Abstract Planting espacement is a vital process which affects the quality of tree’s growth and development but this information is lacking in Monodora tenufolia (a multipurpose species). This study aimed at obtaining the appropriate espacement for plantation of this species by subjecting seedlings to three (3) different espacement on field trial. Forty five (45) seedlings […]
ASSESSMENT OF CLOVES, Eugenia aromatic (Baill.) AS AN ENTOMOCIDE AGAINST THE BEAN BRUCHID BEETLE, Callosobrucus maculatus (Fabricius) AND THE MAIZE WEEVIL, Sitophilus zeamais (Motschulsky)
Abstract The potency of the medicinal plant, Eugenia aromatica as a biocide against storage insect pests of cowpea and maize was assessed in the laboratory. Different treatment doses 0.0g (Control), 0.5g, 1.0g, 1.5g and 2.0g of E. aromatica were applied on maize seeds infested with Sitophilus zeamais and cowpea seeds infested with Callosobruchus maculatus. The […]
THE EFFECT OF TEMPERATURE AND PHOTOPERIOD ON BIOREMEDIATION POTENTIALS OF MONO AND MIXED CULTURES OF CHLOROPHYTES AND CYANOBACTERIA FOR MUNICIPAL WASTEWATER TREATMENT
Abstract Investigation on organic xenobiotics bioaccumulation/biodegradation in green algae is of great importance from environmental point of view because widespread distribution of these compounds in agricultural areas has become one of the major problems in aquatic ecosystem. Temperature, light intensity, amount and type of nutrients, amount of CO2, and pH are the key factors influencing […]
APPLICATION OF PRE-EMERGENCE HERBICIDE PLUS MANUAL WEEDING ON CONTROL OF WEED, GROWTH AND YIELD OF TURMERIC (Curcuma longa L) AT AFAKA KADUNA, NIGERIA
Abstract A field experiment was carried out at Department of Crop production Experimental Farm, Federal College of Forestry, Afaka, and Kaduna, Nigeria to investigate the application of pre-emergence herbicide followed by manual weeding as an integrated weed management control system on growth and yield of turmeric. The experiment was carried out between 2019 and 2020 […]
THE POTENTIAL OF INDIGENOUS PHYTOPLANKTON IN PHYCOREMEDIATION OF EFFLUENTS IN RIVER GINZO KATSINA METROPOLIS, KATSINA STATE, NIGERIA, UTILIZING THE MESOCOSM TECHNIQUE
Abstract Sewage disposal has become a major ecological problem in metropolitan areas and semi-urban communities, with effluents from both residential and industrial activities discharged directly into water bodies, constituting a major cause of water pollution. Twelve mesocosms were set up, each receiving approximately 15 liters of water containing algae. Weekly sampling for physical chemical parameters, […]
FLORISTIC STUDIES ON TREES AND SHRUBS GROWING IN UMARU MUSA YAR’ADUA UNIVERSITY, KATSINA, NIGERIA
Abstract This study assessed the composition, distribution and diversity of the trees and shrubs growing in Umaru Musa Yar`adua University, Katsina State. Five sites were established during a pilot survey and identified as A, B, C, D and E and five plots of 30m×30m were mapped out in each of the five sites. All the […]
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 […]
