Microbiological and physicochemical analyses of top soils obtained from four municipal waste dumpsites in Benin City, Nigeria

Several methodologies were utilized to evaluate the microbiological and physico chemical properties of top soil samples bored from four municipal waste dumpsites and a farmland (control sample) all located in Benin City, Edo State. The soil samples were obtained during the month of January, 2013. The mean aerobic bacterial counts for the soil samples ranged […]

Evaluation of farm yard manure and some selected pre-emergence herbicides on the growth and yield of cotton in Samaru- Zaria, Nigeria

Field experiments were conducted in 2010 and 2011 cropping seasons to evaluate the effect of farm yard manure levels (0, 10, 20, and 30) tonnes per hectare and some selected pre-emergence herbicides (Alachlor, Metalachlor, Diuron and Oxadiazon) @ 1 kilogramme active ingredient per hectare on the growth and yield of cotton in Samaru, Zaria. Results […]

The effect of composition on the biodegradability and toxicity of drilling muds used at ologbo active onshore field, Edo State, Nigeria

The effect of composition on the biodegradability and toxicity of two muds commonly used at onshore oil fields at Ologbo, Edo State were examined. Biodegradation of drill muds by two bacterial and fungal isolates; Enterobacter aerogenes, Micrococcus sp., Aspergillus sp. and Penicillium sp. were carried in a shake flask experiment using mineral salts medium at […]

Physicochemical and enzymatic activities of mining effluent contaminated soil from Ishiagu Ebonyi State South- East Nigeria

Soil physicochemical parameters and enzymatic activities of mining effluent contaminated soil of Ishiagu, Ebonyi State Nigeria were evaluated. Effluents of Crush Rock, Crush Stone and Ezza quarry sites in Ishiagu were used for the study. Homogenized soil samples were collected at a distance of 100m (sample B), 200m (sample C) away from discharge points (sample […]

Nutritional and chemical composition of Jatropha curcas (L) seed oil from Nigeria

This study investigated the nutritional and chemical properties of Jatropha curcas (L) seed oil from Abia State, Nigeria using standard analytical methods. Proximate composition results show it is rich in protein (29.4%), carbohydrate (16.89%) and fat (46.89%). Low concentrations of phytonutrients were also detected; alkaloids (1.5g/100g), flavonoids (0.81g/100g). The seed is also rich in essential […]

Assessment of the levels of some heavy metals in mudfish (Clarias anguillaris) from River Okpokwu, Apa, Benue State, Nigeria

This study employed recommended analytical procedures to determine the levels of As, Mn, Cu, Pb and Fe in whole Clarias anguillaris (mudfish) obtained from river Okpokwu, Apa Local Government Area of Benue State, Nigeria. Samples of the fish, water and sediment were collected weekly at three commercial fishing locations: Auke, Odejo and Ocholonya in October, […]

Effect of plant population density and varietal differences on yield and yield components of onion (Allium cepa L.) in North Eastern Nigeria

Onion is grown extensively during dry season in the North eastern Nigeria for bulb as well as leaves production. The local producers were known to use random density planting in the field. This study is aimed to determine the optimum plant density for different local cultivars (Ex-Borno, Kano Red, Local Red and White). Trials were […]

Evaluation of tomato (Lycopersicon lycopersicum Mill.) for fruit yield and yield components in the southern Guinea Savanna ecology of Nigeria

Field experiments were conducted at the Teaching and Research Farm of the University of Agriculture, Makurdi during the 2010 and 2011 rain fed cropping season with the objective of evaluating the performance of tomato varieties in the Southern Guinea Savanna ecology of Nigeria. The experimental design was a randomised complete block design with three replications […]
