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...

This paper reviews research performed at the Justus-Liebig-University of Giessen, Germany into the impact of different tillage systems on soil properties and quality. The impact of intensive soil tillage treatments on several soil properties was described by means of selected data obtained through long-term interdisciplinary research. The experiments were based on comparative application (long-...

Concerns about rising greenhouse gas (GHG) concentrations have spurred the promotion of no-tillage practices as a means to stimulate carbon storage and reduce CO2 emissions in agro-ecosystems. Recent research has ignited debate about the effect of earthworms on the GHG balance of soil. It is unclear how earthworms interact with soil management practices, making long-term predictions on their ef...

Effects of tillage and crop rotation o n nematode densities in tropical corn (Zea mays L. Pioneer Brand X304C) were determined in each of three seasons (1990-1992) in north Florida. Treatments in the factorial experiment consisted of conventional or n o tillage and rotation with sorghum (Sorghum bicolor [L.] Moench) or soybean (G/ycine max [L.] Merr.). Tillage and rotation treatments were maint...

No-tillage cultivation offers significant advantages over con­ ventional tillage in terms of water, energy, and particularly soil conservation (Francis et al., 1987). However, continuous no-tillage farming on sandy Ultisols may lead to high bulk density that has a pronounced effect on soil strength due to traffic compaction and lack of plowing (NeSmith et al., 1987). This increase in soil stren...

An experiment with five different tillage systems and their influence on fuel consumption, labour requirement and yield of tested crops was carried out on Albic Luvisol in northwest Slavonia in the period of 1996.-2000. The compared tillage systems were: 1. conventional tillage system (CT), 2. reduced tillage system (RT), 3. conservation tillage system I (CP), 4. conservation tillage system II ...

the erosion in dryland caused decrease in yield and soil quality, especially in slope land with conventional tillage. to investigate effect of tillage and planting methods in slope land on erosion and yield of dryland wheat, an experiment was conducted in 2007 at kermanshah province. the statistical design for this research was strip split plots in rcb (randomized complete blocks) with three re...
