The main contrasts between Andrew and Robert are presented with the help of these attributes of their characters.

Explanation:
Andrew and Robert are two brothers in Eugene O'Neill's play "Beyond the Horizon"
They are very similar in some attribute, while in some other attributes, they are at opposite poles from each other.
Andrew is described as on who has much interest in the fields, he takes all the pain to keep family's farm and fields in good shape. Robert, on the other hand, is totally indifferent to what is happening at farm and fields. He is characterized as having a poetic and delicate nature - reading books, and thinking about adventurous journeys occupy much of his time.
There is no contrast between Andrew and Robert on the bases of caring for their family. They both care much for their family.
Andrew is not resentful about Robert leaving the farm. He just says that everyone at farm including Andrew himself will miss him a lot.
