Development and Performance Evaluation of Tractor Operated Onion Harvester

Onion (Allium Cepa L) is one of the most important crops of India covering 10.44 % of total area under vegetables in the country. The developed onion harvester was able to dig the onion plants with blub and laid these on the surface of bed unevenly The theoretical field capacity of harvester was found as 0.57 ha/h while effective field capacity was 0.45 ha/h with the field efficiency of 78.95 %. The savings in time required, energy consumed and harvesting cost of onion were 87.64 %, 46.23 % and 78.86 % respectively over manual harvesting method.
