ABSTRACT This study attempted to assess socio-economic factors influencing adoption of improved technologies for maize farming in Karatu District. Specifically the study identified the types of maize production technologies used in Karatu District; analyzed socio-economic characteristics of maize farmers in Karatu District and identified socio-economic factors for adoption of maize production technologies in Karatu District. The study employed both probability and non-probability sampling m...
ABSTRACT The study was conducted to investigate the antibacterial activities of stem and leaves from Terminalia sericea and the live and dead bark from Combretum imberbe. The aqueous and organic crude extracts of the two plants were tested on Gram-negative bacteria Escherichia coli, Shigella sonnei, Serratia marcescens, Helicobacter pylori and Gram-positive bacteria Enterococcus faecalis, Staphylococcus aureus and Clostridium perfringens using the disk diffusion method. All the crude extracts...

Abstract: Production of biogas through anaerobic digestion of organic waste materials provides an alternative environmentally eco-friendly renewable energy. In this study, biogas production from co-digestion of the Justicia schimperiana and cow dung in five mix ratios,A100%JS, B 75%JS: 25%CD, C 50%JS:50%CD, D25%JS:75%CD, E100%CD was evaluated under mesophilic conditions (38ºC) using a batch digester in microbiology laboratory of Haramaya University. In all treatments, Total solid, Volatile ...
ABSTRACT Biomarkers or geochemical fossils are organic molecules that are present in petroleum and also in plants and animals. These biomarkers can be correlated back along the above pathway to identify source beds, correlate oil families and make interpretations about depositional environments andpost-depositional histories. To describe a sample chemically meansamassing the largest amount of data possible. The�...
ABSTRACT The study investigated the economics of catfish (Clarias gariepinus) production in Bayelsa State, Nigeria. The broad objective of the study was to examine the economics of Catfish production in Bayelsa State, Nigeria. The specific objectives were to: (i) describe the socioeconomic characteristics of catfish farming; (ii) determine the technical efficiency of catfish farming; (iii) identify factors that influence technical efficiency of catfish farming; (iv) analyze the costs and ret...

ABSTRACT Smallholder farmers play a vital role in food production in Ghana. However, their households are major casualties of food insecurity despite their efforts in food production. This study sought to identify the determinants of food security status and describe the coping strategies used among smallholder farming households in the Upper West Region of Ghana. The study calculated a food security index (FSI) to determine the food security status of households in the study area. The logit ...
Abstract/Overview The efficiency of rice husk biochar (RHB) and coconut shell biochar (CSB) in adsorbing Cadmium (Cd), as one of the prevalent heavy metals reported to bioaccumulate highly at the larval stage of the black soldier fly (BSF) was investigated. The synthesized biochars were activated using sulphuric acid and surface morphology investigated using SEM. The surfaces of CS biochar had well defined pores while RH had irregular pores of different sizes. Batch adsorption studies wer...
ABSTRACT Unsustainable forest land use practices have resulted in land degradation in the northern part of Nigeria leading to low crop yield. Agroforestry is a viable option for reversing dwindling crop yields through proper soil management practices. There is notably no sufficient published information on the contributions of agroforestry to food production in Katsina State. The practices of agroforestry and its potential to slow down the pace of soil degradation and boost food production in...
ABSTRACT The Lower Anayari catchment (LAC) located in the Upper East Region of Ghana, is part of the transboundary (Ghana and Burkina Faso) Anayari catchment. The other transboundary catchments are Atankwidi and Yarigatanga. These catchments are noted for intense farming activities. The population within Lower Anayari catchment area is estimated to be about 19,445. An estimate of about 80% of the population depends on groundwater for domestic and agricultural purposes. Agriculture has direct ...

ABSTRACT The study was carried out to determine the agricultural extension needs of farmers in Telfaria production and marketing in Enugu north agricultural zone of Enugu state, Nigeria. Four Local Government Areas (LGAs) namely: Udenu, Nsukka, Igbo-Etiti and Uzo-Uwani were used for the study out of the six Local Government Areas that make up both Nsukka and Enugu zones of Enugu north agricultural zone. In each of these Local Government Areas, two town communities were purposefully selected ...
ABSTRACT Untreated industrial effluents discharged into land and surface water are of great environmental concern. Previous studies on physicochemical characteristics of effluents and sediments from discharged points of various industrial sectors in Lagos metropolis are inadequate in scope, duration, chemical treatment options and estimated pollutant discharge load which are of importance in waste water management. This study was designed to investigate the physicochemical characteristics of...
