A laboratory experiment was conducted at the plant physiology division, Bangladesh Agricultural Research Institute (BARI) during 2019-20 to assess the allelopathic effects of some selected weed species on seed germination and seedling growth of mungbean. Four weed species viz., Durba (Cynodon dactylon), White cock’s comb (Celocia argentia), Shyama (Echinochloa crusgalli), Shak notae (Amaranthus viridis) were used for mungbean (BARI Mug 6). Boiled and un-boiled weed extracts reduced the germination and primary growth of mungbean. The ranking of weed species in respect of inhibitory effect on se

An advantage of tarping is that it enables growers to control weeds without herbicides or tillage equipment, which can be cost-prohibitive for small-scale growers. Tarping is also

AbstractCultural practices such as tillage used for crop production influence the composition of the weed seed bank in the soil. In order to investigate the effects of different tillage methods on seed bank properties, species diversity and similarity, two laboratory and greenhouse experiments were carried out as randomized complete block design with four replications in 2011. Treatments included: once tillage per year (T1), twice tillage per year (T2), more than twice tillage (T3) and no tillage (T4). Laboratory results showed that the T3 and T4 treatments had the highest and the lowest obser

Abstract:

Broomrapes (Orobanche and Phelipanche species) are holoparasitic weeds that infect roots of crop hosts from Asteraceae, Brassicaceae, Apiaceae, Fabaceae, and Solanaceae. The parasitic weeds are difficult to control selectively without crop damage once attached to their roots. Identification of natural compounds with herbicidal activity against pre-attached broomrape stages can provide control alternatives. With the aim to identify plant species with efficacy for broomrape control, organic and residual aqueous phase extracts from roots of seventeen weed species common in south Spanish broomrape

Abstract:

Over the last couple of years, the production of cow pea has declined dramatically due to lack of quality seeds, poor germination, uneven plant stands, insect pest problems, and improper storage techniques. To ensure sustainable good crop growth and productivity, it is imperative to develop a judicious and comprehensive package of crop-specific seed management technologies, involving seed germination, vigour enhancing treatments, and seed protection treatments. A new approach to improve seed performance is to value-add plant-based extracts i.e., ethnopharmacological weed extracts at low doses,

Jerusalem artichoke has been reported to colonize several ecological niches and agronomic crops in southern Europe. This plant is also of interest because of its high biomass production and its potential to produce ethanol for biofuel. Allelopathy may be an advantageous trait in Jerusalem artichoke under cultivation, as it potentially reduces weed interference with the crop, theoretically allowing a reduction of mechanical or chemical input required for weed management. However, this trait may also be unfavorable if other crops are cultivated in rotation with Jerusalem artichoke or in areas in

Weeds cause significant yield losses in crop production and influence the health of animals and humans, with some exotic weeds even leading to ecological crises. Weed control mainly relies on the application of chemical herbicides, but their adverse influences on the environment and food safety are a significant concern. Much effort has been put into using microbes as bioherbicides for weed control. As plant-associated bacteria (PAB), they are widely present in the rhizophere, inside crops or weeds, or as pathogens of weeds. Many species of PAB inhibit the seed germination and growth of weeds
