Valuable because it provides many things.

Explanation:

The poet conveys that he has nothing else to give her except his poem. He compares his poem to 'a bowl full of yellow corn' to 'warm her belly in winter' and 'a scarf to wear over hair' and 'cover her face'. Thus, this symbolizes that the poem has several roles to play for his beloved beginning from filling her belly to and ending from serving as a scarf to provide warmth and comfort to her. Thus, this symbolizes his love for her and hence, it becomes valuable as it grants many things to her.
