Wpływ wieloletniego zróżnicowanego nawożenia na jakość plonów roślin w zmianowaniu

TL;DRAbstract

Over 1994–1998 research was conducted in order to define the effect of varied multiyear (since 1948) fertilization on the size and uniformity of plant organs constituting the yield, on the content of organic components and minerals. The research covered the roots and leaves of sugar beet, spring barley and winter wheat grain, spring rape seeds and green matter of red clover. Similarly, the effect of no fertilization and straw fertilization + NPK, NPK, manure and manure combined with: PK, NK, NP, NPK, NPK + Ca on most of the qualitative characters of all the plants in crop rotation were compared using the method of cluster analysis with objects agglomeration. It was observed that the effect of multi-year fertilization on qualitative characters in successive plants in crop-rotation was different. Fertilization with manure combined with NPK + Ca enhanced the size of sugar beet roots, 1000 grain weight in cereals and the content of protein, phosphorus and calcium in green matter of red clo
