THE INFLUENCE OF FERTILIZER DOSES ON THE PRODUCTION OF POTATOES IN SFANTU GHEORGE, COUNTY OF COVASNA

The purpose of the fertilization experiments, described in this paper, is to establish some optimal and economical doses of NPK fertilizers, while taking into consideration the soil`s supply in fertilizing elements, with the purpose of determining the influence of different doses of fertilizer on the production and efficiency of potato crops. In this context, the amount of the administered chemical fertilizer was between 250 to 550 kg of active substance/ha, out of which the nitrogen doses were of 0, 100, 200 and 300 kg of active substance/ha. This paper only focused on carrying out some research on the physical and chemical conditions of agricultural lands, and can be further developed around this subject.Â
