  journal={Agronomy Journal},
Little is known about the mechanism of winter annual weed suppression by forage radish (Raphanus sativus L. variety longipinnatus) winter cover crops. Previous studies suggest that allelopathy from decomposing residue and competition due to rapid canopy development contribute to weed suppression by other Brassica cover crops. Four contrasting experimental approaches were used to identify the mechanism of weed suppression by forage radish cover crops. Results of a field based cover crop residue…

Weed Suppression in Cover Crop Monocultures and Mixtures

The results suggest that cover crop mixtures require only low seeding rates of aggressive grass species to provide weed suppression, which creates an opportunity for other species to deliver additional ecosystem services, though careful species selection may be required to maintain mixture diversity and avoid dominance of winter-hardy cover crop grasses in the spring.

Spring- and Fall-Seeded Radish Cover-Crop Effects on Weed Management in Corn

Radish cover crops generally did not improve management of weeds during the corn growing season, but in the absence of a false seedbed, fall-seeded radish reduced field pennycress density and horseweed density in spring in site years where these weeds were present.

Cover Crop Impact on Weed Dynamics in an Organic Dry Bean System

Using SEM, one causal relationship between cover-crop N content and weed biomass at the first flower stage (R1) is identified, as mediated through soil N at the time of dry bean planting and at the stage with two fully expanded trifoliates.

The Importance of Species Selection in Cover Crop Mixture Design

Abstract Cover crops are increasingly being included in crop rotations as a mechanism to promote diversity and provide agroecosystem services, including weed suppression. Recently, cover crop

Impact of Diverse Annual Forage Mixtures on Weed Control in a Semiarid Environment

It is suggested that cropping with multiple species (particularly forage radish) may be an effective way to control weeds in semiarid environments.

Underseeding clovers in winter wheat may effectively manage weeds and, if they winterkill, can replace the need for tillage to control weeds after wheat harvest.

Are Cover Crop Mixtures Better at Suppressing Weeds than Cover Crop Monocultures?

Results of this study suggest that when weed suppression is the sole objective, farmers are more likely to achieve better results planting the most weed-suppressive cover crop as a monoculture than a mixture.

Biomass Production of an Overwinter Cover Crop with Biofumigation Properties in New Mexico

Results suggest that a fall-seeded mustard cover crop that is tilled into the soil in early spring is a potential pest management technique for chile pepper in New Mexico.

No-till seeded spinach after winterkilled cover crops in an organic production system

Abstract Organic no-till (NT) management strategies generally employ high-residue cover crops that act as weed-suppressing mulch. In temperate, humid regions such as the mid-Atlantic USA,



Forage Radish Cover Crop Suppresses Winter Annual Weeds in Fall and Before Corn Planting

Forage radish provided complete suppression of winter annual weeds in fall and early spring but the suppression did not persist into the subsequent cropping season, and strategies to use the weed suppression of forage Radish cover crops should focus on fall weed suppression and the early spring preplant window of weed control.

Brassica cover cropping: I. Effects on weed and crop establishment

It is suggested that brassica residues are capable of delaying seedling emergence and reducing establishment, although the magnitude of their effects were comparable to other widely available cover crops.

Ecological weed management by cover cropping: effects on weed growth in autumn and weed establishment in spring

Although a poor competitor in the fall, after incorporation in spring, lucerne had the strongest inhibitory effect on seedling establishment, followed by winter oilseed rape and white lupin, which was strongly correlated to early light interception.

Forage Radish Cover Crops Increase Soil Test Phosphorus Surrounding Radish Taproot Holes

Cover crops can infl uence nutrient cycling in the agroecosystem. Forage radish (FR) (Raphanus sativus L. var. longipinnatus) is unique in terms of P cycling because of its high tissue P

Weed suppression with Brassica green manure crops in green pea

Weed suppression in peas varied between different green manure crops, except for rapeseed, which reduced pea population, and greenhouse experiments, where white mustard added to the soil at 20 g per 400 g air dry soil reduced emergence of shepherd's-purse, kochia, and green foxtail.

Brassica cover cropping for weed management: A review

Unique attributes of brassicas that make them promising options for pest management, as well as generally beneficial cover crops are discussed and some important agronomic considerations about the use of brassica cover crops.

Weed control in soybean (Glycine max) with green manure crops

With the exception of shepherd's-purse, no relationship between glucosinolate content of the incorporated green manure and suppression of weed growth was found, and early spring-planted green manure crops reduced early season weed biomass in soybean at one of the two locations.

Integration of cover crops into no-till and ridge-till wheat (Triticum aestivum L.) – corn (Zea mays L.) cropping sequence

On-farm trials on silt loam no-Till and sandy ridge-till fields in southern Ontario to evaluate the establishment and growth of alternative stubble-seeded cover crops following wheat and their effects on subsequent weed and volunteer wheat growth found oats, oats, oilseed radish, and barley produced more biomass than the other stubbles-seeding cover crops.

Improving Soil Quality: Implications for Weed Management

Many as yet unexplored opportunities exist to manipulate the soil environment and to design cropping systems that create multiple weed suppressive conditions at critical junctures of weed seed-bank persistence, establishment, and interference.

Growth, Nitrogen Accumulation, and Weed Suppression by Fall Cover Crops Following Early Harvest of Vegetables

Oilseed radish, white senf mustard,and yellow mustard are well suited for use as fall cover crops in the temperate northeastern United States, but that significant biomass and N may be lost if they are left to winter kill.
