The paper is based on the researches carried out in an experiment set up in 1990 in Oradea, on a preluvosoil. The experience has two factors – factor A is crop rotation (a1 – wheat monocrop, a2 – wheat, maize; a3 – wheat – maize - soybean) and the B factor is the water regime (b1 – unirrigated, b2 – irrigated) with maintaining the soil water reserve between the easily available water content and field capacity on watering depth (0 – 50cm). The researches carried out between 2005 – 2007 have shown the smallest of the gross protein content, wet gluten, dry gluten, deformation index and fall index registered in the wheat monocrop. In the wheat-maize crop rotation the values of the quality indexes have improved, the differences were statistically assured. The biggest values of these indexes were obtained in the wheat – maize – soybean crop rotation, the differences when reported to monocrop being very significant in all the studied years, in the conditions in which, in the durable agricultural system is the central pivot, and the researches carried out show the importance of the crop rotation with a large number of plots and the importance of the soybean crop as a forerunner for wheat, it’s effects being positive on the both on the quantity and the quality of the wheat yield, as well as the protein, dry gluten, wet gluten content, fall index and the deformation index.
