Weed suppression ability of spring barley varieties

Weed Research, 1995
SummaryThree years of experiments with spring barley showed significant differences in weed suppression ability among varieties. Weed dry matter in the most suppressive variety, Ida, was 48% lower than the mean weed dry matter of all varieties, whereas it was 31% higher in the least suppressive variety, Grit.

Biological Suppression of Weeds: Evidence for Allelopathy in Accessions of Cucumber

Science, 1974
Cucumber ( Cucumis sativus L.) accessions from 41 nations were grown with two indicator species in a search for superior competitors. Of the plant introductions tested, one inhibited indicator plant growth by 87 percent and 25 inhibited growth by 50 percent or more.

Low disturbance seeding suppresses weeds in no‐tillage soyabean

Weed Research, 2015
SummaryGermination is a key process in the dynamics of weed populations. In no‐tillage systems, crop seeding is often found to induce seed germination in the seeding strip. In this research, experiments to investigate options for reducing weed seedling establishment were conducted in no‐till soyabean fields located in two sites in south Brazil. A first

The effect of cover plants on weed suppression

Glasilo biljne zaštite, 2020
Otkako je utvrđen negativan učinak intenzivne poljoprivrede na okoliš, bioraznolikost i zdravlje ljudi, znanstvenici istražuju mogućnosti „redizajniranja“ uzgoja bilja koje bi bile prihvatljive u održivom sustavu proizvodnje. Uz ostale alternativne mjere, pokrovne kulture (češći naziv zelena gnojidba) su na svjetskoj razini, zbog svoje višestruke ...

[Weed-suppressive effect of phenolic acids].

Ying yong sheng tai xue bao = The journal of applied ecology, 2006
Allelochemical substitutions salicylic acid, p-hydroxybenzonic acid, cinnamic acid, vanillic acid and ferulic acid were tested in a gyrating regression experiment to study the weed-suppressive effect of phenolic acids on the root growth of barnyardgrass.

Wildfire Suppression—A Paradigm for Noxious Weed Management

Weed Technology, 1995
The spread of noxious weeds on rangeland and forests in the United States has been described as a raging biological wildfire. This analogy applies to aspects of spread, impact, and control of weeds. Patterns and means of spread are similar. Noxious weeds and wildfires can dramatically change natural plant communities, alter distribution and species ...

Weed suppression and crop production in annual intercrops

Weed Science, 2005
Abstract Intercrops have been associated with greater yields and pest and weed control compared with sole crops. In this field experiment, we investigated agronomic performance and weed suppression by three crops—spring wheat (Triticum aestivum), canola (Brassica napus), and field pea (Pisum sativum)—alone and in all possible combinations at two sites ...

Study the Use of Compost Tea in Weed Suppression

International Journal of Environmental Research, 2018
Applying compost tea, prepared by aeration, without or with water hyacinths by either water or solvent extraction, showed phytotoxic in practice of suppress weed. Compost tea extracts had influential inhibition based on its concentrations after 24 h brewing on Zea mays and P. oleracea seed germination and seedling growth.

Efficacy of rhizobacteria in suppressing weed growth

Concilium
The production of bioherbicides from isolates of deleterious rhizobacteria capable of suppressing plant growth is a sustainable method for weed management. The objective of this research was to evaluate whether rhizobacteria that potentially inhibit plant growth interfere with the growth of weeds.
