Popis:	This article presents the results of a long-term field experiment at Rakican (Eastern Slovenia). Between 1993 and 2010, the temperature increased at a rate of 0.0288°C a−1, while average annual precipitation did not change, but showed great variation from year to year. In years with a higher average annual temperature, higher crop yields were achieved. Higher amounts of precipitation had a positive impact on yield at higher mineral nitrogen (N) rates, but a negative impact on yield in treatments with no mineral N. In systems with farmyard manure (FYM) and straw incorporation, maize yields increased in accordance with the increase in mineral N. Winter wheat yields increased with increasing mineral N to the N1 mineral N application rate with FYM application, and N2 with straw incorporation. Yields of winter barley increased in accordance with increasing mineral N until the highest N application rate (N3) with FYM application, and until N2 with straw incorporation. With regard to environmental compliance req...
