A field experiment was conducted in order to determine the influence of an organic and low input system on the yield and selected yield components of spring barley. The experiment was carried out during 2000-2005 on Luvi-Haplic Chernozem on an experimental station of the RIPP in Western Slovakia. Significantly higher yield of spring barley grain was found in the low input system (5.021 t per ha) compared to the organic system (4.801 t per ha). Similarly, the yield of dry matter, thousand of kernels weight and kernels per spike were significantly higher in the low input system. The yield of straw and evaluated yield components (number of spike per square m, kernel bulk density, and amount of kernels larger than 2.5x20.0 mm) were not influenced by used farming systems. Each investigated yield component was highly significantly influenced by weather conditions during the years. In spite of significantly higher grain yield in the low input system in comparison to the organic system, we recommend both cropping systems for spring barley growing under the studied soil-climatic conditions.
