In the period 20 9-202 , the effect of different doses of complex fertilizers of the 6: 6: 6 type applied alone and together with some foliar fertilizers of the Fertil Star and Aurora types on the production, quality and accumulation of some nutrients in the leaves of the ʻFlorinaʼ apple variety was monitored, cultivated on a cambic faeziom soil type from Mehedinți. The productions were obviously marked by the complex application of the 3 macroelements, being between 20.35 t/ha and 25.6 t/ha. A clear influence of fertilization on the total dry matter content was found, between - 7%, the increase being directly proportional to the intake of nutrients from the applied fertilizers. High concentrations of K cause their acidity to increase, which has the consequence of changing the ratio of sugar/organic acids and finally changing the taste in the sense of increasing the flavor. Nutrient elements in the leaves changed favorably as a result of the application of doses and types of fertilizer.
