ABSTRACT
Soc Trang has the kirgest area of Tai Nguyen rice in the Mekong Delta "Milk Tai Nguyen "
grown in Soc Trang for a long time is a 6-monlh local rice variety characterized by pholoperiod smedl size and millq/color, sweet taste and soft cooked rice. Today, Tai Nguyen rice, however, is low qualily with while color, bigger ste. hard rice and wilhoul sweet taste.
As a result, most of users consume other nee instead of Tai Nguyen, either other soft-riee mixation or Soc Mien rice with the same Tai Nguyen shape and color thai have lead lo reduction of Tai Nguyen value in the recent years. Solutions for improvement cfTai Nguyen qualily and value-added are based on the ^'alue chain approach ofKaplinsfy & Morris (2001). the ValueLinks method of GTZ (2007). Marking value chains work better for the poor(M4P, 2008), rice lest and amylase analysis. Research results shosv that coruSlions for Tai Nguyen production create fugh compelilive and comparative advantages bel^^tven provinces; reduction of Tai Nguyen quality has happened in the entire chain; Tai Nguyen rice is mainly distributed to domestic market (93.1% cf total qutmlily) and limited volumfor export (6.9%), Less agents in a chain market channel higher benejils lo producers.
Furthermore, researchers also propose seven strategic solutions including 11 activities for improvement of Tai Ngi^n qiudity and value-added in the coming lime.
