This is a great opportunity to bring together producers, agronomist and researchers in the area of forage seed production from all over the world to share knowledge and experiences and to talk about common areas of interest. Herbage Seed production in Argentina has increased in the last years. Our exports have been going up while the imports have descended. At the same time, the demand for good quality forages has increased since cattle raising activities have been improving. This imposes and opportunity and a challenge for seed producers to improve their production systems and to us, researchers, to find new ways to help and contribute to this goal. We sincerely hope this conference will open the door to ideas and new areas of research and will give us, researchers and producers from South America, new insights to pursue further objectives to augment yield and quality of our seed production systems. I am very grateful to the local organizing committee for the hard work, responsibility and commitment in getting things ready for the conference. I am indebted to our sponsors for their support and contribution and to the organizing institutions for the possibility of putting together this conference. We deeply hope this conference will come up to your expectations and that you all have a productive conference and an enjoyable stay at our wonderful country. Yours sincerely, Maria Andrea Tomás President Local Organizing Committee of the 9th IHSG Conference 6 IHSG 2017 – Pergamino, Argentina Dear colleagues, We welcome delegates to the 9th IHSG Conference at Pergamino. This is the first time the Conference has been held in South America and is the culmination of four year’s work by Andrea Tomas and the local organizing committee. Our last conference was in 2015 at Lanzhou, China and these conferences were the first time that the IHSG had moved outside of Europe, North America and Australia/New Zealand. I have attended 7 of the previous 8 IHSG Conferences and a number of Workshops and I look forward to our time together in Pergamino. The value of Conferences is not only in the ideas presented in formal presentations both conference oral and posters, but in the informal sharing of ideas with other researchers, extension workers and seed growers. I encourage all delegates to make contact with two or more other international delegates that are working in areas that interest you. I have seed industry friends in Argentina that I first met at the 1st IHSG Conference in Denmark in 1987 and have kept in contact over the following year. I have been a regular visitor to Argentina and Uruguay over the past four years and have had the opportunity to visit many seed production farms/estancio’s. The post conference tour will give you a taste of seed and crop production in Argentina. Seed production in Argentina is both well established and with considerable scale. Higher spring/summer temperatures and shorter daylengths than the traditional herbage seed production areas of Oregon, Denmark and New Zealand that presents management challenges for seed growers. I know you will enjoy both the culture of South America and your interaction with seed researchers, seed company agronomists and extension advisors and seed growers who you will meet and interact with this week. Many thanks-muchas gracias to the Local Organizing Committee and sponsors who are helping to support the conference. Enjoy your week.
