Research on efficiency of mineral nutrition of winter wheat in three production years were carried out on long-term field experiment at the Institute of Field and Vegetable Crops at Rimski Šančevi, Novi Sad, Serbia. This paper presents the results about effects of mineral nutrition on grain yield of winter wheat in 20 different fertilization treatments with increasing rates of nitrogen, phosphorus and potassium, and agronomical use efficiency of the applied fertilizers. As expected, nitrogen had significantly highest impact on the wheat yield. The highest increase in the grain yield with one kilogram of the fertilizer used was with nitrogen (33.89 kg of grain/1 kg of N, in average for three years), followed by phosphorus (9.11 kg of grain/1 kg of P2O5), and potassium (3.01 kg grain/1 kg of K2O). Agronomical nitrogen use efficiency differed depending upon weather conditions of the year, but in all analysed years as well as in average, it had tendency to decrease if intensity of fertilization increased.
