization's limit of 0.0001 ppm by an average of 3.2 and 15.57 mg/kg in fin and shelffish respectively. High concerntrations of vanadium and THC in fish samples were the main indicators of pollution from petroleum sourcesItem Vegetable farmers' perception of wastewater use in Ojoo Local Government Area (LGA) of Lagos State(2009-01) Fawole, O. P.In Nigeria, as in many other countries, wastewater use in agricultural production by farming households is on the rise and there is a need to draw the attention of key players and urban authorities in fostering appropriate planning initiatives. For this reason, the perception and knowledge of vegetable farmers becomes necessary to improve their production activities and yield. While previous studies have confirmed limited or no awareness information and education to vegetable farmers that engage in wastewater dependent activities there has been less attention to the perception and knowledge of vegetable farmers' use of wastewater. The purpose of this study was to examine wastewater use in vegetable production as perceived by 200 randomly selected farmers in Ojoo LGA in Lagos State. Results indicate significant relationship between farmers' perception and knowledge of wastewater use across 32 perceptual and 22 knowledge dimensions. Respondents' have high perception (96.3%) and knowledge (53.0%) of wastewater use in vegetable production. Regular challenges experienced by these farmers are environmental pollution, fire and disease outbreaks, disputes, and pest infestation while occasional ones include drought, erosion, flood, climatic fluctuations, and unstable market prices.Item Framing of environmental stories in two Nigerian daily newspapers(2009-01) Fawole, O. P.The environment has major impact on the economic, social, cultural and ecological activities of man. Through framing analysis (Inter-coder Reliability Coefficient=.95), this study examined 36 stories each from the Punch and Nigerian Tribune daily newspapers from January 1 through December 31, 2008, to uncover how environmental issues were framed. This was done by investigating what these newspapers emphasized, information sources relied upon, and the slant and frames used in reporting environmental stories. Results indicated that majority (52.8%) of the. headlines were presented from the negative perspective. Victims/eye-witness (Nigerian Tribune=59.5%, Punch=40.5%) were relied upon more than government officials (Punch=60%, Nigerian Tribune=40%) as information sources. The disaster frame (33%) was the most frequently used frame in reported environmental stories as posing high risk to agriculture and humans among the five frames (awareness/campaign = 27.7%, assistance =18.0%, warning/blame = 13.9%, responsibility = 9.7%) that emerged from this study. Overall, environmental issues were presented from the negative perspective, and capable of causing uncertainty and fear among lay public and farmers. The reading audience will continue to lack accurate knowledge and understanding of environment as it relates to agriculture and other economic activities, if journalists continue to cover environmental news that is problematic or associated with risk factors.Item Rural women lifestyles: lessons from Nigeria(Society for the Psychological Study of Social Issues C/O Department of Psychology, University of lbadan, 2009-09) Fawole, O. P.Rural women's involvement in family life, social and economic development is growing following efforts to empower them. Efforts of foreign donor agencies, federal and state governments to ensure household food security and reduce poverty have been to establish development initiatives that will ensure rural women's full participation in development. However, most development activities have recorded low rural women's participation. The response of the research community to this low participation of rural women in development activities calls for the documentation of their social and economic activities. This will increase their participation in development activities and enhance gender mainstreaming in the development process. Also, major development initiatives have failed to recognise variations that exist in rural women situations. This study therefore, investigated the lifestyles of rural women in Nigeria using a cross sectional survey. Results indicated that the women surveyed are mostly married, have average age and family size, low education, poor income base and practice a mix of religions. Also results indicated choices, modes and preference in their activities. These are all important variables, which will guide planning and execution of development initiatives and activities and appropriate technologies for rural women in Nigeria.Item Pineapple farmers’ information sources and usage in Nigeria(Agricultural Academy, Bulgaria, 2008) Fawole, O. P.Pineapple farmers’ access to and use of information have great income generation potentials for farmers, expansion of local industries and foreign exchange earnings for Nigeria This study, thus investigated farmers' information sources and usage. Interview schedule was used to collect data from 119 respondents which constituted 27% of all pineapple farmers in the study area. Results show respondents were mostly male (60%), married (66%), with one form of education or another (X = 3.09, SD = 1.46), and aged 28 years and above (71%). Relationships exist between respondents' selected personal characteristics and information sources and usage, years of farming and farming activities challenges. Pineapple farmers will source and use information from easily available and accessible sources such as radio and newspaper. Improving the knowledge base of farmers' will facilitate information sharing amongst them. Research and extension should therefore develop contents in both radio and newspapers that will expand farmers' knowledge base and practical skills for improved pineapple production.Item Urban-rural differential in food consumption in Nigeria: A case study of Ilesa and Atakumosa LGAs of Osun state(Taylor & Francis, 2006) Ajewole, O. I.; Omonona, B. TThis study focused on the differential in food consumption between urban and rural households in Osun State, Nigeria. The data used in the study were obtained through the use of a structured questionnaire administered to randomly selected food consuming households in the Ilesa and Atakumosa local government areas (LGAs) of Osun State. The analytical tools used include descriptive statistics and ordinary least squares (OLS) regression. The study revealed that urban households have higher levels of per capita food expenditure than their rural counterparts. In addition, household size and the income and educational level of the household head are significant determinants of food consumption among urban dwellers. On the other hand, in rural households, only the income of the household head was significant in determining food consumption.
