Effects of some physical and chemical characteristics of soil on productivity and yield of cowpea (Vigna unguiculata L. Walp.) in coastal region (Cameroon)

  Studies were conducted to assess the response of cowpea (Vigna unguiculata L. Walp) to some physical and chemical characteristics of soil in coastal region (Cameroon). The cowpea variety used in this trial was Tsacre, planted at a spacing of 80 cm × 80 cm. The experimental design was a randomized complete block comprising of five plots with three replicates. Productivity parameters (dry weight...

Prevalence of soil transmitted helminths and impact of Albendazole on parasitic indices in Kotto Barombi and Marumba II villages (South-West Cameroon)

  This study assessed the actual prevalence of geohelminths and the impact of albendazole on parasitic indices in Kotto Barombi and Marumba II. Stools samples were collected from 420 school children and examined using the Kato-katz faecal technique. Participants were treated with 600 mg of albendazole. Baseline prevalence of infections and mean parasite loads were 26.4% and 6226.9e/g (Ascaris lumbricoides),...

Ground magnetic study of Ilesa east, Southwestern Nigeria

  Ground magnetic survey of eastern part of Ilesa town in Osun State, Southwest Nigeria was performed. Total field magnetic data was recorded using high resolution proton precision geometric magnetometer which implores total components of the ground magnetic anomaly data running through fifteen traverses. This research focused on delineation of faults in this part of the highly mineralized Ilesa schist belt....

Influence of mine drainage on water quality along River Nyaba in Enugu South-Eastern Nigeria

  Major and trace elements concentration were measured in water samples collected in and around Okpara coal mine in Enugu southeastern Nigeria to investigate the influence of mine drainage on the quality of water. The cations and trace elements were determined by ICP- MS while the anions were measured by spectrophotometer and titration methods. Field parameters such as pH, temperature and conductivity were...

Determination of physico-chemical parameters and heavy metals in water samples from Itaogbolu area of Ondo-State, Nigeria

  Water samples from selected hand-dug wells and Ona River in Itaogbolu area of Akure, Ondo State, Nigeria were collected, physico-chemical parameters and heavy metals were determined using standard analytical procedure. The results of the physico-chemical analysis were obtained in the  following range; PH (6.59-7.68), temperature (21.10-27.10ºC), conductivity (300-1150 µÎ©/cm), chloride...

Stabilization/solidification of synthetic Nigerian drill cuttings

    In the Nigerian oil and gas industry, large quantities of oily and synthetic drill cuttings are produced annually. These drill cuttings are heterogeneous wastes which comprises of hydrocarbons, heavy metals and chlorides. Currently, the treatment option for these drill cuttings is thermal treatment, which does not remove these toxic contaminants. In this study, the use of...

Weed management in banana production: The use of Nelsonia canescens (Lam.) Spreng as a non-leguminous cover crop

  During a survey of weeds in the Tiko banana plantations, the plant Nelsonia canescens(Lam.) Spreng was found to have invaded large areas of the plantation with no visible adverse effects on the banana crop. The effects of this Acanthaceae on banana yield parameters, snails’ population and weed species diversity and abundance were evaluated, with the intension of recommending the plant as a cover...
