VALUATION OF THE CONSUMPTIVE AND PRODUCTIVE USES OF WILD AND DOMESTICATED INDIGENOUS LEAFY VEGETABLES IN SOUTHEASTERN NIGERIA

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 was ado...

SILVICULTURAL AND CONSERVATION TECHNIQUES FOR Khaya grandifoliola C. DC. IN SOUTHERN NIGERIA

Khaya grandifoliola, an important economic hardwood species, has been severely depleted by overexploitation. This necessitates its ex-situ conservation and requires in-depth knowledge of nursery handlings, seed storage, in-vitro and ex-vitro propagation on which information is sparse. Therefore, silvicultural requirements for conservation and sustainable use of K. grandifoliola in some parts of southern Nigeria were investigated in this study. Seeds of K. grandifoliola were purposively s...

CONTRIBUTIONS OF SELECTED NON-TIMBER FOREST PRODUCTS TO COMMUNITY LIVELIHOODS IN TARABA STATE, NIGERIA

Non-Timber Forest Products (NTFPs) have been identified to contribute to community livelihoods. Such contributions are people as well as site specific and may be short lived if continuous availability cannot be guaranteed. Information on the role of NTFPs in community livelihoods is crucial to their sustainable management; however, this role has not been properly documented in Taraba State. Therefore, contributions of selected NTFPs to community livelihoods in Taraba State were investiga...

CHARACTERISATION OF SELECTED WOOD PROPERTIES OF THERMALMODIFIED Bambusa vulgaris SCHRAD.EX J.C.WENDL

The preservative treatment of non-durable lignocellulosic materials, such as Bambusa vulgaris (bamboo) enhances its service life. Thermally modified lignocellulosic biomaterial is better than chemically treated products because it is environmentally friendly. However, there is a dearth of information on the characterisation properties of thermally modified Bambusa vulgaris. This study was therefore conducted to characterise the properties of thermally modified Bambusa vulgaris. One thou...

MODELS FOR GROWTH CHARACTERISTICS AND THEIR APPLICATIONS IN YIELD STUDIES FOR Pinus caribaea Morelet 1851 IN SOUTHWESTERN NIGERIA

Development of empirical models provides ample prospects of exploring established mathematical theories and relationships among tree growth variables for sustainable forest management options. However, there is inadequate information on modelling growth characteristics and productivity potentials of Pinus caribaea, a pulpwood species which is now being proposed for timber production in Nigeria. Hence, models for growth characteristics and their applications in yield studies for Pinus car...

Hydrogeochemistry And Isotopic Study Of The Origin Of Underground Mine Water At Golden Star Bogoso/Prestea Limited (New Century Mines

ABSTRACT Hydrogeochemical study of the origin of underground mine water at Golden Star Bogoso/ Prestea Limited (New Century Mines) was carried out to determine the geochemical processes controlling surface water, groundwater and underground mine water and to identify the source of recharge to the underground water in the mines; investigate the hydrochemical facies of groundwater in the various aquifers (gallaries), and identify the relationship between surface water and groundwater, and under...

Analysis Of Institutional Solid Waste Management Practices: Insights From Two Ghanaian Universities.

ABSTRACT Academic institutions produce solid wastes which are not disposed off effectively or economically. The result is littering and accumulation of garbage which cause pollution. This study examined solid waste generation and management practices in public and private institutions. To achieve the above objective, waste audit was carried out over a period of three weeks. Waste management practices of the institutions were also examined through the assessment of the institutional arrangemen...

Efficacy Of Locally Produced Papain Enzyme For The Production Of Protein Bait For Bactrocera Invadens (Diptera: Tephritidae) Control In Ghana

ABSTRACT Autolysed brewery yeast waste is currently being used as cost effective protein bait for Bactrocera invadens control the world over to replace commercial protein hydrolysate bait formulations. However, significant reduction in production cost can be achieved when all the production materials are from local sources. This experiment was aimed at assessing the efficacy of locally produced papain extracted from ―Red lady‖ pawpaw fruit latex and skin peel to be used for protein bait p...

User Satisfaction With Architectural Designs of Spaces in Residential Buildings; Insights on Low Cost Housing in Plateau State, Nigeria

ABSTRACT User satisfaction with residential houses generally is tied to many variables, but this research aims at examining user satisfaction with architectural designed spaces of residential buildings using insights from Plateau State Low-cost housing. The designed spaces of low-cost houses constitute verandah, living room, dining, kitchen, store, bedroom, toilet/ bathroom courtyard and external spaces for parking and outdoor activities. Physical observation of low-cost houses in Plateau St...

Access To And Management Of Credit By Rice Farmers At The Kpong Irrigation Project.

ABSTRACT The study was conducted in the Dangbe West District of the Greater Accra Region. The main objective of the study was to find out how rice farmers access and manage credit to improve their families standard of living. The specific objectives were to find out about available credit packages for rice farmers at the Kpong Irrigation Project, examine why rice farmers at Kpong Irrigation Project access credit, determine the benefits rice farmers may derive from using credit, evaluate the p...

Thz Potential 07 Using Hydrothermal Treatment For Protection Of Stored Cowpeas.Against Callosobruchus Maculatus (F.)

ABSTRACT Laboratory experiments were carried out to evaluate the effect of steaming cowpeas on the oviposition and larval development of the cowpea beetle, Callosobruchus maculatus (F.). The possibility of oven and solar drying as well as the effect of the initial temperature of the cowpeas on the steaming effect were also investigated. Samples of four cowpea varieties (Soronko, Asontem, Amantin and US Blackeye) were steamed for 10 and 15 minutes and solar or oven dried. Some initially stored...

Impacts of Solid Wastes Usage as an Alternative to Fertilizer on Maize Production in Pyasaka District, Abuja

ABSTRACT This study was conducted with the aim of experimenting the soil nutrient status and yield content of maize grain harvested from farmland enriched with solid waste, mmeral fertilizer (NPK) and control site respectively, in Pyakasa District, FCT, Abuja. Three randomized blocks of 50m2 in size, with three treatments and three repetitions, each was conducted. N- P- K fertilizer rates: 44- 15- 17 .5 (standard fertilizer recommendation for maize) was applied at block 'A,' while block B wa...

Impact of Slums on Value of Residential Properties in Jahi District of FCT, Abuja
