Effect of numbers of blades and speed of tillage in the performance

Abstract

A two-tiered global experiment was carried out in a mixed clay field in southern Baghdad. The first factor consisted of two rotary plows that differ in the number of rotary weapons distributed to the circumference of the plates (disks) distributed on the rotary horizontal column of the first rotary plume Galuch made in Portuguese and the number of weapons in the plate (4) weapons, the second factor four speed of the tractor is 2.62, 5.10, 7.55 and 9.23 km.-1 hour for the purpose of comparing the performance of the two circular plows under 12 cm depth and know the percentage of the slip and distance between strike and other Rotary plow and process productivity And the percentage of soil mass of less than 5 cm (block / m -2) was used in this study. The design of the complete random strata was used with three replicates. The differences between the coefficients were tested in a less significant difference at the 5% probability level. The results of the experiment showed the moral superiority of the Japanese kubota type in the recording with the highest practical productivity of tillage 0.7117 ha. -1 hour and the soil size is 854.1 m3. -1 hour and the lowest sliding rate is 3.94%. The Portuguese plow recorded the best land mass of 96.19% and the lowest distance between blow and other for plow weapons is 0.180 m. The operating speed of the tractor exceeded 9.23 km., -1 hour significantly. The highest productivity is 1.0876 ha. Hour -1 and the soil volume is 1256.2 meters.
