Transplanting of paddy remains a labour-intensive operation, involving significant human effort and high input costs. The performance of a paddy transplanter is also affected by the age of seedlings and the status of sedimentation after puddling. This study was undertaken to optimize two parameters, namely, seedling age and sedimentation period after puddling in order to maximize the output from a remote-controlled, root-wash-type paddy transplanter. The seedling age was varied from 15 to 30 days, and the sedimentation period from 8 to 48 h after puddling. Planting efficiency, effective field capacity and field efficiency were considered as dependent parameters. Using Response Surface Methodology (RSM), a statistical tool, a total of 13 experiments were conducted in a systematic manner. The measured dependent parameters were recorded and analyzed. It was found that both seedling age and sedimentation period significantly influenced planting efficiency. The study concluded that the maximum planting efficiency of 94.8%, with an effective field capacity of 0.059 ha h-1 and a field efficiency of 65.51%, could be achieved at a seedling age of 24 days and a sedimentation period of 30 h. Results of this study will guide in selecting the seedling age and sedimentation period to achieve maximum output from the remote-controlled, root-wash-type paddy transplanter.
