Winter wheat grain yield as influenced by crop rotation (I), manure application (II) and mineral N rate (III) in the long-term field experiment at Grabow, Poland. Error bars denote standard deviations (n = 4). LSD(P ≤ 0.05): for I = 0.34, II = 0.30, III = 0.29, Interactions: I x II and I x III = not significant, II x III = 0.40.
