| Abstract | ||
| This study was conducted in the field of Al-Musaib Technical Institute, Foundation of Technical Education, at 2010 , at Massy Ferguson ( MF- 399) tractor with chisel plow in the various tillage depths as well as effect of tractor speeds in clay loam soil .The experiment was studied two factors: - included tillage depths (12.5,17and24 cm). Three ground speeds of tractor included 3.06,4.68 and 6.66 km/hr , The properties which were studied including fuel consumption, soil penetration resistance , slippage percentage and practical productivity .The research was performed by applying the factorial experiments according to the completely randomized design with four replications and data were analyzed statisticalyl. Mean values of each treatment were compared using LSD at the 0.05 level of confidence to test significance. The results showed the following : increasing of tillage depths from 12.5 to 17 and 24 cm caused an increasing in fuel consumption, Soil penetration resistance and slippage percentage, and decrease in the practical productivity ,Tillage depth 12.5 cm indicated significant superiority up on tillage depths 17 and 24 cm in achieving lower fuel consumption, Soil penetration resistance and lower slippage percentage while tillage depth 24 cm achieving higher practical productivity, Increasing ground speeds of tractor from 3.06 to 4.68 and 6.66 km/hr caused an increasing in fuel consumption. Soil penetration resistance and slippage percentage and practical productivity, Ground speed of tractor 3.06 km/hr achieved lower fuel consumption, and lower slippage percentage, while ground speed of tractor 6.66 km/hr indicated significant superiority up on 3.06 and 4.68 km/hr in achieving higher practical productivity in tillage depth 12.5 cm . | ||
