Název v původním jazyce

Root system production and aboveground biomass production of chosen cover crops

Popis výsledku v původním jazyce

The most planted cover crops in the Czech Republic are white mustard (Sinapis alba L.) and phacelia (Phacelia tanacetifolia Benth.). A field trial was executed to evaluate root system size (RSS) in eight varieties of mustard and five varieties of phacelia on two locations, in three BBCH phases and in two years. The relationship between RSS and aboveground biomass was inquired. The root system size was assessed by measuring its electric capacity. Aboveground biomass and root samples to be evaluated by means of a digital image analysis were recovered in the BBCH phase 70. The yield of aboveground biomass of mustard was always statistically significantly higher than that of phacelia. Mustard showed a statistically significant negative correlation betweenroot length density (RLD) within 10 cm and aboveground biomass weight (r = -0.46*). Phacelia featured a statistically significant correlation between aboveground biomass production and nitrate nitrogen content in soil (r=0.782**).
