warmly extend my heartiest gratitude for the 11th Annual Research Symposium 2019 of the Faculty of Agriculture, Rajarata University of Sri Lanka. Research is the link among Universities, Industries and Research Institutes. The collaboration among them is mutually beneficial for both parties leading to sustainability of collaborative programs. It also has a clear potential to make a significant contribution to the quality of higher education. Therefore, this symposium would provide a platform to present and publish research work carried out by final year undergraduates under the guidance of academic staff and the outside subject experts. Most of the researches conducted are applied research that address most of the issues directly related to the agriculture development of the country. It is evident that the quality of the research and symposium proceedings have reached a commendable level showing the commitment of the academic staff and the students to develop the research culture in the Faculty. I would also like to extend my sincere gratitude to Dr. A. M. J. B. Adikari, Dean of the Faculty of Agriculture, Dr. (Mrs.) D.M.S.H. Dissanayaka, Coordinator of the symposium, Dr. (Mrs.) S. N. Dissanayake, the Editor-in-chief of the proceedings of the 11th Annual Research Symposium 2019, all academics and non-academics of the Faculty of Agriculture for the immense support, commitment and cooperation for making this event successful. Finally, I extend best wishes for those who present their research findings at the 11th Annual Research Symposium, 2019.
