Tillage is one of the most important operations in agriculture. Tillage not only helps to provide favorable
soil conditions for plant growth but also improves the physical condition of the soil. It also affects the
moisture holding capacity of the soil. An experiment to study the influence of various tillage operations
on the physical properties and infiltration characteristics of soil indicated. It was observed that moisture
content was highest in rotavator tilled soil (17.75%), and lowest in M.B. plough tilled soil (14.68%). Bulk
density was found to be highest in M. B. plough (2.35 Mg m-3) while it was lowest in M. B. ploughed and
rotavator tilled soil (1.3935 Mg m-3. The infiltration rate was lowest in the undisturbed soil (0.01 cm
min-1) and was highest in the soil tilled with M. B. plough (0.1 cm min-1). The infiltration rate was higher
in M.B. ploughed and rotavator tilled soil (0.09 cm min-1) as that of tilled by rotavator (0.03 cmmin-1). It
was observed that seed germination was highest (90%) while lowest (85%) in rotavator tilled soil
