Název v původním jazyce

Effects of seed rate and nitrogen fertilisation on cereal canopy characteristics.

Popis výsledku v původním jazyce

A detailed evaluation of the development and structure of winter wheat and spring barley stands was performed in small plot field experiments established at two locations in Central and South Moravia within the period of three years (2005 to 2007). A possibility of compensation of a reduced number of plants by nitrogen application was demonstrated in both crops. An increased density of plants and a lack of nitrogen accelerated and intensified the differentiation of tillers. The differentiation of tillers to productive and non productive ones could be identified on the basis of local minima in histograms illustrating the frequency of their weight distribution. This enabled to estimate the proportion of productive and non productive biomass in the totalabove ground biomass as an important indicator of effectiveness of farming inputs into the crop cultivation. Positive correlations between the total above ground biomass and its content of nitrogen and the biomass of potentially productiv
