ABSTRACT Cowpea, Vigna unguiculata, is an important human and livestock protein source in Nigeria, but its production is constrained by ravages of pests and climate change. Conventional breeding efforts used to fortify it against these constraints had resulted into its narrow genetic base. In order to overcome this challenge, other mutation procedures such as physical and chemical mutagens could be used. Nevertheless, information on gamma and ultra-violet (UV) irradiated cowpea seeds and pol...
ABSTRACT The influences of water pre-treatment temperature and cement/wood mixing ratios on static and moisture response properties of cement-bonded particleboards produced from mixed Nigerian hardwood species were assessed in this study. The process variables for board fabrication were pre-treatment temperature (5 levels) and wood/ cement mixing ratios (5 levels) resulting in 25 treatment combinations in a factorial experiment. The examined properties are modulus of rupture (MaR), modulus of...
ABSTRACT Logging induced damages associated with two different ,harvesting systerns (Conventional Timber Harvesting and Reduced-Impact Logging (RIL» were investigated in 19.84 compartment of Gmelina arborea plantation in Omo Forest Reserve. The same equipment and felling crew were used for both methods. Felling was done using heavy chainsaw (Stihl 070) and skidding was carried out with crawler tractor. The types and severity of damage to the residual stand were determined for felling and sk...
Abstract Vegetables are grown for human consumption all over the world. Indigenous Leafy Vegetables (ILV), both wild and domesticated species make important contributions to household improvement in Nigeria. However, information on availability of these species in the market and the consumption level at household is limited. Therefore, ILV species in southeastern Nigeria were investigated in order to determine their availability and consumption level. Multi-stage random sampling procedure w...
Abstract The trend of news frame in the print media has implications for public perception of emerging development issues and actions that members of the public in general and farmers in particular will take in similar situations in the future. Combining the occurrence of climate change topical news variables and framing theories, this study content-analysed 111 climate news items framed in three Nigerian newspapers (the Guardian, Punch and Nigerian Tribune) between January 2010 and June 201...
ABSTRACT The objective of establishing protected areas should be made to tally with needs and aspirations of the local community. Interaction between the local populace and the ecosystem plays a significant role in the determination of effective management. Overgrazing by cattle and deforestation by human activities over time has denuded the Obudu Cattle Ranch, Cross River State, Nigeria, of its lush natural flora. Consequently, its productivity as grassland has drastically been reduced. Den...
ABSTRACT Toxicity testing of chemicals on animals has been used for a long time to detect the potential hazards posed by chemicals to man. Bioassay technique has been the cornerstone of programmes on environmental health and chemical safety (Ward and Parrish, 1982). Lead is a potentially toxic chemical that may be directly ingested by man or indirectly through aquatic animals like fish and shellfish .The effects of lead on man include mental retardation, learning dysfuntion, and loss of coord...
ABSTRACT The deficit of domestic fish supply necessitates importation of frozen fish to supplement protein intake of Nigerians. Adequate quality standards and control measures are in place for frozen fish at the point of entry to the country. However, there is dearth of information on quality control along the distribution chain to the final consumer. Therefore, quality and handling procedures of imported frozen fish within Oyo State were investigated. Three-stage sampling procedures were us...
ABSTRACT The quality of Amaranthus cruentus L. seeds were influenced both by seasons of harvest and varietal type. The wetness that accompanied harvests of the first (April June) and second (August-October) seasons greatly-reduced the quality of seeds of cultivars. Quality reduction were in the form of seed malformation, discolouratlon and mycelial growth on them. Fifteen fungal species were found to be associated with seeds of the cultivars used. There was a seasonal variability in the occu...

ABSTRACT Implementing sustainable development and meeting the food needs of world's increasing population demand national and international investment in research and extension. Before fruitful investment can be guaranteed, inventoly of the present status of the object of investment is imperative. This study examined the present status of public extension network in southwestern Nigeria with a view to ascertain its readiness as a learning organization for forest conservation information. Purp...
ABSTRACT Clash of interests between custodians of government Forest Reserves (FRs) in Ogun State and farmers operating within them, often results in conflicts causing disruption of socio-economic activities and sometimes loss of lives. Information on the causes and effects of these clashes would better inform policy makers and forestry professionals on workable and sustainable land-use practice. Therefore, factors responsible for such conflicts and their effects were investigated. Seven hund...
ABSTRACT Weed infestation of soyabean field causes 65% yield reduction in the forestsavanna transition ecosystem of Nigeria. Single weed control method is often less effective. However, Integrated Weed Management (IWM), will ensure more effective and environment friendly control. There is little information on IWM application on soyabean field. This study was therefore aimed at investigating response of soyabean to IWM. Field study was carried out in the 2008 and 2009 planting seasons to as...
ABSTRACT High cost of conventional feedstuffs and competition between livestock and fish for ingredients necessitate research into low cost, non-conventional feedstuffs for profitable fish farming. In aquaculture, the emphasis is on producing feeds that promote growth and health of fish. There is scanty documentation of the potential of onion (Allium cepa) bulbs and walnut (Tetracarpidium conophorum) leaves in fish production. The growth performance of Clarias gariepinus on diets containing ...
ABSTRACT Tomato yellow leaf curl viral disease (TYLCV) is a destructive disease of tomato in Ghana. The study was conducted during the 2013 minor and 2014 major cropping seasons to determine the knowledge of farmers and their agronomic practices they carry out to manage TYLCV disease in three districts in the Central region, screening of thirty six tomato genotypes against TYLCV disease for a possible tolerant variety and phenotypic and molecular evaluation of selected tolerant genotypes at ...
