Abstract:

The aim of the study was to evaluate yields and selected qualitative parameters of spring barley cultivated after three preceding crops (sugar beet, winter wheat, maize for grain) in the years 2003–2008. farm yard manure was added to the preceding crops at a dosage of 40 t ha-1. A long term stationary field experiment was established on loamy luvi-haplic chernozem in south-western Slovakia. Statistically higher yields were recorded after sugar beet (5.38 t ha-1) than either maize for grain (4.77 t ha-1) or winter wheat (3.54 t ha-1). TGW was statistically significantly higher after maize for grain (43.82 g) compared with winter wheat (42.46 g) and sugar beet (40.93 g). The highest protein content (** P  0.01) was found in the barley crop after sugar beet (12.64%), followed by winter wheat (11.02%) and maize for grain (10.56%). Kolbach’s numbers were statistically higher after winter wheat (37.30) than either sugar beet (35.88) or maize for grain (36.12). The extract and starch content was not statistically influenced by the preceding crop.
