Crop productivity under increasing nitrogen rates and different organic fertilization systems in a long-term IOSDV experiment in the Czech Republic

Popis výsledku v původním jazyce

The yields of winter wheat, winter barley, and potatoes in a long-term field experiment on one of the international IOSDV network sites, were evaluated. The experiment was set up in 1983 in Lukavec, Czech Republic, within a potato growing region on a sandy-loam soil. The experiment includes three systems of organic fertilization: Without manure; manure added for the potatoes; and cereal straw ploughed-down, in combination with increasing nitrogen (N) rates from 0-160 kg N ha-1 or 0-200 kg N ha-1, for cereals and potatoes, respectively. The results of two rotations, during the years 2002-2007, were analyzed. Nitrogen rates had a strong effect on the yields of all crops (p < 0.001). The highest average yields of the cereals 7.2-7.4 t ha-1 (wheat), and 5.2-5.5 t ha-1 (barley) were attained with nitrogen rates of 120 or 160 kg ha-1. With potatoes the highest yields of 46-54 t ha-1 were observed with 150 or 200 kg N ha-1. The yield differences between the two highest N levels were small and
