Using the chisel plow with different types of tines distribution and its effect in some performance indicators

This research study included evaluating the effect of patterns of distribution of chisel plow tines on field performance at different operating factors by studying three factors .The first is patterns of distribution of the chisel plow tines at three levels (3-4-4), (2-4-5) and (2-5-4) and the second factor is the depth of tillage at two levels (10-12) cm and (15-17) cm and third factor is the speed of work at two levels (3.21) km/h and (4.72) km/h . and the effect of this is on the following characteristics (draw bar power, slip ratio, actual productivity, energy consumed, specific resistance to traction, , specific energy). Used Randomized Completely Block Design (RCBD) with the split – split plot Designs system in implementing the experiment, Duncan's multiple range test was used to find significant differences between the averages of the treatments at the probability level (0.05). The results showed that the second distribution pattern was significantly superior, as it recorded the lowest values for the draw bar power , slip ratio, and energy consumed, while the third distribution pattern was significantly superior in achieving the lowest values for the characteristics of specific resistance and specific energy, and achieved a plowing depth of (10-12) cm significant superiority by recording the lowest values for the characteristics of draw bar power , slip ratio, and energy consumed, and the highest values for actual productivity, while the depth (15-17) cm was significantly superior by recording the lowest values for the characteristics of specific resistance and specific energy and the speed (3.21) km/h was significantly superior by achieving the lowest values for the characteristics of draw bar power, slip ratio, energy consumed, specific resistance , and specific energy, while the speed (4.72) km/h was significantly superior by achieving the highest values for the value of actual productivity.
