The paper proposes a new method for multistage plowing that implies loosening bottom soil and subsoil horizon simultaneously, followed by overturning the without cutting, which improves quality of cultivation, softens plow sole reduces energy costs. Experimental studies confirmed theoretical relationship determining resistance, both certain working bodies section, whole plow. proposed provides ...

The no-tillage system is perceived as having lower soil temperatures, wetter soil conditions, and greater surface penetration resistance compared with conventional and other conservation tillage systems. Concerns associated with the effect of the no-tillage system on certain soil physical properties (i.e. soil temperature, moisture, and compaction) prompted this study to evaluate the effect of ...

Producers are frequently most interested in economic comparisons of various cropping systems. We compared continuous corn (Zea mays L.) and continuous soybean [Glycine max (L.) Merr.] with 2-, 3-, and 5-year rotations, the latter two including wheat (Triticum aestivum L.) and alfalfa (Medicago sativa L.), using either chisel plow or no-tillage practices. Crop yield and returns to land and manag...

The purpose is to investigate substantiate relative position working bodies of improved plow-ripper. Scheme the plow-ripper given. consists left and right sections, a ripping share established down axle symmetry tool, with inclined racks. Analytics dependencies are mined define distance between organs them along Experiments have been carried out come true relation stance bodywork. that an incre...

Energy consumption in Iran is a subject of debate. Some may think that oil is cheap in Iran and thus no need for this kind of research. This simple minding is erroneous first because Iran subsidizes billion dollars each year for the imported diesel fuel specially for agricultural use and second because energy studies reveal the degree of professionally using the technology. We can easily find t...

This work aims to substantiate the effectiveness of use an active working body on a front plow. The necessity using bodies is justified, and plow with passive proposed. efficiency installing analyzed. forces acting combined frontal are considered. analysis influence stability movement traction resistance carried out. results experimental studies presented. increases degree soil crumbling by 8,5...

The article is devoted to determining the effect of mineral and microbiological fertilizers on grain yield spring durum wheat (variety Luch 25) cellulose-decomposing ability soil during moldboard minimal tillage. It concluded that provide maximum efficiency, which in turn contributes an increase crop yields.

An improved whole cell pertussis vaccine, designated as Plow, which is low in endotoxicity due to a chemical extraction of lipo-oligosaccharide (LOS) from the outer membrane, was evaluated for safety, immunogenicity and potency, comparatively to a traditional whole cell pertussis vaccine. Current whole cell pertussis vaccines are effective but contain large quantities of endotoxin and consequen...

Prefix 10.18034 This performance evaluation was conducted to pave the way for making use of Draught Animal Power Cultivator and cosequently possibilities of adaptation in our local condition between 2010 and 2011 in the Jimma zone two districts of southwestern Ethiopia on the farmers’ field to evaluate energy requirement. To improve weed management at the small holder farmers level, animal-draw...

Dryland farming in the Mediterranean climate of the Pacific Northwest, USA supports extremely low earthworm populations under conventional tillage. Increases in earthworm populations are being observed in fields under no-till cropping systems. A 30+ year experiment with four tillage levels in a pea (Pisum sativum L.)-winter wheat (Triticum aestivum L.) rotation was evaluated for earthworm popul...
