Abstract

A PTO-powered one-way disk plow was developed to plow PADDY FIELDs with excessive soil compaction. The plow was operated in the rice fields after paddy harvest at peripheral disk velocity to ground speed ratios of 3.0, 2.2 and 1.7 at four soil depths. The factorial experiments were conducted as randomized complete block design in three replications. The performance of the POWERED DISK PLOW was compared to that of the standard disk plow and pre-till soil conditions. The study indicated that the rotary plow markedly decreased aggregate size since the clod fineness was improved by an average of 29.5% compared to the standard disk plow. Smaller clod mean weight diameters (MWD) were obtained at low levels of velocity ratio (higher tractor speeds). The cross section of the soil tilled with the powered plow exceeded the standard disk by an average of 25% for the speed range studied. The disturbed cross sectional area was larger at higher speeds. Average cone index reductions of 50 and 63 % were determined in depth ranges 10-15 and 15-20 cm, respectively. It was found that an increase in the tractor speed was associated with corresponding decrease in the soil cone index at 10-15 and 15-20cm depth ranges. Therefore, for better penetration, the tractor speed should be kept at the fastest possible level. The maximum working depth was 16 cm for the standard disk plow but was 20 cm for –the POWERED DISK PLOW, i.e., a 25% increase. The study revealed that the POWERED DISK PLOW resulted in a significant decrease in soil cone index and improvement of other factors as compared to pre-tillage conditions and the standard disk plow.
