Natural fibre based composites are being used more frequently in the automotive industry because of their positive characteristics. Fibres currently used and mostly imported to Europe do not sufficiently meet all the demands for natural fibres. As a new fibre plant velvetleaf (Abutilon theophrasti) has been taken into consideration. However, there...

... tested accessions of velvetleaf differed in all tested characteristics except fibre content. Accession H5 had the shortest plants among all accessions tested in both experimental years (Fig. 4 A). This accession also had strong branching and a high number of seed-filled capsules (data not shown). Plant height was highest in accessions H6 and H7 in 2016 (202 and 197 cm), and also for H7 in 2017 (188 cm). This is also reflected in the biomass yield in both experimental years where H7 showed high yield in 2016 and the ...

This is also reflected in the biomass yield in both experimental years where H7 showed high yield in 2016 and the significantly highest yield in 2017 (11.8 and 8.4 t ha -1 DM, respectively; Fig. 4 B). The highest yield in 2016 was shown by the accession H1 (12.1 t ha -1 DM). The biomass yield for accession H5 was 39% lower (2016). Also accession H3 showed significant low biomass yields of 8.0 and 6.4 t ha -1 DM in 2016 and 2017, respectively. In 2017 differences in biomass yield were smaller than those in 2016, so biomass yield of ...

Therefore, the same significant differences as for biomass yield (2016) were obtained for fibre yield in 2016 (Fig. 4 D). The fibre yield ranged between 879 and 1,515 kg ha -1 DM (H5 and H7, respectively).

This study presents the results of 3-year field trials, whose purpose was to assess the dynamics of dry matter accumulation by maize depending on the placement depth of a two-component (NP) mineral fertilizer in the soil layer, type of nitrogen fertilizer and date of its application. Weather conditions, mainly thermal in the early growing season, h...

The species has regained interest as a fiber crop [7,11], taking up one of its old uses in Asia and for a short time in the USA, aside from its use as a medicinal plant [1,12]. In China and Kashmir, the seed is a valuable food because of its high protein content [2,8,9,13]. ...

Abutilon theophrasti's Resilience against Allelochemical-Based Weed Management in Sustainable Agriculture-Due to Collection of Highly Advantageous Microorganisms? Plants 2023, 12, 700. Abstract: Abutilon theophrasti Medik. (velvetleaf) is a problematic annual weed in field crops which has invaded many temperate parts of the world. Since the loss of crop yields can be extensive, approaches to manage the weed include not only conventional methods, but also biological methods, for instance by microorganisms releasing phytotoxins and plant-derived allelochemicals. Additionally, benzoxazinoid-rich rye mulches effective in managing common weeds like Amaranthus retroflexus L. have been tested for this purpose. However, recent methods for biological control are still unreliable in terms of intensity and duration. Rye mulches were also ineffective in managing velvetleaf. In this review, we present the attempts to reduce velvetleaf infestation by biological methods and discuss possible reasons for the failure. The resilience of velvetleaf may be due to the extraordinary capacity of the plant to collect, for its own survival, the most suitable microorganisms from a given farming site, genetic and epigenetic adaptations, and a high stress memory. Such properties may have developed together with other advantageous abilities during selection by humans when the plant was used as a crop. Rewilding could be responsible for improving the microbiomes of A. theophrasti.
