Nitrogen Management and Weed Suppression in Organic Transition
… (Vigna sinensis Endl.) to supply N and suppress weeds and, 3) to compare the effect on N availability and broccoli yield potential of incorporating cover crops with conventional tillage (CT) or mulching cover crops with no-tillage (NT) practices. Broccoli was grown during the third year of …

Interactions between cover crop residue and microbial community affect weed suppression
… developing alternative methods for agricultural weed control. Incorporation of cover crop residues is an important approach that contributes to alternative weed management systems. The cover crop residue-associated allelochemicals can inhibit weed germination, growth and production. Soil …

Influence of Cover Crop Termination Timing on its Volunteers and Weed Suppression
… termination can lead to cover crops becoming weeds in the subsequent cash crop, known as volunteers. Studies were conducted from 2020-2022 to evaluate the effect of four commonly grown cover crop species, winter wheat (Triticum aestivum L.), cereal rye (Secale cereal L.), hairy vetch (Vicia …

Optimizing Weed Suppression Via Cover Crop and Herbicide Programs in the Mid-Atlantic
… crop management for specific goals, such as weed suppression and nitrogen fertilizer reductions. Waiting to terminate the cover crop until cash crop planting, so-called "planting green," is often part of the management and is an evolution from the traditional termination timing prior to cash …

Effects of overseeded legume living mulches and tillage on weed suppression and broccoli yield
… vetch, Vicia villosa Roth.) at transplanting on weed suppression and yield of ’Big Sur’ broccoli (Brassica oleracea var. italica Plenck). In both sites, weed suppression from overseeded red clover, white clover, and hairy vetch equalled or surpassed that of the preemergent herbicide (oxyfluorfen) …

Impacts of Spring-interseeded Cover Crops on Late-emerging Weed Suppression and Ground Cover in Corn (Zea mays L.) Production Systems
… or provides other beneficial features such as weed control or suppression. Corn production that incorporates a cover crop as an alternative weed control strategy and ground cover may support a sustainable system that is less dependent on herbicidal weed control. In addition, the cover crop may …

High Residue Cover Crops for Annual Weed Suppression in Corn and Soybean Production and Potential for Hairy Vetch (Vicia villosa) to be Weedy
… termination, cover crop residue can suppress weeds by reducing sunlight, decreasing soil temperature, and providing a physical barrier. Experiments were implemented to monitor horseweed suppression from different cover crops as well as two fall-applied residual herbicide treatments. Results …

Cover crop management strategies for driver weeds in Kansas
… region to understand how cover crops influence weed suppression and seedbanks. As cover crops increase on farm production hectares, management strategies must be evaluated to discover which ones result in optimum weed control. The effects of cereal rye cover crop on Palmer amaranth (Amaranthus …

Cover crop programs, termination methods and timings, and suppression mechanisms on weed growth and competition
… of pesticides are all challenges for managing weeds in production agriculture. The use of cover crops (CC) has emerged as a promising integrated weed management tool to aid in weed suppression. There are many questions concerning the best management practices to reap the most benefits from CC. …

Value of Cover Crops in Suppressing Weeds and Protecting Cotton Yields and Likelihood of Residual Herbicide Carryover to Cover Crops
<p>Weed-resistance management has become a topic of concern for modern agriculture. Cost related to herbicide usage has increased greatly due to evolution and proliferation of resistant weeds. Therefore, experiments were conducted to investigate the potential for using cover crops to suppress …

No-Till Vegetable Production at the Cal Poly Organic Farm
… mulch on the soil surface. There were less weeds in NT plots. A corollary experiment was conducted in 2007-2008 to help determine the best cover crops for a no-till system. There was no difference in the amount of biomass produced by the different cover crops, although anthesis for ‘Juan’ …

Plant Residues and Newspaper Mulch Effects on Weed Emergence And Collard Performance
… products. As with most agriculture production, weed suppression is a major concern for urban growers. Mulch is ideal for managing weeds because it is inexpensive and readily available. A variety of mulches have been found successful in conserving soil moisture, moderating soil temperature, …

Vegetation management effects on fruit trees
… the fruit tree nutritional status, and weed suppression through possible allelopathic affects are also taken into account. Eleven preemergence herbicide treatments were applied at two commercial orchards, located in Hoges Chapel, Virginia and Daleville Virginia to evaluate the influence …

Do benefits from cover crops vary by species or mixture composition?
"Cover crops are often used to manage weeds and increase productivity on organic farms, but questions remain about which species or combinations of species have the strongest impacts as living cover and which species and combinations are financially feasible for adoption in organic systems. An …

Soil quality in organic cropping systems
… studies examining crop yield, soil quality and weed control were conducted in Boone County, MO on a Mexico silt loam soil (fine, smectitic, mesic Vertic Epiaqualfs) from 2012-2014. Achieving a cover crop biomass sufficient for weed suppression was a challenge when soil fertility declined under …

Utilization of common buckwheat as a short-cycle cover crop before direct-seeded processing cucumber production
Weeds are difficult to control in processing cucumber (Cucumis sativus) production because of the growth habit of cucumber and its sensitivity to herbicides. One alternative method is utilizing short-cycle summer cover crops, such as common buckwheat (Fagopyrum esculentum) prior to planting …
