ABSTRACT
After receiving his agricultural diploma, Bertrand Lassaigne worked for several technical institutes and seed companies, evaluating and registering varieties, and assessing the effectiveness of several phytosanitary products. In the late 1980s, he decided to return to the land of his grandparents in Périgord and become a farmer. He attended a seminar on organic farming and resolved to adopt the practice of organic farming. He began selling his products locally, often directly to users who appreciated their local origin. Since most seed in the market is not organic, he also started to produce his own seed. Maize seed and varieties remained a problem because only hybrid varieties were available.
