Abstract: Rice is one of the most important food crops of India, which has 44.11 million ha of the area under cultivation with a total production of 105.48 million tonnes (2016-17), which is second only to China. In Odisha, rice covers about 67 per cent of the cultivated area. Out of the total area under paddy, 2.2 million ha is sown by direct broadcasting of paddy seeds and 1.7 million ha by transplanting, which includes both manual and mechanical transplanting. Although, the numbers of rice transplanters in the state in the past 10 years has climbed to a total of 2990, the majority of the area is still transplanted manually. The acceptance of the mechanical transplanter is lower due to the extra cost, skill and time required for raising the mat type seedlings used in these transplanters. Root wash type paddy transplanter has been a long-awaited demand of the farmers. Keeping this in mind, a suitable root wash type transplanter has been developed in earlier in CAET which can use the traditional root wash type seedlings used by the farmers. But the transplanter needed further modification in order to reduce the weight, unproductive hills and to make it more compact. Based on this, modification and evaluation of the two-row root wash type transplanter were done. It was observed that the percentage of missing hills, floating hills, buried hills and damaged hills were 5.65%,4.25%,4.25% and 1.40% respectively. The total unproductive hill was found to be 15.58 per cent which was 50.77 per cent lower than the existing transplanter. The actual field capacity, theoretical field capacity and field efficiency were found to be 0.0179 ha/h, 0.0265 ha/h and 67.24 per cent respectively, which were 17.87, 7.69 and 8.16 per cent higher than the existing transplanter. The average increase in the heart rate and oxygen consumption rate were found to be 60 bpm and 0.63 l/min. The fabrication cost of the transplanter was found to be ₹4960.00 and the cost of transplanting per ha was observed to be ₹2631.00 which was 69.93% lower than manual transplanting (₹ 8750.00). The payback period was found to be 0.86 years for the modified transplanter.
