| Abstract | ||
| The research was implemented in the field of Telkief location (moderate rain full area ) in Ninevah province with clay silt soil texture , during 2012 season to study the effect of four tillage depths (10-12 , 12.1-14 , 14.1-16 and 16.1-18)cm which represented the main plots and two blade shapes (Tradi- tional and Developer) which represented the sub–plot, on some power requi- rements (Tractive force, Tractive power ,slippage rate, lost power of slippage , fuel consumption and actual productivity) and some of physical properties (disturbed soil volume ,soil resistance to penetration and specific resistance for soil). Split plot under Randomized Complete Block Design (R .C.B.D) with three replications was used under possibility level of (0.05). The results showed that : The First plowing depth (10-12)cm gave significant reduction in the value of (force and power requirements ,slippage rate ,fuel consumption ,where as the higher value were obtained in actual productivity hrha) comparing with other depths. The developer blade shapes recorded higher value in actual productivity and lower values in (force and power requi- rements, slippage rate and lost power of slippage, fuel consumption and specific resistance for soil). The interaction between the first tillage depth (10-12)cm with the blade shape developer gave a good results in (tractive force and power ,slippage rate and fuel consumption)while the tillage depth (16.1-18)cm with the traditional blade shape gave higher values in soil resistance to penetration and specific resistance for soil and lower value in actual produ- ctivity . | ||
