Average seed yield in the Czech Republic is 0.6 t ha-1 and 6-7 t ha-1 stem. This study focuses on summarizing information about the cultivation, fertilization and the possibilities of using hemp.The first part is devoted to the origin, botanical characteristics, morphology and anatomy and principles of cultivation. The second part deals with the chemical composition, effective substances and use of cannabis in various industries. In this work was proposed five years crop rotation period for a variety Bialobrzeskie, grown for seed and stem. Than were selected pre-crops suitable for business without animal production and determined doses of nitrogen, phosphorous, potassium and magnesium fertilizers and suitable harvest mechanization
