I would argue that the poet is drawing line between seeds and rebirth, with echoes of Christ's death and resurrection. If we reference the Bible passage, John 12:24, which says "Truly, truly, I say to you, unless a grain of wheat falls into the earth and dies, it remains alone; but if it dies, it bears much fruit." Coming back to the first couple of the poem, in which we see "His dear, his loved, his only one", we again see echoes of Christ being "the firstborn of God's creation" and "His beloved Son". Perhaps the poet is trying to show that the Seed-Merchant still hopes to see his son again one day (after Christ's second coming or in Heaven), or at the very least sees a legacy left behind that is bearing fruit in the soil and seeds in his own hand.
