Biomass production of white mustard (Sinapis alba L.) varieties in relation to the root system size

Popis výsledku v původním jazyce

Root system size (RSS) of eight white mustard varieties was evaluated in a field trial. The two-year experiment was conducted on two different agro-ecological sites in the Czech Republic: Troubsko and Horní Třešňovec. RSS was measured during the vegetation period by the electrical capacity method. At the end of vegetation the above ground biomass and root samples were evaluated by digital image analysis. There was no statistically significant relationship between RSS and amount of aboveground biomass. Relationship between RSS and content of NO3- and NH4+ ions in the soil after harvest was observed. RSS negatively correlated with the content of nitrate nitrogen in the soil, however, the correlation was statistically not significant. Evaluation across sites revealed a positive correlation between aboveground biomass and amount of residual NO3- ions in the soil (r=0.54). On the other hand a significant negative correlation (r=-0.81) of RSS and NH4 + ions content was observed in Troubsko.
