Inhoud: Impact of pesticides and plant nutrition on wheat crop, as well as their interaction was studied in a small plot field trial run at the experimental site on eutric cambisol type soil, in 2006 and 2007. The results obtained suggest, that treatments applied – both the increasing rate of fertilizers (N0P0K0, N40P100K100, N80P100K100, N120P100K100, N160P100K100) and the increasing intensity of pesticide application (Ø, herbicide, herbicide+ fungicide, herbicide+ fungicide+ insecticide) – had significant effect on the grain yield of wheat. In case of fertilizer application each N rate resulted in a further significant yield increase in the average of pesticide applications. In 2006 the minimum yield was 2.2 t ha-1, the maximum 5.5t ha-1, and the average 4.3 t ha-1. In 2007 the minimum yield was 1.00 t ha-1and the maximum 4.6 t ha-1the average 3.2 t ha-1. In accordance with the increment of the level of plant nutrition and plant protection applications a decreasing magnitude of yield increase was observed. Plant nutrition applications had a more definite effect on yield figures in comparison with that of plant protection treatments. Meteorological conditions of the crop years studied were considerably buffered by agronomic applications applied.
