Recent developments in biofuel demand and the rapid adoption of modern transgenic hybrids are changing production systems towards more corn after corn, more intensive tillage, higher plant populations, and ever higher crop residue levels at harvest. Meeting society’s needs for food, feed, and fuel from grain corn, and in the future from corn stover, requires continued refinement of tillage syst...
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...
Limited time for crop residue decomposition and complete seedbed preparation in double-cropping necessitates reduced tillage which is associated with its shortcomings. Information about seedbed preparation aspects in double-cropping of wheat and mungbean in Isfahan is lacking. For this reason, the effects of various seedbed preparation methods on growth, seed yield and yield components of mungb...
magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
gregate formation (Horn, 1990; Zhang, 1994). Understanding of mechanical properties of aggregates is cruAggregate properties determine the macroscale structural condicial to explain the macroscale functions of soil for plant tion of the soil. Understanding of impacts of no-till and traditional growth (DeFreitas et al., 1996). agricultural practices on the mechanical properties of aggregates is ...
The field experimental was conducted (2020-2021) at Trppaspyan village and Research center of Agriculture Ainkawa to evaluate the influence different tillage systems with two cultivars in locations on growth yield maize. design includes eight treatments three replication laid out a Randomized Complete Block Design factorial. include: chisel plow (T1), moldboard (T2), harrow disc (T3), zero (T4)...

The increased potential for soil erosion and compaction due to continuous row crop production and intensive tillage is causing some concern and has led to the consideration of reduced tillage techniques as part of the solution. The objective of this study was to investigate the short-term (one-year) influences of different management practices on the physical properties of a sandy loam soil und...
Increased yields with conservation tillage have been attributed to the conservation of soil water (Rao and Sustainable cropping systems are essential for agronomic, ecoDao, 1996; Papendick and Miller, 1977) due to decreased nomic, and environmental reasons. Data from a winter wheat (Tritievaporation and cooler soil temperatures (Gauer et al., cum aestivum L.)/summer fallow rotation experiment, ...
The famous empirical model for the horizontal force estimation of farm implements was issued by American Society Agricultural Biological Engineers (ASABE). It relies on information soil texture through its adjustment parameter, which is called Fi -parameter. Fi-parameter not measurable, and geometry plow machine parameter values are measurable; however, tillage speed, implement width, depth mea...
