Investigations were carried out on the territory of the Chuvash Republic. The following hashish-free monoecious hemp varieties were used as the object of investigation: Diana, Rigs, Ingreda, Margo, Diman, Yuliana, Antonio, Igorkin, which are characterized by high uniformity of monoecious, absence of cannab. The experiments laid in 2005-2013, respectively. To conduct field and laboratory investigations seed crops placed on spatially isolated gray forest medium loamy soils, which are contained in the plow layer: humus - 4.69%; P2O5 - 100, K2O - 260 mg per kilogram of soil; pH - 5.9. The observations and analyzes were performed in accordance with the guidelines of bast crops of Russian Research Institute of Flow. The studies have shown that such chemical elements dominate in the hemp seeds: calcium, magnesium, phosphorus, potassium, sulfur, and a small amount of iron and zinc; rare earth elements - thorium, selenium, molybdenum, zirconium, beryllium. The uniqueness of oil from hemp seeds is due to a high (up to 80%) content of polyunsaturated essential fatty acids (linoleonic - 50-70% and linolic - 15-25%), which are necessary for normal functioning of human. Press cake contains 30-35% of protein, more 10% of fat and up to 25% of fibre; 100 g of this press cake corresponds to 73 fodder units. Phytin (calcium-magnesium salt of izon phosphoric acid) is an important component, which are widely used in medicine to stimulate hematopoiesis, promoting growth and development of bone tissue, as well as in certain diseases of the nervous system. The hemp stalks varieties of our selection contains up to 25.5-26.8% of fiber; 45.0-58.0 – cellulose, 24.0-26.0% lignin, that is in wood deficit conditions does not exclude the additional use of culture.
