Weed suppression by cereals: Beyond ‘competitive ability’

Weed Research, 2023
Abstract Much research on cereal‐weed competition has been directed towards finding cultivars that have high ‘competitive ability’ with weeds. I argue that this objective is insufficient, because weed suppression is usually the result of interactions among genotype, environment and management rather than direct effects of genotype ...

Mycorrhizal fungi suppress aggressive agricultural weeds [PDF]

Plant and Soil, 2009
Plant growth responses to arbuscular mycorrhizal fungi (AMF) are highly variable, ranging from mutualism in a wide range of plants, to antagonism in some non-mycorrhizal plant species and plants characteristic of disturbed environments. Many agricultural weeds are non mycorrhizal or originate from ruderal environments where AMF are rare or absent. This

High Seeding Rates and Low Soil Nitrogen Environments Optimize Weed Suppression and Profitability in Organic No-Till Planted Soybean

Frontiers in Agronomy, 2021
No-till planting crops into rolled-crimped cover crops can improve soil health while reducing labor and fuel requirements compared with traditional tillage-based production. However, little information is available to help farmers optimize the management

Weed Functional Diversity as Affected by Agroecological Service Crops and No-Till in a Mediterranean Organic Vegetable System

Plants, 2020
This paper explores the effect of agroecological service crops (ASCs), i.e., crops included in the crop rotation for their ecosystem services, terminated with an in-line tillage roller crimper (ILRC) on weed community composition and their functional ...

Effect of multi‐tactic weed management on weed suppression and yield in the establishment year of intermediate wheatgrass

Agrosystems, Geosciences & Environment, 2023
Intermediate wheatgrass [Thinopyrum intermedium (Host) Barkworth & Dewey] (IWG) is a new perennial grain crop that can be harvested for multiple years.

Weed Suppression in Only-Legume Cover Crop Mixtures

Agronomy, 2019
Weed suppression is a potential benefit of cover crop mixtures, as species diversity may allow for combining early and late-season competition with weeds.

Weed dynamics and productivity of wheat (Triticum aestivum) under various tillage and weed management practices

The Indian Journal of Agricultural Sciences, 2023
The reduced yield under conventional tillage is due to more crop-weed competition and more dry matter accumulation by the weeds (Kumar et al. 2018).

Herbicide and nitrogen rate effects on weed suppression, N uptake, use efficiency and yield in winter oilseed rape (Brassica napus L.)

Global Ecology and Conservation, 2019
Improved weed management strategies are imperative in oilseed rape production. Herbicide and nitrogen (N) fertilization could be integrated into weed management as these are known to affect weed emergence and growth.

Are No-Till Herbicide-Free Systems Possible? A Simulation Study

Frontiers in Agronomy, 2022
Conservation agriculture (CA) allows farmers to reduce costs and enhance soil health, but tends to increase weed infestation and associated crop yield loss, and/or herbicide use.

Evaluating Chemical Suppression Treatments to Alter the Red: Far-Red Ratio in Perennial Groundcovers for Maize Production

Agronomy, 2022
Perennial groundcover (PGC) has great potential to deliver ecosystem service benefits and control weeds in annual row crop systems. Inadequately suppressed PGC, however, acts as an early-season weed, causing a shade avoidance response (SAR) in maize (Zea
