The Farm-to-Fork strategy was the starting point for this study. Farmers in Romania and other member states expect a decrease in agricultural production in the main crops, due to the reduction of the quantities of fertilizers and pesticides allowed to be used. The article aims to highlight these quantities currently used, as well as the correlation with the realized productions, before the application of the mentioned strategy. The sunflower farming system was the object of the analysis, for which purpose the cultivated areas and the productions obtained in Romania were studied and compared to those in Germany, Spain, France, Italy, Hungary and Poland. It was found that in Romania, in the period 2010–2019, small amounts of fertilizers and pesticides were applied. Romania occupies the last position among the countries under analysis, both in terms of fertilizers and pesticides. To obtain a ton of sunflower in Romania, the nitrogen fertilizers used were 19.2 kg N active nutrient, with a negative deviation of −45.5 kg N active nutrient compared to Germany. The P2O5 phosphorus fertilizers used in Romania represent 7.48 kg of the active phosphorus nutrient with a negative deviation of −13.09 kg/ha compared to Spain. Potassium fertilizers used in Romania comprise 2.68 kg of active potassium nutrient used to obtain a ton of sunflower and have a negative deviation of −22.66 kg/ha compared to Poland. The pesticides used in Romania for sunflower cultivation represent 0.35 kg total pesticides used per ton and have a negative deviation of −2.48 kg compared to Spain, the largest consumer. In the event that a unit reduction of 50% for pesticides and 20% for fertilizers is applied, according to the Farm to Fork Strategy, the impact will be unequal on the productions obtained, both quantitatively and qualitatively.
