ASSESSMENT OF FRUIT YIELD LOSS IN CUCUMBER DUE TO LEAF FEEDING BY Epilachna chrysomelina FABRICIUS (COLEOPTERA: COCCINELLIDAE)

Abstract Fruit yield loss in cucumber(Cucumis sativus L.) to leaf feedingby Epilachna chrysomelina Fabricius (Coleoptera: Coccinellidae) at six population densities (0, 1-,2-,3-,4- and 5-pairs per cage) was studied in screen house and field experiments. Increased beetle density, resulted into a significant reduction (P < 0.05) in the number of fruit, fruit length, fruit width and […]

IMPACT OF CEMENT DUST POLLUTION ON THE MORPHOLOGICAL ATTRIBUTES OF MAIZE (Zea mays L.)

Abstract Cement dust caused serious environmental pollution problem, the pollutants of the cement industry produced adverse impact on air, water and land. During the last decades, the emission of dust from cement factories has been increased alarmingly due to the expansion of more cement plants to meet the requirement of cement materials for construction of […]

INFLUENCE OF LEAF NUTRIENTS ON THE PHYSIOGNOMY OF Colophospermum mopane WOODLANDS

Abstract The study examined the extent to which plant nutrients can influence the physiognomy of Colophospermum mopane woodlands. C. mopane is an important ecosystem component and food source of the African elephant (Loxodonta loxodonta africana). C. mopane is dominant species in the two sites. Survey blocks were selected randomly inside monotypic C. mopane woodlands. In […]

EFFECT OF DIFFERENT FERTILIZER TYPES ON SOIL PHYSICAL PROPERTIES, GROWTH AND YIELD OF OKRA (Abelmoschus esculentus (L.) MOENCH (LD 88-1) IN SOUTHWEST NIGERIA

Abstract Residue quality is a huge determinant of how effective different fertilizers are on soil and crop plants. The aims of this study was to compare the effect of different fertilizer types on soil physical properties, growth and yield of okra {Abelmoschus esculentus (L.) Moench (LD 88-1)} in southwest Nigeria. Field experiments were conducted during […]

ASSESSMENT OF Dennentia tripetala Baker. F. SEEDLING GROWTH PERFORMANCE TO DIFFERENT WATERING FREQUENCIES

Abstract Water is an important factor in plant development. As important as water is, its excess can be dangerous and injurious to seedling; therefore the water requirement of seedlings at nursery level must be determined for effective performance of the plants. This study assessed the water requirement of Dennentia tripetala at nursery level. Sixty seedlings […]

ECOLOGICAL ASSESSMENT OF ITAPAJI RESERVOIR STATUS IN ITAPAJI USING PLANKTON ASSEMBLAGE

Abstract Itapaji Reservoir in Ekiti State serves for municipal water supply, artisanal fishing, agricultural and domestic uses, and recently earmarked for irrigation of the adjoining land.  There is paucity of information on the limnology of the reservoir, hence this study to provide relevant information on its trophic status for effective water management. Plankton samples (120) […]

ANTIOXIDANT AND ANTIMICROBIAL ACTIVITIES OF SOME NIGERIAN GREEN LEAFY VEGETABLES

Abstract This study evaluated the antioxidant and antimicrobial properties of Piper guineense, Ocimum gratissimum, Murraya koenigii and Gongronema latifolium leave extracts using ethanol, petroleum-ether and aqueous media. The scavenging activities of the extracts was measured with free radical 2, 2-diphenyl-1-picrylhydrazyl, flavonoid and phenolic contents were assessed by spectrophotometry while, gas chromatographic flame ionization detector was […]

PLANT DIVERSITY ON MOUNTAIN SITE; A CASE STUDY OF IDANRE HILL, ONDO STATE, NIGERIA

Abstract An investigation of the plant diversity of Idanre Hill was carried out using quadrant sampling technique and an extensive assessment of plant species found along different gradients namely, mountain top, midpoint and foothill. Quadrat size of 10m2 was randomly placed in 10 points on each elevation, followed by qualitative and quantitative vegetation description. Life […]
