Irrigation management effects on nitrate leaching and mowing requirements of tall fescue
… fescue (Festuca arundinacea) and also affect its mowing requirements. Two experiments were conducted on tall fescue growing on a Chase silt loam soil near Manhattan, Kansas. Each experiment was arranged in a split-plot design, with irrigation treatments applied to whole plots: 1) frequency-based …

The Investigation of the Soil Seedbank in a Long-term Mowing and Fertilization Experiment
… how fertilization, drainage, and disturbance (mowing) have affected the seedbank community in a long-term experimental study of a coastal plain wetland. After 20 years of mowing, unmowed plots are dominated by trees with a limited understory, while the mowed plots are dominated by herbaceous …

Functional diversity and mowing regime of flower strips as tools to support pollinators and to suppress weeds
… competition and adapting timing and frequency of mowing can be used as tools to limit weeds in flower strips, and (3) whether flower strips perform equally in supporting pollinators as the natural habitat for which they are thought to be a surrogate. To use functional diversity as a tool to …

Between-row mower design for weed control in organically grown no-till soybeans
… weed density and improve organic yield. In 2017, mowing between crop rows was compared to cultivation in two central Missouri locations (Herman and Bradford Research Center). Cereal rye (Secale cereale L.) was used as a cover crop in some mowing treatments. Treatments included 1) pre-plant tillage …

Influence of cover crop management on Armyworm, Pseudaletia Unipuncta (Haworth) seasonal abundance, natural enemies, and yield in no-till corn, and diurnal abundance and spatial distribution of Armyworm
… a winter cover crop was killed by paraquat or by mowing with a bushog. In subsequent no-till corn, early season armyworm, <i>Pseudaletia unipuncta</i> (Lepidoptera: Noctuidae) abundance was lower in the mowed treatment compared with the sprayed treatment. Total cumulative armyworm-days in the …

Canopy, microenvironment, and nitrogen effects on summer recovery of tall fescue
… and regrowth of tall fescue in response to mowing managements and nitrogen rates in spring that created different canopy structures was studied. In early spring, 50 and 160 kg/ha of N were applied. Mowing managements were: clipping at 4 or 8 cm biweekly, monthly, and in late June. In late …
