| dc.description.abstract | The work was carried out at the Kelappaji College of Agricultural Engineering and Technology, Tavanur. The six – row rice transplanter was originally designed for mat type seedlings. Considering the importance of a transplanter using conventional type seedlings, the above transplanter was modified. The modifications were completed in three stages. The performance evaluation of the modified six row rice transplanter was conducted after each stage of modification. The average number of seedlings per hill could be reduced from the average value of six seedlings per hill before modification to 2.27 seedlings per hill after the modifications. The missing hills percentage was brought down from 20.83 per cent to 5.55 per cent and the floating hills percentage was reduced from 10 to 5.55. Percentage of damaged hills was reduced from 23.3 to 8.8. The field capacity of the machine was improved from 0.0139 ha/hr to 0.0162 ha/hr and field efficiency from 48.26 percent to 56.87 per cent. The use of the modified transplanter is profitable if it is operated beyond one hectare per annum. It gives a saving of Rs. 618.00 per hectare compared to the conventional hand transplanting giving a 2. 4 times reduction in total cost. The pay back period of the modified transplanter is 2.24 years when the annual utilization is 2 hectares per annum and 1.13 years when the annual utilization is 3 hectares per annum. | en_US |
