| Abstract | ||||
| This research work was carried out in Nobaria area to study the performance of moldboard plow in the new reclaimed soil to investigate proper tillage operations by using 3-bottoms moldboard plow with the 80 HP tractor (60 kW). The results show that the optimum working speed was 6.75 km/h (at no-load). At this speed the average slippage was 7.4%, 11.1% and 12.59% at tillage depths 20, 25 and 30cm respectively (less than 15%, allowable limit) and the power requirement 19.1, 22.5 and 26.0 kw respectively. The fuel consumptions were 7.98, 8.15 and 8.9 kg/h and the field capacities (or productivity) were 1.17, 1.13 and 1.11 fed/h at 20, 25 and 30cm tillage depths respectively. Also, the plow was working in stability case with the tractor, where both vertical and horizontal deviations were non-significant, and the loosening degree was 29, 30.8 and 33% of tillage depth, and the clods were in the acceptable range where the soil crumbling degree was 85.4, 86.07 and 87.01% at tillage depths 20, 25 and 33 cm in primary tillage. The vegetation burying degree was 97.24, 97.64 and 97.79% at tillage depths 20, 25 and 30cm respectively. | ||||
