The primary goal of Serious Games is not only for fun but also lesson. In learning the first stage soil tillage which using mouldboard plow, a proper understanding needed so that process will follow needs plant growth. use serious games as study instrument under concept digital game-based (DGBL). problem players when playing less motivated to play because game system and scenario are challengin...

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 ...

using the cropping operations program can significantly save fuel consumption and energy efficiency. prediction of the accurate amount of fuel requirements for tillage operation of the soil is difficult. changes in humidity, soil type and tillage depth directly affects on the amount of fuel consumption. bulk density of agricultural soils depends on tillage methods, the value of organic matter, ...

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 ...

The effects of three levels of soil moisture content (8-10, 10-12 and 12-14% d.b.) and three levels of plowing depth (15, 20 and 25 cm) on draft, specific draft and drawbar power requirement of a 7-shank chisel plow in a clay loam soil were investigated. The experimental design was a randomized complete block design with a 3×4 factorial. The effect of plowing depth on all of the parameters ment...

In cold climates, snowmelt runoff often exceeds rainfall runoff during the year. Conservation tillage practices may be effective in reducing runoff during the cropping season but not during the snowmelt period. A plot study was conducted on a cropped hillslope to assess how tillage practices affect snowmelt runoff and the associated losses of sediment, phosphorus (P), and chemical oxygen demand...

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 use of sprinkler irrigation for rice (Oryza sativa L.) crop is a relatively recent practice in Brazil. Therefore, crop soil and fertilization management are still not very well defined. Another problem is the inexistence of specific cultivars adapted to this cropping system. This study aimed to evaluate sprinklerirrigated upland rice cultivars under different soil management practices and n...

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...
