A furrow opener comprises an opener body for mounting on a cultivator shank for movement therewith in a forward working direction and which supports a knife on a front end to deposit a fertilizer row and a wing attachment at a rear end to deposit paired seed rows in the ground. The bottom side of the opener body is stepped in profile between the knife and the wing attachment to comprise an enclosed front portion extending generally horizontally rearward from the knife, a step portion which extends upward from the front portion and primarily locates a fertilizer outlet therein and a rear portion extending generally rearward from the step portion to the rear of the opener body. The fertilizer outlet in the step portion primarily faces rearwardly and is more vertical in orientation than the enclosed front portion of the bottom side of the opener body ahead of it to shield the fertilizer outlet from the wake of earth displaced by the knife.
