Megjegyzések:	In non-irrigated treatment the maximum yields of winter wheat were 5590 kg ha-1 in biculture (maize-wheat) and 7279 kg ha-1 in triculture (peas-wheat-maize) in 2007 year characterized by water-deficit stress. In 2008 (optimum rain amount and distribution) the maximum yields were 7065 kg ha-1 (biculture) and 8112 kg ha-1 (triculture) in non irrigated conditions. The fertilization surpluses of wheat were 2853-3698 kg ha-1 (non- irrigated) and 3164-5505 kg ha-1 (irrigated) in a dry cropyear (2007) and 884-4050 kg ha-1 (non-irrigated) and 524-3990 kg ha-1 (irrigated) in an optimum cropyear (2008). The optimum fertilizer doses varied N150-200+PK in biculture and N50-150+PK in triculture depending on cropyear and irrigation. The optimalization of agrotechnical elements provides 7,8-8,5 t ha-1 yields in dry cropyear and 7,1-8,1 t ha-1 yields of wheat in good cropyear, respectively. Our scientific results proved that in water stress cropyear (2007) the maximum yields of maize were 4316 kg ha-1 (monoculture), 7706 kg ha-1 (biculture), 7998 kg ha-1 (triculture) in non irrigated circumstances and 8586 kg ha-1, 10 970 kg ha-1, 10 679 kg ha-1 in irrigated treatment, respectively. In dry cropyear (2007) the yield-surpluses of irrigation were 4270 kg ha-1 (mono), 3264 kg ha-1 (bi), 2681 kg ha-1 (tri), respectively. In optimum water supply cropyear (2008) the maximum yields of maize were 13 729-13 787 (mono), 14 137-14 152 kg ha-1 (bi), 13 987-14 180 kg ha-1 (tri) so there was no crop-rotation effect. We obtained 8,6-11,0 t ha-1 maximum yields of maize in water stress cropyear and 13,7-14,2 t ha-1 in optimum cropyear on chernozem soil with using appropriate agrotechnical elements.
