ABSTRACT Integrated Nutrient Management with biochar and inorganic fertilizer is critical to sustainable agriculture including the enhancement of production systems for climate change mitigation and adaptation. The objective of this research was to evaluate how soil management could be improved to respond to increasing environmental pressure on soil and crop in carrot production and to examine how anthropogenic changes in and management of soil affect crop growth, yield and nutritional...
ABSTRACT This study identified the types of soil ameliorant that exist in the Greater Accra Region of Ghana. It also determined farmer's willingness to pay for composted urban waste as well as the amounts they were willing to pay for a 50kg bag of compost should it result in a 25% and 50% increments in output, respectively. The study further investigated the socio-economic factors that affect farmer's willingness to pay for compost. The results obtained further revealed that different types o...
ABSTRACT The experiments were conducted at the Department of Crop Science Analytical Laboratory and green house of Faculty of Agriculture, University of Nigeria, Nsukka. Experiment one was an analysis of the nutrient contents of fermented and unfermented plant waste materials using the official method of analysis of Association of Official Analytical Chemists (AOAC). Experiment two was on assessment of the effects of plant wastes and different forms of organic manure fermented for one or two...

ABSTRACT Fungal diseases are prevalent in fish and have the potential of limiting productivity in aquaculture. This study aimed to isolate and determine fungal infections in hatchery with female Rufiji tilapia and their hybrids of male Rufiji tilapia and female Nile tilapia. An experimental study design was conducted to determine the occurrence of fungal infections and to characterize the isolates of Aspergillus flavus and Aspergillus niger. Fish samples were randomly collected from the hatch...
Abstract An experiment was conducted at the Teaching and Research farm of the Department of Crop Science, Faculty of Agriculture, University of Nigeria, Nsukka in the 2006 cropping season, to assess the effects of planting distance and organic manure rates on yield and nutrient composition of waterleaf at Nsukka. in Southeastern Nigeria. Treatments comprised five planting spacings and four manure rates. The planting spacings were 25cm x 10cm, 25cm x 15cm, 25cm x 20cm, 25cm x 25cm and 25cm...

Abstract: Biogas is an alternative and renewable energy source produced through anaerobic digestion of organic matter whereby the organic matter is converted into a combustible gas rich in methane (CH4),solid residue(sludge) and a liquid effluent. The aim of this study was production of biogas from Argemone ochroleuca co-digested with cow manure under mesophilic conditions (38ºC) using batch digester for 30 days of fermentation time. The experimental design was completely random design with...
Abstract: Biogas is an alternative eco-friendly renewable energy source that produced by methanogenic bacteria through anaerobic digestion of organic materials. In this research, biogas production from co-digestion of the cow dung (CD) and groundnut shell (GS) with five mix ratios (T1 100%CD,T2 75%CD+25%GS,T3 50%CD+50%GS,T4 25%CD +75%GS,T5 100%GS) was evaluated under mesophilic conditions (38ºC) using batch fermentation for 21 days. The substrates were prepared with different total solid pe...
ABSTRACT The radiological impact of naturally occurring radioactive materials (NORMs) from the usage of phosphate and organic fertilizers in the New Juaben Municipality of Ghana was investigated. The activity concentrations of 226Ra, 232Th and 40K were measured in seven (7) widely used phosphate and organic fertilizers using gamma spectroscopy. The activity concentrations were found to be 32.10±2.60 Bq/kg, 12.20±1.60 Bq/kg and 3005.50±68.80 Bq/kg respectively. The radioactivity level index...
ABSTRACT This thesis presents the study in the assessing the contribution of environmental monitoring policies in the fight against global warming in Tanzania. The effect of global warming that leads into climate change are of concern both for environment and human life. Evidence observed in climate change includes the instrumental temperature record, rising of the sea levels, and deceased snow cover in the Northern Hemisphere. To reduce the risk of large changes in future climate, many count...
