| Evaluation of the usefulness of six common winter wheat varieties (Kobra, Roma, Korweta, Sukces, Zyta, Mewa) and one variety (Schwabenkorn) of spelt winter wheat (Triticum spelta) for cultivation in organic farming was the aim of the research. The research was based on a special field experiment established in 1994 on a grey-brown podzolic soil in which different crop production systems (organic, integrated and conventional) are compared. The research was conducted between 2002 and 2004 on the field of winter wheat in the organic system. The following parameters were taken into account in the research: Leaf Area Index, nitrogen nutrient status and grain yield. Average grain yields of winter wheat independently of the year and variety amounted to 4.36... |

| Intensity of leaf infestation by selected fungal pathogens and yielding of old winter wheat cultivars (Ostka Kazimierska, Kujawianka Więcławicka, Wysokolitewka Sztywnosłoma) against a background of modern winter wheat cultivars (Kobra, Roma, Korweta, Sukces, Zyta, Mewa) in conditions of organic farming was assessed. The research was based on a special field experiment established in 1994 year on a grey-brown podzolic soil in which different crop production systems are compared. The research was conducted in 2005 and 2006. Average for 2 years grain yield of winter wheat for all cultivars amounted to 3.0 t/ha. In both years the largest yields were noted for modern winter wheat cultivars. Old cultivars of wheat reacted better on water deficiency than modern... |
