This variety was created as a result of research by the Ministry of Agriculture, considering that agricultural productivity has decreased due to weather problems. They have the same shape as red onions in general.
That’s what I can share on this occasion regarding the types of shallot varieties that are good for peat soil. Hope it is useful.
