Rice has been closely familiar with Vietnamese people and villages for thousands of years. Rice is the primary food source of the people; it ensures food security, and rice cultivation has become a beauty in the cultural and spiritual life of Vietnamese people. Today, the development of science and technology has achieved many achievements in the rice production industry, but it also affects the production of traditional indigenous rice varieties. Therefore,learning traditional knowledge to preserve and develop indigenous rice genetic resources is extremely necessary in the current period. Teo Meo is an indigenous rice variety of the H'Mong people in Phong Tho district, Lai Chau province. The results of the traditional knowledge investigation play an essential role in preserving and using Te Meo rice genetic resources to serve food security and local economic development. Traditional farming techniques for the Te Meo rice variety of the H'Mong people, such as cultivating one crop per year, not using pesticides, and not inorganic fertilizers, etc., are good, sustainable, and eco-friendly farming methods, suitable for producers, and safe for users, those need conserved, maintained, and developed in agricultural production. However, other traditional farming techniques must be improved, such as selecting varieties, using reasonable fertilizers, and controlling pests and diseases to achieve high economic efficiency. The H'Mong community needs support in science and technology to choose and restore the Te Meo variety. In addition, research is required to improve several farming techniques (density, fertilizer level, harvest time, storage, etc.) to cultivate Te Meo rice to achieve high productivity and quality and achieve high economic efficiency. This issue requires technical support from scientists for sustainable rice cultivation associated with the in-situ conservation of Te Meo rice genetic resources in the Bac Dao San area, Phong Tho district, Lai Chau province.
