It is my great privilege and pleasure to convey this massage to the proceeding of the 8th Annual Research Symposium 2016, Faculty of Agriculture, Rajarata University of Sri Lanka. The objective of the symposium is to endow with a platform for graduating students to present their undergraduate research and share the finding and latest information of the agricultural sector with their colleagues, industrial personals, scientists and academics from all over the Island. The constructive feedback that the research students may gather from the deliberations could pave the way to frontiers of research

This year, there are 66 abstracts from various disciplines, in the proceedings of the symposium. They are high quality research and would have, no doubt, cost each author a great deal in both time and energy; they are all highly appreciated for their efforts.

The role of the symposium is to coordinate the different events. This immense responsibility on me would have never been achieved without the talents, dedication and great support rendered by all the academics and nonacademics together with the students of Faculty of Agriculture. I would like to specially mention the proper guidance of Prof. Ranjith Wijayawardena, the Vice Chancellor, Rajarata University of Sri Lanka and the unflinching encouragement and motivation rendered by Dr. M.G.T.S.
