The Performance of Oat-Vetch Mixtures in Organic and Conventional Farming Systems

The research aimed to compare the yields and yield components of mixtures oats with common vetch grown for seeds in organic conventional farming systems. Moreover, selection oat cultivars mixture its performance a crop rotation experiment different growing years was analyzed. Additionally, leaf area index (LAI) relative content chlorophyll (SPAD) were assessed. field four-field or systems carried out 2012–2014 southern Poland. Common (Vicia sativa L., cv. ‘Hanka’) mixed one two (Avena L.) cultivars, ‘Celer’ ‘Grajcar.’ effects all factors on mixtures’ canopy indices found. canonical analysis revealed that weather course, especially drought, had largest effect oat-vetch performance. developed highest LAI (5.28 m2∙m−2) seed (4.57 t ha−1) system. On contrary, share 24% higher system than one. ‘Grajcar’ increased by 16.5%. In summary, balanced depends proper cultivar,
