In this study, punching force, stress, and energy of Yalova 12 and Banko onion varieties were examined. These varieties are grown in Bursa region and having an important place for exporting in our country. The effects of storage (right after harvest and after one month of storage) and the position of onion (radial and axial) along with the variety of onion were examined for punching the onions. According to the results, the variety had no effects on punching, but the position of onion was found important statistically.
