This study assesses the tree species with medicinal properties within Sudano-Sahelian region of Nigeria. The data was collected through field survey of the tree species; structured surveys questionnaires which were administered randomly to the traditional herbal healers within […]

UTILIZATION OF MEDICINAL PLANTS AS INFLUENCED BY SOCIO-ECONOMIC STATUS OF RURAL DWELLERS IN SELECTED LOCAL GOVERNMENTS IN IBADAN

Abstract The study was designed to investigate the utilization of medicinal plants as influenced by the socio – economic status of the rural dwellers in Onipe and Laaniba villages at Oluyole and Akinyele Local Government Areas in Ibadan, Oyo State, Nigeria. Many medicinal plants today either face extinction or loss of genetic diversity; hence, posing […]

INFLUENCE OF SITE VARIATION ON Jatropha curcas SEED YIELD AND QUALITY OF BIODIESEL

Abstract Influence of site variation on Jatropha curcas seed yield and quality of biodiesel from three seed sources (Ibadan, New Bussa, and Kano) was investigated. Biodiesel was produced using oil extracted from the three seed sources using standard laboratory methods. Completely randomized design at three replicates per treatment was adopted for the experiment. The biodiesel […]

MELISSOPALYNOLOGICAL ANALYSIS OF HONEY TO DETECT MELLIFEROUS PLANT SPECIES VISITED BY Apismellifera adansonii latereille (West African Honeybee) IN GUINEA SAVANNA ZONE OF NIGERIA

Abstract Honey collection is a long aged traditional activity throughout most parts of Africa. Melissopalynological analysis is widely used to verify geobotanical origin of honeys. Although continuous destruction of forest and different vegetation as a result of incessant demand for land is affecting the population of honey bee, pollination, honey yield, and loss of gene […]

GROWTH POTENTIALS OF Tectona grandis LINN AS INFLUENCED BY SEED SOURCES AND DIFFERENT SOIL TYPES

Abstract The forest has been very useful to man as he obtains food, shelter, revenue, energy and myriad of environmental services from it. However, increase in demand for forest product as a result of overpopulation couple with urbanization has resulted in over exploitation and extinction of some forest trees. Therefore, there is an urgent need […]

NUTRIENT CYCLING THROUGH PRECIPITATION PATHWAYS: RAINFALL, STEMFLOW AND THROUGHFALL IN Diospyros crassiflora (Hiern) PLANTATION IN UMUAHIA, ABIA STATE- NIGERIA

Abstract The study of nutrient cycling through precipitation pathways in Diospyros crassiflora plantation was conducted in the Humid Forest Research Station, Forestry Research Institute of Nigeria between 2016 and 2017.The experiment was 3 x 9 x 2 split- split plot design in a Randomized Complete Block Design with three replications. Treatments were precipitation pathways (rainfall, […]

In Vitro REGENERATION OF Eucalyptus camaldulensis DEHNH. PLANTLETS FROM MICRO-CUTTINGS

Abstract Clonal propagation of Eucalyptus camaldulensis through stem cuttings is limited by a range of problems such as low root frequency, loss of rooting competence and poor rooting quality which can be overcome through plant tissue culture. Hence, efficient method of plantlets regeneration was developed for the species with a view to enhance its propagation. […]

INFLUENCE OF WATERING REGIMES AND BAMBOO BIOCHAR ON THE GROWTH AND BIOMASS PARTITIONING OF Neolamarckia cadamba (roxb.) miq. SEEDLINGS ON AN ALFISOL

Abstract The choice of Neolamarckia cadamba for reforestation and agroforestry programs in Nigeria could be constrained with lack of basic knowledge on the species-management in relation to its sensitivity to water and growth on low fertile soil. Hence, growth of the species as influence by watering regimes and bamboo biochar was evaluated. Treatments involved three […]
