In the retrospect of four months later, we can count the Conference as a great success. The theme – Research for Rural Development - attracted participation more than 150 researchers with very different backgrounds. There were 114 presentations from different universities of Lithuania, Netherland, Poland, Thailand, Kazakhstan, Iran, Nepal and Latvia. Thank you for your participation! I’m sure that you have learned from the presentations and discussions during the conference and you can use the outcomes in the future. The cross disciplinary proceedings of the Annual 19th International Scientific Conference “Research for Rural Development 2013” (2 volume since 2010) are intended for academics, students and professionals. The subjects covered by those issues are crop production, animal breeding, agricultural engineering, agrarian and regional economics, food sciences, veterinary medicine, forestry, wood processing, water management, environmental engineering, landscape architecture, information and communication technologies. The proceedings will be useful for researchers in educational sciences, too. The papers are grouped according to the sessions in which they have been presented. Finally, I wish to thank Organizing and Scientific Committee and the sponsors for their great support to the conference and proceedings.
