The consumer awareness and interest in food quality is growing which leads to greater demand for organic products. Organic farming is helping to maintain biodiversity in the agro-ecosystems, as well as to preserve traditional species and varieties of crops and rare breeds of animals in certain regions or countries. The main objective of the paper is to observe the technical and economic efficiency of the three species of ancient wheat, grown under different technologies of organic fertilization and sowing rates. The study is conducted at the experimental centre for organic production at the Agricultural University – Plovdiv during the period 2014 – 2017. The analysis of results showed different levels of technical efficiency of the three wheat species, grown under different technologies of bio fertilizer treatment. On the other hand, the high prices of the approved fertilizers for organic production do not guarantee the economic efficiency of their application. In fact better economic results were observed without use of fertilizers. It was also concluded that higher sowing rates of the wheat species impacts positively on yields.
