Abstract
Field experiment was conducted to study effect three design shapes of moldboard plow shares (Conventional share, Hoe share, and Sectioned share), two levels of the depths (10-20 and 20-30) cm and two different speeds (3.5) km/h and (5.3) km/h according to design RCBD method of split-split block design, Then their effects in performance parameter (actual productivity, performance efficiency, soil distribution volume, and coefficient of working width exploitation). And soil physical properties (bulk density and porosity). Results showed that the Sectioned share significantly surpassed on Conventional share and Hoe share in all performance parameter and soil physical properties, The different levels of depths and speeds had significant effects in all the performance parameter and soil physical properties. All interactiong (speeds and depths) had significant effects in all performance parameter and soil physical properties exceptionality coefficient of working width exploitation, and bulk density. All interactions (speeds and shares) and (speeds and depths and shares) had significant effects in all performance parameter while there were no significant the differences in soil physical properties. All interactiong (depths and shares) had significant effects in all performance parameter exceptionality practical productivity criteria, while there were no significant differences in soil physical properties.
