COMPREHENSIVE EVALUATION OF DIFFERENT TILLAGE SYSTEMS FOR SUGAR BEET PLANTING

Experiments were conducted in the agricultural experiments station, Faculty of Agriculture, Cairo University at Giza. Three soil tillage systems were identified. The first system consisted of chisel plough followed by disc harrow, the second system consisted of mouldboard plough followed by disc harrow while the third system consisted of disc plough followed by disc harrow). The area was divided into 27 plots to test the performance of the three tillage systems, while working at three forward speeds and three ploughing depths. The comprehensive analysis of the studied physical and technical parameters led to the conclusion that the chisel plough provided the suitable seed bed at highest rate of performance and lowest specific energy consumption when executing the soil moving operation at 6 Km/ h speed and at 10 cm depth.
