The aim of the present research was to compare the residual effect of six undersown crops cultivated on the light soil on the yielding of spring barley. The field experiment was carried out in the years 1993-97 at the Experimental Station of Bezek near Chelm (Poland). The static field research was carried out by split-plot method in four replications. The field experiment included six undersown crops: serradella Bydgoska 40 kg/ha, white clover Podkowa 10 kg/ha, red clover Hruszowska 20 kg/ha, hop trefoil Renata 15 kg/ha, white melilot Selgo 20 kg/ha, Dutch ryegrass Motycki 40 kg/ha planted into four cereal crops: winter rye Dankowskie Zlote (240 plants per square m), winter triticale Presto (350 plants per square m), spring barley Rudzik (230 plants per square m) and oat Dragon (400 plants per square m) and control treatment. Residual spring barley was cultivated after undersown crops. Undersown crops did not affect grain yield of spring barley. Oat increased grain yield of spring barley. Unfavourable water balance decreased grain yield of spring barley
