دراسة تأثير أعماق حراثة و سرع مختلفة في بعض مؤشرات الأداء للوحدة الميكنية

الملخص EN

Research has included to study the effects of plowing deapths and different speeds on some performance indicators of the machine unit under two levels of deep tillage (15-20 ) cm and ( 25-30 ) cm and three levels of practical speed of the machine unit ( 2.8, 4.47 and 6.32 ) km / h with three replications.

LSD test under 0.05 levels was used to compare the treatment means.

The studied parameters were: Slippage percentage, coefficient of speed exploitation, effect field capacity, Field efficiency, soil volume disturbs and fuel consumption per area.

The results showed: that the depth 11 – 10 cm is superior in different effects to the depth 2-00 cm on all study parameters except soil volume distribution 419.2 m3 / h .

and also the results showed that the speed 6.32 Km/h is superior in different effects to the other speed on all study parameters except slippage percentage 13.86 %.

Mean while the interaction between the first depth 11-10 cm with the third speed 6.32 Km / h are superior in different effect to the all treatment recorded the highest value of the effected field capacity 0.302 ha / h by the less value of the fuel consumption 19.65 L / ha.
