Management systems influence soil quality over time. A randomized block design in 2 (tillage system) 3 (crop rotation) factorial arrangement was laid-out to evaluate the impact of tillage and crop rotation (2002–2007) on soil quality. Conventional tillage and No-till were factored into continuous corn, corn–soybean, and corn–soybean–wheat–Cowpea systems. Ten soil cores were collected at 0–7.5, ...

Crop cultivars now being grown in no-till production systems were developed by selecting for performance in conventionally tilled environments. In order to maximize production of corn (Zea mays L.), cotton (Gossypium barbadense L.), and soybean [Glycine max (L.) Merr.] in a no-till environment, it may be necessary to select for performance under the same conditions. The economic incentive for d...

introduction: elimination or reduction of tillage in conservation agricultural systems has led to wide variations in germination, emergence, and growth of weeds and has caused variations in the density and diversity of weeds under such systems. maintaining crop residues on the soil surface has many potential benefits in agricultural production systems; such as reducing water and wind erosions, ...

to investigate factors affecting the adoption of conservation tillage systems, the tillage methods utilized by wheat producers in the central darab county are categorized into conventional, reduced-tillage and no tillage systems. for this purpose, multinomial logit model approach using the stata software was applied to the data set collected by random cluster sampling method. the explanatory va...

There is interest in reducing or even eliminating tillage in organic production systems. In this special Issue, research teams in Europe and North America summarize recent and on-going efforts to develop conservation-tillage systems that can be used on commercial organic farms. While progress is being made in the development of organic no-tillage (no-till) systems, considerable work still needs...

high intensity evaporation from the soil surface due to low air humidity and poor soil structure and organic matter are constraints of agriculture in arid and semi-arid regions of iran. regionally, maintaining plant residue with tillage management is one method to improve these conditions. in this study, for a barley-corn rotation, four barley residue management methods for standing stubble (bu...

or no-till. Those who oppose this notion argue that no-till is equated with an abusively high use of herbicides and even genetically modified organisms (GMOs) are synonymous with unsustainable agriculture, with no-till taking all the blame. Unfortunately, both sides are right, and therefore, to get closer to the answer of the initial question, we have to take a deeper look into no-tillage syste...

one of the main strategy for controlling salt-affected soils is to implement proper tillage method. a field experiments was conducted to determine the effect of different tillage methods on salt distribution and wheat yield in saline-sodic soil. the experiment was laid out according to randomized complete block design with three replications. treatments were studied in the experiment including ...

in order to study of no-tillage, reduced tillage and conventional tillage systems on some soil physical properties, yield and some traits of wheat and chickpea, experiments were perfumed across two years in sarpolezahab’s dryland region.results of combined analysis of variance indicated that different tillage systems had significant effects (p≥0.01) on seed yield, volumetric soil moisture, bulk...
