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 …

Response of Soil Properties to 23-25 Years of Diverse Crop Rotations and Tillage Systems in South Dakota, USA
<p>Diverse cropping systems and no-till (NT) are beneficial in improving soil organic carbon (SOC) and other soils properties. The present study was conducted to evaluate the interactions and impacts of long-term tillage and diverse crop rotation systems on soil quality indicators that include a …

The effects of selected corn-soybean tillage systems on rill cross-sectional geometry and soil erosion for two Illinois soils
… rill cross sectional geometry under different tillage, crop and soil conditions and to relate variations in rill geometric properties to measured sediment discharge and to soil erosion and sediment transport predicted by various models. In the experimental phase of this study, simulated …

To Till or Not to Till: The Question of Economic Efficiency and Tillage Systems in a Sample of Illinois Grain Farms
… to segment the farmer's market with respect to tillage practice, might benefit from the analysis done concerning reaction to price changes. The knowledge that efficiency regime does not change with tillage practice is important for policy makers, who constantly have to assess the potential …

Conservation tillage methods for cabbage production
… were to assess the applicability of conservation tillage systems for cabbage production. Four tillage systems (conventional tillage, CT; no-tillage, NT; and two types of strip tillage—Ro-till, RT, and chisel plow, CP) and three planting dates (early, mid and late) were compared in 1985 and 1986. …

The influence of application timing and soybean (Glycine max L.) canopy on imazethapyr efficacy
… row spacings and reduced herbicide rates in no-tillage systems shows promise (DeFelice et al., 1989). However, the issues of the appropriate herbicides to use, proper application timings, and the size of the weeds at the times of application become important factors to address. These concerns …

Tillage System Effects On Upland Cotton Yield and Development In Virginia
Identifying the proper tillage system which provides the best agronomic benefits for cotton production in the coastal plain soils of Virginia was the basis for this research. Strip-tillage was evaluated from 2015-2016 on-farm to determine the effects of annual and biennial treatments on plant …

Effect of tillage system and nitrogen rate on tomato yield
Experiments to evaluate the effects of tillage systems and nitrogen fertilizer rates on fresh market 'Pik Red' tomato (Lycopersicon esculentum Mill.) production were carried out at Blacksburg, Virginia (1981 and 1982) and at Carrasco and Jackson, Uruguay (1981-2). Two tillage systems were used: (a) …

Tillage effects on soil physical properties, weed seed distribution in soil and shifts in species
A tillage experiment established in the fall of 1986 in a Thorp silt loam was used to conduct a study on how long-term tillage systems affect soil strength, bulk density, soil water characteristics, weed seed distribution in soil, and shifts in species. The experiment included a corn-soybean …

No-tillage squash production on agricultural soil and minesoil
No-tillage establishment into a killed surface mulch on agricultural soil increased marketable acorn squash (Curcurbita pepo L. 'Table Ace’) yield by 29% as compared to a conventional tillage practice. These yield differences are attributed to increased plant population and possible improved water …

Empirical Studies in Production Economics and International Agricultural Development Issues
… titled "Profitability Effects of Different Tillage Systems in Continuous Corn Rotations" explores the interaction between different tillage systems and nitrogen fertilization in irrigated continuous corn production in northeastern Colorado. We find that strip tillage is better suited for …

Surface conditions effect on energy exchange at the soil surface
… at or near the soil surface. Study one examined tillage effects on soil thermal properties and heat flux. Study two examined surface roughness effects on soil reflectance, net radiation, and the partitioning of net radiation;Soil thermal properties were examined after planting in the row zone for …

Using Winter Annual Cover Crops in a Virginia No-till Cotton Production System
… 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> L.), rye, wheat …

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 …

Stover, tillage, and nitrogen management in continuous corn for grain, ethanol, and soil carbon
… heavy-textured, poorly-drained soils in several tillage systems in environments where soil temperature is often a limiting factor on crop growth. This research indicates corn stover removal in continuous corn cropping (CC) systems improves agronomic performance, but decreases soil C in as little …

Tillage effects on properties of Grantsburg soil and growth of corn (Zea mays L.)
A three-year tillage project, involving three treatments of no-tillage (NT), chisel-plow (CP), and moldboard plow (MP), was conducted in Southern Illinois. The objectives of the study were to: (1) determine effects of tillage on properties of a sloping and eroded Grantsburg soil (fine-silty, mixed, …
