POTATO AND SUGAR BEET TECHNOLOGICAL QUALITY AS RESULTS OF DIFFERENT FERTILIZATION

In the agro-climatic conditions from Brasov area in the years 2014-2015, within the National Institute of Research and Development for Potato and Sugar Beet Brasov, were studied variants with NPK complex fertilizers applied for basic fertilization for potato crop by broadcast after furrow and at soil preparation before sowing at sugar beet crop. The basic fertilization was supplimented on all variants with a second fertilization with different forms of nitrogen. These fertilization technologies are adapted to the cultivation conditions in order to reach the maximum production potential in terms of quantity and quality and with guaranteed profitability for the two crops. In the case of sugar beet, the production on fertilization variants was analyzed qualitatively, the sugar content being strongly influenced by the fertilizer combinations used. Analyzing the technological quality of the potato, it was found a starch content decreasing in all fertilization variants.
