GEOSPATIAL ECOLOGICAL DISTRIBUTION OF CRYPTOGAMIC FLORA IN SWAMP FOREST RIPARIAN VEGETATION IN PARTS OF RIVERS STATE, NIGERIA

Abstract Cryptogamic pteridophytes are primitive group of ferns sensitive to environmental disturbance; they serve as indicators and monitoring agent to the environment. This study was aimed at assessing their distribution using GIS techniques in parts of swamp vegetation of Forestry Research Institute of Nigeria (FRIN); with the objective of establishing the spatial distribution of the […]

SURVIVAL RATE OF ROOT PRUNED WILDLINGS AND COPPICE SHOOTS GROWTH IN STUMPED Garcinia kola (Heckel) SAPLINGS IN RIVERS STATE, NIGERIA

Abstract Study of survival rate of root pruned wildlings and coppice shoots growth in Garcinia(G.) kola was conducted in FRIN. G. kola wildings were collected under 28-year-old plantation, and classified into six treatments, namely: two leaves (T1), four leaves (T2), six leaves (T3) eight leaves (T4), wildlings with branch (T5) and untreated wildlings (control) (T6.  […]

VASCULAR DIFFERENTIATION AND SIMILARITIES OF Anthocleista species COMMONLY FOUND IN PARTS OF SOUTHERN ECOLOGICAL ZONE OF NIGERIA

Abstract Vascular differentiation and similarities is a function of anatomical diagnosis of plant species. Various lines of taxonomic evidence have been drawn on the four Anthocleista species recorded in southern Nigeria; however, not much effort toward the anatomy of the four taxa has been made. Thus, the aim of this study was to determine the […]

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 […]
