Weed biomass in cereals depending growing in pure stand or mixtures

Summary in the original language of the document

There started field experiments at State Priekuli Plant Breeding Institute, in cooperation with other Nordic countries research institutes from Denmark, Germany, Poland, Sweden and Finland, to fulfil tasks of Core Organic Plus project 'Weeds and Biodiversity'(PRODIVA). One of the research project hypothesis was based on the assumption that crop and variety mixtures have greater suppressive abilities against weeds than the sole crop and variety. The first results confirm this. Between the three studied oat varieties best weed suppresion show variety 'Kalli'; among the four tested spring barley varieties-'Maali’.
