On 12 November 2008, Gratuate students in Gyeongsang National University, South Korea defened their thesis. And there had five Msc. students in agonomy department who presented their resarch including me. In that day, I presented my research on "Evaluation Studies on Applicability and Strategies for Improvement of SRI (The Systems of Rice Intensification) with Direct Seeding Chinese milk vetch residue-mulched No-till Paddy Rice (Oriza sativa L) in Southern Korea."
The objectives of this research were to investigate soil nutrients, weed occurrences, early growth and development, grain yield and yield components.
System of Rice Intensification was introduced to Cambodia by CEDAC who learned about SRI from the Low External Input for Sustainable Agriculture newsletter (LEISA) in December 1999 (Rabenandrasana 1999). In 2000, CEDAC also received more information on SRI from CIIFAD (Uphoff 1999 and 2000). In the year 2000, there were only 28 cooperating farmers adapted SRI. In the year 2005, there were about 40,000 farmers adopted SRI in 20 provinces.
