A major challenge for agriculture is to enhance productivity with minimum impact on the environment. Several studies indicate that cover crops could replace anthropogenic inputs and enhance crop productivity. However, so far, it is unclear if cover crop effects vary between different cropping systems, and direct comparisons among major arable production systems are rare. Here we compared the sh...

dryland winter wheat (triticum sativum l.) generally grown in rotation with fallow or chickpea (cicer arietinum l.) constitutes a major crop in the west region of iran. information is limited on the success of more intensive dryland cropping systems while applying conservation tillage management. an experiment was conducted to determine the effect of five tillage systems on soil physical proper...

Despite the importance of sesame (Sesamum indicum L.) in the world, this crop has received least research attention in Pakistan. Therefore, a field experiment was carried out to evaluate the performance of tillage system under various irrigation intervals and phosphorus levels on oil contents, yield and yield attributes of Sesame. The experiment was conducted at New Developmental Farm of the Un...

Physical, chemical and biological attributes of soil surface are significantly affected by tillage practices and crop rotation. The objective of this study was to determine the short-term (2006-2009) effects of conventional and conservational tillage practices on selected soil physical properties of a heavy clay soil under two wheat-corn and wheatlegume rotation in a semi-arid Mediterranean...

Effects of six tillage practices on some soil microbiological properties and crop yields were evaluated for a clay soil (Typic Haploxererts) under semi-arid Mediterranean conditions in a three year study (2006-2009). The experiment was designed as a completely randomized-block with three replications. Treatments were: conventional tillage with residue incorporated (CT1), conventional tillage wi...

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...

abstract in order to assess the environmental impact of agricultural activity, the long-term sustainability should be considered. in order to achieve solutions to reduce energy consumption and carbon emissions in the production of rainfed sunflower, this assessment was conducted in the north east of iran. four production methods, i.e. conventional tillage (ct), tow reduced tillages (rt1and rt2)...
