Effects of mineral nutrition efficiency of wheat have been studied at the stationary field trial of the Institute of Field and Vegetable Crops in Rimski Šančevi (Serbia) for two years (2008/09 and 2009/10). In this paper, average yields from 20 treatments of increasing doses of nitrogen, phosphorus and potassium nutrients are presented and the agronomic efficiency of applied nutrients is calculated. Nitrogen had a most significant impact on the yield of wheat. The largest yield increase with the one kilogram of nutrients applied was with nitrogen (on average for two years 32.20 kg grain/1 kg of N applied), phosphorus (10.52 kg grain/kg P2O5), and lowest for potassium (5.85 kg grain/kg K2O). Agronomic efficiency of nitrogen tended to decrease with increasing amounts of N-nutrients applied. The best efficiency of applied nitrogen fertilizers was on tretment with 50 kg N/ha.
