Abstract

The field trial was conducted over the period 2000-2005 at the RIPP in Piešťany in Western Slovakia. The purpose of the study was to investigate yield and yield components of spring barley undersown with red clover growing in ecological and low input systems. In the six year crop rotation pattern, incorporation of straw, crop residues, catch crops for green manure and farmyard manure was used. The effects of farming systems were assessed by evaluating the yield and yield components of spring barley. Grain yields, calculated from the mean values achieved in the six year study period, were significantly differed between ecological (4.8 t ha-1) and low input (5.02 t ha(-1)) systems. The influence of the cropping systems on grain yield of spring barley, number of kernels per spike, thousand of kernels weight and spike length was remarkable with the exception of straw yield, number of spikes per m-2 and weight of kernels per spike.
