Sugar beet yield loss predicted by relative weed cover, weed biomass and weed density
crop–weed interaction weed competition yield loss function
2017/4/6
Sugar beet yield loss was predicted from early observations of weed density, relative weed cover, and weed biomass using non-linear regression models. Six field experiments were conducted in Germany a...
Primary screening of potentially bio-active substances in the lyophilisate of Pectinatella magnifica biomass
bryozoan cell line L929 spreading specific growth rate
2015/5/25
The purpose of this research was to examine potential bio-active substances in the lyophilisate of
Pectinatella magnifica biomass and its focus was on primary screening of the biomass. Extracts of l...
Disturbance-induced changes in the plant biomass in forests near Plešné and Čertovo Lakes
aboveground biomass Picea abies forest stand damage Vaccinium myrtillus
2015/5/6
Two forested catchments in the Bohemian Forest (Šumava Mts.) were investigated according to the species composition of herb layer and aboveground plant biomass. The bark-beetle gradation was obse...
Secondary succession on an early abandoned field: vegetation composition and production of biomass
fallow-field ploughing weeds biomass monocotyledonous plants dicotyledonous plants perennial annual secondary succession
2015/1/28
During 1996–2000 the secondary succession on a field left fallow was investigated. The experimental area was divided into a ploughed and an unploughed part. Both parts were divided into 5 × 5 m plots ...
Biomass accumulation, weed dynamics and nitrogen uptake by winter cover crops in a warm-temperate region of South Africa
Biomass yield conservation agriculture cover crops weeds dynamics
2011/1/11
Production of large biomass yields and weed suppression from cover crops have been major constraints affecting success and uptake of conservation agriculture technologies by smallholder irrigation far...
