Synergistic Effects of Monoculture Biofilm Dispersion and Antibiotic Treatment
Bacterial biofilms have been identified as the causative agent of many infections, including catheter associated urinary tract infections (CAUTIs). While in a biofilm state, bacterial cells are less susceptible to antibiotic therapy. However, once released from a biofilm, antimicrobial …

Influence of vegetation on sediment bacterial community structure, microbial enzyme activities and phosphorus retention in constructed freshwater wetlands
… or Dichanthelium acuminatum var. acuminatum in monoculture or mixed culture. </p> <p>To study the influence of vegetation on the bacterial community structure and microbial enzyme activities, sediment samples were taken from monoculture mesocosms in the greenhouse. β-1,4-glucosidase, …

Establishment, Forage Production and Drought Resistance of Native Perennial Legumes of the Canadian Prairies
… and early vs. late season forage production in monoculture, and in mixtures with Bromus riparius, in the Brown and Dark Brown soil zones of the Canadian Prairies near Swift Current and Saskatoon, SK. The experimental design was a Randomized Complete Block Design with four replicates with …

Evaluation of Yield and Agronomic Performance of Leafed and Semi-leafless Pea Blends
… leafed pea yield loss compared to the leafed monoculture; however, the blend did not affect light interception, disease, lodging, and yield relative to the semi-leafless monoculture. The estimated optimal blending ratio, 86:14% SL/L, had a 13% yield increase compared to the leafed monoculture, …

Conservation agriculture in Senegal: comparing the effects of intercropping and mulching on millet yields
… one variety of mungbean (upright) were grown in monoculture and subsequently intercropped with millet to evaluate the potential for increasing millet and overall yields. Millet was also planted with a mulch (2 t/ha of neem leaves) to test the effectiveness of increased ground cover on millet …

Elucidating the ecophysiological complexities of maize and soybean intercrop systems to improve ecosystem services
… yield stability in plant mixtures relative to monocultures, particularly by cereal-legume intercrops. The mechanisms behind such advantages have been attributed to the relaxation of competition due to niche complementarity, facilitation, and/or selection. Realising these ecological principles …

Do benefits from cover crops vary by species or mixture composition?
… species per season) and planted in all possible monocultures and five-way mixtures with a weedy and weeded control on two organic farms in central and northern Illinois. Results suggest that cover crop species and mixtures had different capacities for producing biomass and competing with weeds, …

Impact of nutrient heterogeneity on plant response and competition in Coastal plain species
… for six species native to southeastern USA. Monoculture, two- and six-species garden plots were established and fertilized to create spatially homogeneous or heterogeneous nutrient conditions. After 3.5 months, root proliferation in rich patches (precision) and aboveground biomass response to …

Exploring and Re-envisioning the Significance of Agrarian Consciousness in Theology with Specific Reference to Kerala
… It is an attempt to delink the principles of monoculture and commercialized consciousness of Kerala society and to relink to the agrarian consciousness where they understand life in its particularity and fullness. The globalized monoculture commodifies human beings and places whereas the …

Diversifying crop systems by developing intercropping breeding strategies for improving forage yield and quality in oat-legume mixtures
… and ecological factors that have entrenched monoculture in the Midwest, highlighting the resulting vulnerabilities to climate variability, soil degradation, and input dependence. We build a case for spatial re-diversification through intercropping to enhance agroecosystem resilience and …

Intercropping dynamics in a perennial Kernza cropping system
… intercropped with the perennial forage alfalfa. Monoculture Kernza was grown in both unfertilized and fertilized settings. Alfalfa was also grown in a monoculture. Each of these treatments was replicated four times. Data was taken on both Kernza plant development and the harvestable productivity …

Greenhouse gas fluxes and root productivity in a switchgrass and loblolly pine intercropping system for bioenergy production
… from January 2012 to March 2013 in four-year-old monoculture and intercropped stands of loblolly pine and switchgrass. RS is primarily the result of root respiration (RA) and microbial decomposition of organic matter (RH) releasing CO₂ as a by-product and is an important and large part of the …

Cover Crop Systems Impact on Biomass Production, Carbon-to-Nitrogen Ratio, Forage Quality, and Soil Health Indices in a Semiarid Environment.
… biomass and diversity compared to cover crop monocultures. Consequently, the objectives of this 2-yr study were to (i) quantify the above- and belowground biomass production, forage nutritive value, and tissue carbon and nitrogen concentrations from different annual cool-season cover crop …

Intercropping with resistant cultivars reduces early blight and root knot disease on susceptible cultivars of tomato (Lycopersicon esculentum)
… resistant cv. 'Juliet' than with 'Brandywine' monoculture in both the field and greenhouse. Yield from 'Brandywine' plants was 17.3% greater when intercropped with 'Juliet' than when grown in monoculture. Reduction in lesion expansion on 'Brandywine' when intercropped with 'Juliet' suggests an …

Connecting the dots: Remote sensing of Glossy and Common Buckthorn (Frangula alnus and Rhamnus cathartica) in the Oak Openings Region of Northwest Ohio
… are invasive woody shrubs that formed dense monoculture thickets in the Oak Openings Region of NW Ohio. Conventional techniques of vegetation mapping are expensive and time-consuming. Thickets were identified using remotely sensed land surface phenology of buckthorn, that leafs out earlier …

The effect of a cabbage-carrot intercropping system on the incidence of cabbage pests
… trials had five treatments viz. control (cabbage monoculture sprayed with mercaptothion), cabbage monoculture (without chemical application), 1:1 intercropping (cabbage:carrots), 1:3 intercropping and 1:5 intercropping, replicated six times in a randomized block design. Insects were sampled weekly …

Nitrogen fertilization, yield components, and species selection of perennial grass bioenergy cropping systems across eastern North America
… a high-diversity recreated tallgrass prairie. Monoculture stands of Miscanthus and switchgrass produced more biomass than the prairie system while the stands were young, but yields of monoculture crops declined with stand age. The monoculture stands produced more biomass than the prairie stand …

Optimizing Weed Suppression Via Cover Crop and Herbicide Programs in the Mid-Atlantic
… in March, performed better than a hairy vetch monoculture for biomass accumulation and weed suppression. Results indicated that hairy vetch monocultures typically produced greater hairy vetch biomass throughout the season, had greater nitrogen contents, and provided similar weed suppression. …

VERS UNE ECOCRITIQUE POSTCOLONIALE AFRICAINE: L’ENVIRONNEMENT DANS LES LITTERATURES AFRICAINES DE LANGUE FRANÇAISE
… work also draws on Vandana Shiva's concept of 'monoculture of the mind' to study the colonial project of monoculture as a corollary of the policy of standardization, also known as assimilation. Even though some concepts are borrowed from Western ecocriticism, new notions are defined and …
