Abstract
Rice is the most important food crop of India which is grown in about 43.86 million hectare. In India the production touches 112 MT milled rice used to feed 0.8 billion peoples that is 65% of the population.Rice is grown by manual transplanting of young rice seedlings in the puddled field in bending and squatting posture, which is very drudgerious operation. Prior to transplanting, puddling is done to prepare a soft seedbed for maintain water level in the field. Generally, animal drawn puddler, tractor’s cage wheel and power tiller operated rotary tiller were used for puddling operation.A self-propelled puddler developed at IIT Kharagpur for rice crop was tested in sandy loam soil of Kharagpur district in India. The average value of puddling index and the puddle depth was found to be above 78 % and 107 mm, respectively. The puddling with self-propelled puddled was found to be at par with that of rotary tiller.
