Abstrakt
The aim of the study was to assess the competitive potential against weeds and grain
yield of spelt wheat (Triticum aestivum ssp. spelta) as compared to varieties of common wheat
(Triticum aestivum ssp. vulgare) under organic farming conditions. The study was conducted in
the years 2005–2007 at the Experimental Station of IUNG – PIB in Osiny (Lublin province), on a
field used in organic way since 1994. The varieties of spelt wheat: Schwabenkorn (2005 and
2007) and R12 (2006) and varieties of common wheat: Kobra, Mewa, old variety Ostka
Kazimierska were cultivated. Species composition, number of weeds and their dry matter were
assessed in tillering and dough stage. Biometric analysis of wheat plants and plant canopy
architecture were also done. The smallest dry matter of weeds in dough stage was recorded in
spelt wheat Schwabenkorn, old variety of common wheat – Ostka Kazimierska and modern
variety – Mewa. High competitive potential against weeds of spelt Schwabenkorn and Ostka
Kazimierska was associated with the morphological features such as the biggest height,
tillering, leaf area and leaf area index (LAI). The smallest ability to compete with weeds and the
higher level of weed infestation was noted in Kobra and spelt R12. Despite of the favorable
parameters of growth and development of spelt Schwabenkorn and Ostka Kazimierska,
affecting their competitiveness against weeds, they have small yielding potential. The average
grain yields of modern varieties: Kobra and Mewa were about 4 t · ha–1 in organic system.
