摘要

The effect of blade width and spading frequency on various dependent variables, i.e. specific soil resistance, energy consumed per unit volume of soil moved, weighted mean clod size, soil bulk density, cone index and cone index ratio were studied. The experiments were conducted in a soil bin on soil having 15.7 % clay, 53.6 % silt, and 30.7 % sand. During experimentation, moisture content of soil was maintained between 13 and 14 %. Blade widths used were straight, 10 cm (W_1) and 15 cm (W_2) and spading frequencies F_1 (1.85 Hz), F_2 (2.31 Hz), F_3 (3.08 Hz) and F_4 (4.62 Hz). The values of dependent variables increased with increase in blade width and decreased with increase in spading frequency. However, the cone index ratio decreased with increase in blade width and increased with increase in spading frequency. Hence, for maximum soil pulverization and optimal specific soil resistance and energy consumption, smaller blade width and higher spading frequency were found to be better.
