Abstract
The study aimed to find out the effect of operating hours during ploughing operation on the proportion of erosion in the share of mould board plough trio, and its effect in the percentage % of deviation both vertical and lateral for the plough, in addition to the cohesion of soil on the surface of the share kN.m-2 and the efficiency of power exploitation m3.MJ-1, where four levels of ploughing operating hours has been adapted 50, 100, 150 and 200 respectively. The results showed that in 200 ploughing hours, a highest percentage of erosion, deviation vertically and laterally, in addition to that a highest percentage of soil cohesion on the efficiency of power exploitation has been recorded. While a lowest percentage has been recorded in 50 operating hours for the erosion of share surface, vertical and lateral deviation, and lowest soil cohesion on the share surface in addition to the highest efficiency of power exploitation. However; the highest ejective significant correlation coefficient found between the percentage of erosion in the front share of the plow and the percentage of erosion in the middle share of the plow. Moreover; between the percentage of vertical deviation and the percentage of lateral deviation. On the other hand; a highest significant proportioning correlation coefficient was found between the efficiency of power exploitation with the proportion of lateral deviation and the proportion of the erosion for the three shares of the plough (front, middle and rear).
