this study was carried out to evaluate the effects of tillage practices (with different depths) on soil penetration resistance, technical parameters and grain yield of wheat crop. the experiment was conducted as a randomized complete block design with three replications for two years. treatments included: moldboard plow fallowed by two passes of disc harrow and leveler (ct), two passes of disc ...

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...

This research delves into investigating the effects of different soil management practices on soil physical properties, yield and yield’s components of irrigated wheat. This experimental design was administered in the form of the nested testing with three treatments (no tillage, low tillage and conventional tillage) and three replicates in some of the farmlands of Chenran Township. The results ...

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...

could be optimized using modified NT systems (including ST) and starter fertilizer. In Iowa Mallarino et al. (1999) Utilizing conservation tillage practices and increasing fertilizer N found that ST frequently increased early growth but seluse efficiency for corn (Zea mays L.) are necessary for optimizing dom increased corn grain yields compared with NT. growers’ profits and for minimizing loss...

applying a suitable tillage method is vital to chickpea production in dryland conditions. hence, eight tillage methods were studied using strip plots in a randomized complete block design with three replications over three years at the dryland agricultural research institute in maragheh, iran. the amount of rainfall in the three years of the study were 202, 264 and 203 mm, respectively, which w...

in order to determine the effect of different tillage methods on grain yield and yield components of two wheat cultivars an experiment was conducted in sanandaj in during 2005 and 2006-2007. experiment was carried out in a split plot design based on rcbd with four replications. the three methods of tillage, including moldboard plow, chisel plow and no tillage were arranged as main plots, and tw...

Conventional tillage winter wheat (Triticum aestivum) (WW)–summer fallow reduces soil productivity and increases soil erosion. Conservation tillage management, together with intensive cropping may have the potential to reverse these sustainability concerns. The objective of this study was to determine the effects of conventional tillage (CT) and no-tillage (NT) systems on grain yield of long-te...
