Studies Regarding the Influence of Crop Rotation and Regime Nutrition Interaction on Phytomass Accumulation in Winter Wheat Cultivated on the Preluvosoils

The crop rotation is a decisive factor influencing growth and development of wheat. Plant growth is fundamental in obtaining yield and is related vegetation and technological factors, the level of yield being reflected in the intensity of phytomass accumulation. In the majority of cases, total growth of green mass is considered on the assumption that a maximum yield is obtained by increasing total dry weight phytomass production and by a favourable repartition of it among plant’s organs. Bilteanu Gh., (1993) after long tests demonstrated the importance of crop rotation on wheat yields on brown-red soils in Romanian Plain. On clay-illuvial podzols, the introduction of ameliorative plants such as red clover represented an element of outmost importance for increase of the wheat yield.
