The Transylvanian hillock area is geographical characterised through a wave like landscape, sunny slopes with no forest vegetation, frequently exposed to different forms of erosion. The pedogenetical cover on these slopes are represented by regosoils, erodisoils, soils with low trophicity, for agricultural usage. A very well adapted specie for these conditions is Hippophae rhamnoides. Hippophae rhamnoides is considered to be one of the most valuable specie of brushes from our spontaneous and cultivated flora, appreciated in different domains such as pharmacology, food industry, animal feeding, forestry and even in landscaping. Its fruits contain over 20 substances with an important role in the regularization of the metabolism of the humans, having both a therapeutical and curative role in preventing and treating eye diseases, skin problems, avitaminoses, diseases of the neural system, endocrine system etc. It is a unisex dioical plant, of 1,5-3,5 m (in some areas can reach up to 8-10 m). It produces fruits after three years from planting and it has a biological life of 18-20 years. It is a plant with a high adaptability, being one of the best colonizing plants. It valorizes the lands with different types of soil, wet and dry, with different textures (from sandy to clay), especially the sands from the river banks. With a powerful root system, it expands rapidly as it rots can go up to 20 m. The planting distance is 3x2m, in the plain conducting way, or 3,5x2,5 m in the classical conducting way. For polenisation at planting, one must respect the percent of 1 male plant to 6-8 female plants. It has a very high growth in the years 3-5 when it produces great amounts of branches, and having a production of 3-12tones/ha, and at maximum it has a production of 25 tones/ha.
