Foreword: The International e-Conference on Agricultural Biosciences (IeCAB) continues to provide a platform for scientists in developing countries to exhibit and publish their research outputs in an easy, facilitated and cost-effective manner. This is the 4th e-Conference since the launch of this initiative in 2008.  As in the previous years scientists have an opportunity to present their papers as power point slides or posters and eventually to publish the outputs as full papers in peer reviewed journals. All materials submitted to the e-Conference are archived online permanently. This ensures sustained visibility and presence on the web, with free access and download. We encourage scientists to utilise this innovative platform as they endeavour to take their careers to the next level.   The coordinators appreciate those who have submitted abstracts included in this volume. We welcome you to join us in the 5th e-Conference in mid-2012. You may also submit your papers for direct publications in the online Journal of Applied Biosciences ISSN 1997-5902; Journal of Animal and Plant Sciences ISSN 2071-7024 and Biosciences Research Images Journal, all accessible at www.m.elewa.org/journals.

Links to all outputs of this e-conference can be accessed at http://www.m.elewa.org/econferenceIeCAB.php. We welcome you to this e-conference and trust you will find something of value in your area of interest. Please let us know how we can make this initiative better.
