Abstract
Abstract This study was carried out at two sites of different soil texture, clay and a clay loam during the season of 2005 – 2006 In Mosul .A plough of three different shank shapes have been used . These shapes were vertical, inclined forward and curved with two plough depths of 8-12 cms and 13-17 cms successively with three speeds 3.70, 7.15 and 9.64 km/hour. In order to study the effect of the shank shape on the power requirements -which include the draft force, rate of fuel consumption, slippage ratio and the power loss due to slippage. The two experimental farms have been designed by the use of (RCBD) with three factors and replications. The main results of this study, The vertical shank outperformed at the first site and the inclined forward outperformed at the second site in recording the lowest requirement with their means, the 8-12 cm depth outperformed at the two sites with their means in recording the lowest power requirement, the (3.70) km/ hour speed recorded the lowest power requirement except fuel consumption at the two sites with their means, The second site (clay loam texture) outperformed records the lowest power requirements.and at the effect of interaction between the sites, shank shape, depth and speed on the studied properties the inclined forward shank at depth of (8-12) cm and at speed of (3.70) km/hour gave the lowest power requirement at the second site except fuel consumption.
