To ease the situation of planting operations, this study developed a single-row paper pot transplanting system for vegetables. Trials were conducted to determine the rates of manual transplanting, paper pot making, arranging seedlings in paper pots, and mechanical transplanting. The manual transplanting rate was 84.20 plants/h to 113.30 plants/h (highest rate from transplanting cabbage). The manual paper pot-making rate was 57.08 pots/h to 68.41 pots/h (highest rate from 50.8mm-spaced pots). The machine-aided paper pot-making rate was 769.66 pots/h to 843.17 pots/h (highest rate from 50.8mm-spaced pot). The rate of arranging seedlings in paper pots was 34.98 plants/h to 36.80 plants/h (fastest rate from cabbage). The paper pot transplanting rate was 9,391 plants/h to 14,882 plants/h (fastest rate from spinach). Respondents accepted the paper pot transplanter. Using a paper pot transplanter, the return on investment is 90.16%. Mechanization results in an additional cost (machine and paper pots), nonetheless, farmers' field exposure time during planting has been reduced by about 99% and the ergonomics of using paper pot transplanter ease the condition of planting operations of farmers. Paper pot design and transplanter modifications were suggested to further improve the paper pot transplanting system.
