Abstract


In Romania, in present there is a large mediatization on the concept of organic farming following the idea to eat healthier, to use products from the farm and help the sustainability of rural area. Growing a variety with purple core, Blue Salad, in organic farming system represents an element of competitiveness for organic farming located in mountainous areas because it adapts easier to these areas and has superior quality compared to local varieties because it contains anthocyanins. Ecopedoclimatice conditions from mountainous area, Avram Iancu, determined high productions of the variety Blue Salad in system of organic farming, being similar to those from the center of origin Peruvian Andes. Cultivar Blue Salad prefers an acid soil (districambosoil) and colder areas placed at a high altitude than the ordinary potato varieties. For the growing of Blue Salad variety in organic farming system have been used organic fertilizers from our own farm (fermented manure, ashes, beech leaves) which on one hand improved fertility districambosoil and on the other hand increased the production independence with the variants of fertilization. Statistical data show an increase in production depending on the variants of fertilization, on the differentiated doses of manure applied as organic support, so, compared with the control sample (22.10 t/ha) have been highlighted significant increased productions at all fertilization variants with a maximum value of 27.03 t/ha to the variant with manure 30 t/ha + ashes 20t/ha.
