Solution(By Examveda Team)

Long-day onion variety is Brown Spanish.
Long-day sweet and storage onion varieties do well in the northern states that have between 14 - 16 hours of daylight length.
Long-day sweet onion varieties generally mature a few weeks before long-day storage onion varieties and will keep from one to four months, so eat them first.
