The paper is based on the results researches obtained during 2004 – 2006 in Oradea. In the crop rotation of 4 years with clover in comparison with wheat – maize crop, the yield gains statistically assured were obtained both in the variants with organic fertilization and in the variant with organic + chemical fertilization. The use of the mixture lupine + oat in this crop rotation determined to obtain yield gains in comparison with variants with lupine, pure crop as green manure; yield obtained using lupine + oat were close to the yield from variant with manure 25 t/ha. Meliorative crop rotation and fertilization determined the improve of the water use efficiency in comparison with the controls; water use efficiency from variants with lupine + oat was bigger than water use efficiency obtained in the variant with lupine, too.
