تأثير سرع مختلفة لنوعين من المحاريث في بعض مؤشرات الأداء للوحدة الميكنية

الملخص EN

This experiment was conducted to evaluate stadying the effect of different speed of two plows types on some machinary unit performance indicators.

New Holland TD80 was used in this study.Three machinery speeds included; 2.72,4.34 and 6.23 km.hr-1 which represent main plot and two plows included; moldboard plow and disk plow which represent sub plot were used in this study.

slippage percentage, practical productivity, Field efficiency, soil volume disturbs and fuel consumption were measured in this experiment Split plot design.The results can be summarized as Fallow; The 6.26 km.hr-1 speed gave higher practical productivity 0.31 ha.hr-1, higher soil volume disturbs 599.07 m3.hr-1,lowest fuel consumption 30.69 L.hr-1 and higher Field efficiency 60.89%.

While speed 2.72 km.hr-1 gave lowest slippage percentage 8.69%.The moldboard plow on the disk plow gave lowest slippage percentage 9.48%, higher practical productivity 0.26 ha.hr-1, higher soil volume disturbs 514.89 m3.hr-1, higher Field efficiency 58.98% and lowest fuel consumption 33.77 L.hr-1.

As for the significant of overlap between the speed 6.23 km.hr-1 and the moldboard plow it has impacted significantly in all traits.
