The influence of competitive interactions between spring wheat and the undersown Persian clover, as well as the diversified density of plants, on the stomatal conductance and intensity of the processes of photosynthesis and transpiration in both species was evaluated during a pot experiment conducted between 2010 and 2012. The spring wheat and Persian clover cultivation methods – puresowing, cultivation...
The paper presents the results of a 3-year-long (2008–2010) study on the dynamics of weedinfestation of spring barley sown after different previous crops (potato, spring wheat and springbarley, in 1- and 2-year sequences of the same crop) in four-field crop rotation systems with 25, 50 and75% shares of spring barley. Weed infestation was evaluated at the barley tillering stage and beforeharvesting,...
