ABSTRACTPlant growth-promoting rhizobacteria (PGPR) are beneficial native soil bacteria that colonize plant roots and result in increased plant growth. Those that colonise the nodules of legumes are known as nodule associated bacteria (NAB). The aim of this study was to determine the distribution and genetic diversity of NAB that colonize Phaseolus vulgaris, their abundance, and symbiotic efficiency when coinoculated with Phaseolus vulgaris in Western Kenya soils. The soil samples were collec...
ABSTRACT Striga is an obligate root hemi-parasitic angiosperm that causes devastating cereal crop losses to millions of smallholder farmers in sub-Saharan Africa (SSA). The parasite causes the greatest effects on infertile soils thereby directly affecting the lives of the poorest subsistence farmers. The parasite attaches to a host crop‘s roots, and exploits its water and nutrients leading to stunted growth and death. Several cultural control methods including; crop rotation, use of t...
ABSTRACTPlantains are among staple foods in Africa. Worldwide, Musa spp. have an annual production of 88 million tonnes. Nematodes cause significant annual yield losses to these crops. The losses are estimated at about 20% worldwide. The most disastrous nematodes are Radopholus similis and Platylenchus goodeyi. Genetic improvement of the crops by conventional breeding has proved to be laborious and time consuming. Transgenic technology can offer sustainable solutions to the problem of control...
ABSTRACTRice, the second most important cereal crop globally, is mainly grown for food and is a staple food for more than half of the world’s population. In sub-Saharan Africa biotic stresses and lack of resources are major production constraints to food production. An estimated yield loss of 16% attributed to weed infestation is recorded in the region with Striga spp. being the most prominent. Striga hermonthica and Striga asiatica constrain production of cereals while Striga gesnerioides ...
AbstractSorghum is a subsistence and staple crop for many people living across Africa especially those in marginal arid and semi-arid tropics. While it is a staple food for millions of people in Africa, livestock feeding accounts for most of the sorghum used in the developed world especially in USA, Mexico, Australia, and South Africa. Among the major impediments to successful sorghum production is drought. This constraint is considered the most important cause of yield reduction in crop plan...
ABSTRACTInformation and communication Technology (ICT) plays a basic and key job in empowering associations meet their objectives and destinations. Despite the efforts to adopt ICT in the Kenya Revenue Authority (KRA) operations to enhance revenue collection, challenges still exist. KRA has failed to hit the set target on numerous occasions. The main objective of the current study was therefore to assess the effect of capability of information and communication technology on performance of Ke...
ABSTRACTDespite numerous health intervention measures available, severe dehydrating rotavirus diarrhea remains a major contributor towards childhood mortality particularly in developing countries. Global rotavirus surveillance is vital towards the development of safe, effective and efficacious vaccines to control the associated high infection rates. In Kenya, however, there is little corroborated data on rotavirus epidemiology, burden of disease and strains in circulation. The objective of th...
ABSTRACT This research work focused on the effects of Colocation arrangement on Cost Efficiency of selected GSM firms in Nigeria. The sources of data for this research work were exclusive primary data sources. Primary data sources for this research work were obtained from structured and standardized copies of questionnaire targeted to 200 respondents. The respondents are professionals or stakeholders in the area of the research interest. Data collected were subjected to multiple regress...
ABSTRACT This thesis examined some security related issues that might be unknown to computer users in Nigeria. It addressed the security vulnerabilities and flaws in most popular home computer operating systems. The study also concentrated on important computer security issues like worms, spyware, viruses etc. The researcher used the survey method for data collection via questionnaire method; therefore the data collection system in the research is primary data. The research reviewed pr...
ABSTRACT The study examined the role of freight forwarding in supply chain management in Nigeria, with particular reference to time and cost in cargo clearance. Freight forwarding has been portrayed by many authors and public as contributing little or nothing to the economy as a whole. It is based on this dysfunctional premise that the study investigated the time and cost of clearing by freight forwarder and self clearing option stipulated by the law. Freight Forwarders and Supply Ch...
ABSTRACT This study investigated the effect of produced water from an oil exploration company in Rivers State on the blood, gills and liver of Juvenile African Catfish (Clarias gariepinus). Seventy Juvenile African Catfish were separated into 7 groups (10 per treatment) and used for the study. The juveniles were exposed to three varying concentrations of fresh and stale produced water (2.5ml/l, 5.0ml/l and 10.0ml/l) for a period of 3weeks. At the end of the test period, haematological,...
ABSTRACT Almost all over Nigeria today, manual method of Hospital Record Keeping is the practice. No serious attempt has been made to join the Information Society by adopting new information technologies in a vital area like record keeping. This project, therefore, set out to investigate the drawbacks of manual methods on health service delivery, and subsequently designed an automated system to replace the manual method. Through participant observation and personal interview, data wer...
ABSTRACT Understanding road signs and pavement markings is an important aspect of the driving task. Consequently efforts have been made in this direction to optimize the use of traffic signs and markings by motorists but this has yielded little results. Therefore, the main objective of this study is to determine the level of understanding of traffic signs and markings by motorists. The primary data source was questionnaire administered and returned by motorists and road users. Secondar...
ABSTRACT Generally, failure in any system brings about production bottleneck, economic down-turn, hazards and other undesirable elements in Nigeria oil sector, especially oil refineries which are performing badly, leading to serious setback in the nation’s economy. This study, therefore, investigated the reasons for the failure. It also sought to understand the major areas in turnaround maintenance that could help in smooth running of the refineries. The study was executed through t...
ABSTRACT The Nigerian Maritime Administration and Safety Agency is a maritime regulatory agency and concerns with enormous responsibilities such as promoting indigenous shipping lines, shipping development, pollution control, ensuring adherence with IMO and ILO conventions among others, So based on the above functions, the research work will look into Information Technology as a sustainable index in the maritime industry. The research will first look into the development of information...
