The results of the researches performed between the years 2006 – 2009 on a cambic low gleyed chernozem from the Banat Plain showed that the wheat cultivated in monoculture gives productions with 59-81% lower than that cultivated in crop rotation with other plants during 2-4 years. In maize, the yield obtained in monoculture is situated behind that obtained in crop rotation with 11-21%. The most favorable crop rotations for wheat were rape-wheat in a 4 years rotation and soybean-wheat in simple rotation of 2 years. In maize, the most favorable was the 2 years rotation (wheat-maize). The mineral fertilization was very efficient both in wheat (11-36%) and maize (9-31%). The organic fertilization with manure was very efficient for maize, the yields being superior with a mean value by 34% for a 60 t/ha dose and with 16% for 30t/ha. The fertilization compensates the negative effect expressed by the monocultivation only in a small measureapplication/pdfmonocultivationcrop rotationmineral and organic fertilizationcambic gleyed chernozemyieldfolyóiratcikkOpen Accesshttps://doi.org/10.34101/ACTAAGRAR/I/8366Acta Agraria DebreceniensisIActa agrar.
