| Abstract | ||
| ABSTRACT: The experiment was conducted to study effect (tractor + Chisel and Rotary plow) under two cultural distance (20 and 40) cm and three tractor speed (3.080 ,4.561 , 5.511 )kmhr in some performance parameters , soil physical properties and corn yield . slippage percentage , fuel consumption , field efficiency, soil bulk density, soil penetration resistance, dry weight of root and corn yield The result showed that the chisel plow was significantly superior to the rotary plow in all studied properties. The result showed that the cultural distance 20cm was significantly superior to the cultural distance 40cm in slippage percentage, fuel consumption , and cultural distance 40cm was significantly superior to the cultural distance 20cm in field efficiency ,soil bulk density, soil penetration resistance and all yield properties .increase in tractor speeds from (3.080 to 4.561 and 5.511 )kmhr caused an increase in slippage percentage, soil bulk density, soil penetration resistance ,And decrease fuel consumption , field efficiency and all yield properties . | ||
