Fall and spring broccoli yields and weed control under no-till and conventional tillage with overseeded legume living mulches
… Virginia. Objectives were to determine the tillage main-plot (CT = conventional tillage, and NT = no-tillage) and weed-control subplot (C = no overseeding or preemergent herbicide; HB = oxyfluorfen; RC = red clover (<i>Trifolium pratense</i> L.); WC = Dutch white clover (<i>Trifolium …

A comparison of the performance of Namibia-specific conservation and conventional tillage technologies as used for pearl millet production in northern Namibia
… tractors and animal-drawn implements both using conventional and Namibia Specific Conservation Tillage (NSCT) technologies. Two conventional tillage (CV) treatments (i.e. tractor-drawn disc harrow (TDH) and animal-drawn mouldboard plough (AMP) were compared to two NSCT treatments (tractor-drawn …

Yield response of continuous corn to residue removal, tillage, and nitrogen rate
… for use as biofuel may require adjustments in tillage systems and nitrogen rates. Research was conducted at DeKalb, Monmouth, Urbana, and Perry, Illinois to examine the response of three residue removal rates (full, partial, and none) and two tillage treatments (no-till and conventional …

Evaluating Conservation Agricultural Management for Soil Health Outcomes in Southeastern Virginia
… such as cover cropping and conservation tillage systems (e.g., strip tillage, minimal tillage, or no tillage) are implemented to improve soil properties, but soil health outcomes in Coastal Plain cropping systems have been inconsistent and may take decades or longer to occur. Improving …

Long-term effect of crop rotation and tillage on soil properties
… forages to mostly annual crops has intensified tillage, and led to the development of conservation tillage practices such as no-till. There is a shortage of information about the interactive effects of rotation and tillage on soil productivity, and consequently, the long-term effect of these …

Effects of tillage and mulching on selected soil properties, growth and yield of sunflower (Helianthus annuus L.)
Excessive and unnecessary tillage without residue retention can degrade the soil’s physical quality, decrease soil organic carbon contents and crop yields. Although the benefits of improved tillage methods and mulching have been reported in literature, little information is available on South …

Strip-Tillage Production Systems for Tobacco
Conservation tillage production systems for flue-cured tobacco (Nicotiana tabacum L.) have been studied for many years. Inadequate chemical weed control and lack of acceptable pesticide and fertilizer application resulted in consistently lower yields and inferior cured leaf quality. The development …

Effect of winter cover cropping practices on maize yield and nutrient cycling
… annual rye winter cover-cropped treatment to a conventional tillage control (fall chisel and spring field cultivation) by measuring preseason fertility, nutrient flux in subsurface tile lines, end of season soil fertility, and crop yields for each treatment. Best management practices consisted …

Using Winter Annual Cover Crops in a Virginia No-till Cotton Production System
… crop treatments were monitored under no-till and conventional tillage systems for the effects on soil moisture, cotton yield and quality. Six cover crop treatments, crimson clover (<i>Trifolium incarnatum</i> L.), hairy vetch (<i>Vicia vilosa</i> L.), hairy vetch and rye (<i>Secale cereale</i> …

Strip-till flue-cured tobacco production in Virginia
… that typically receives four to eight primary tillage passes before being transplanted on a raised row-ridge. Strip-tillage, a conservation tillage system that only requires tilling a small strip before transplanting, has been shown to be effective for tobacco producers in southside Virginia. …

Leaching and denitrification losses of nitrogen from corn fields as influenced by conventional- and no-till practices in soils of the Chesapeake Bay area
… primarily to determine the combined effects of tillage practice and N fertilizer application rates on N leaching and denitrification losses from corn fields. Three well known models - the NTRM, CERES- Maize, and VT-MAIZE - were also tested to determine their predictive ability of N distribution …

A computer simulation model for predicting pesticide losses from agricultural lands
… simulated rainfall. The plots were treated with conventional or no-tillage in combination with one of three residue levels (0, 750, and 1500 kg/ha). Runoff and sediment losses were found to increase with decreasing residue cover for both tillage systems. No-till reduced sediment loss and total …

Surface and groundwater quality impacts of conservation tillage practices on burley tobacco production systems in Southwest Virginia
… edge-of-field and deep percolation losses from conventional tillage (CT), strip tillage (ST), and no-till (NT) treatments in a burley tobacco production system. The field experiment results show that the CT treatment yielded more total runoff, 93.6 mm, than ST and NT. Compared to the CT …

Influence of Transplanter Modification and Previous Crop on the Production of No-Till Dark Tobacco
… L.) has historically been produced using<br />conventional tillage practices. Soil is cultivated multiple times throughout a growing season leading to an increased incidence of soil erosion. No-till systems have been growing in popularity with the advent of new technology that has enabled the …

Analysis of the Effect of Two Tillage Systems on Soybean (Glycine Max (L.) Merrill) Growth
… soybean yield is not substantially affected by tillage. Available reports of differences are in the minority. There is relatively little information as to what extent and under what conditions the tillage methods affect the growth of soybean in the central Corn Belt. This is of particular …

Probabilistic approach to modeling under changing scenarios
… and two alternative land management scenarios (conventional tillage for grain, and conventional tillage for graze out) were proposed and simulated over the study area to observe their effects on the monthly N loads. Results suggested that changes in land use and land management did not affect …

Zero tillage for cereal production on forage sods in Manitoba
The effects of zero, minimum and conventional tillage on soil water content, soil compaction and crop growth on a fine-textured soil previously sown to perennial forages was studied over a two year period. The effect of glyphosate, 2,4-D and dicamba, alone or in combination was evaluated for the …

The use of legume cover crops in no-tillage broccoli and cabbage production
… were conducted in 1983 and 1984 to compare conventional tillage (CT) versus no-tillage (NT) production of broccoli and cabbage. The tillage treatments were applied in combination with four rates of applied nitrogen fertilizer and three cover crops: hairy vetch (<u>Vigia villosa</u> Roth), …

Herbicide phytotoxicity response and eradication studies in Miscanthus x giganteus
… The second experiment demonstrated that both tillage and a single glyphosate application significantly reduced above-ground dry biomass, and that tillage in combination with one or two glyphosate applications provided the highest level of control in the same growing season. These experiments …
