As to certain the increases the farm income that predominantly relies on human resources by mechanizing Welsh onion harvesting a tractor mounted onion harvester was developed in this study. An experiment for evaluating harvesting performance was performed for the developed onion harvester in an actual onion farm. the harvest performance was evaluated at the tractor running speed of 5.0 cm\s, 11.4 cm/s and 15.8 cm/s, by comparing the operating efficiency ,harvest rate, and damage rate of the welsh onion harvester. The performance of the harvester was rated as very good, with a 100% harvest rate, regardless of tractor running speed.
The developed onion harvester is believed to improve the labour productivity and cultivation environment of onion farmhouse by the mechanization of the harvesting process that is currently associated with the largest amount of labour hours. The present research work has been carried out to bring out the reliable solution for harvesting of onion crop. The harvesting of onion crop is the labour intensive operation.
