Abstract

Two foliar applications of B at the rate of 1 kg ha−1 at 30 d and repeated at 42–45 d after seeding or a single preplant broadcast application of 2 kg B ha−1 provided excellent control of brown-heart in rutabagas (Brassica napobrassica Mill.). Similarly, two-application treatments initiated 40 d after seeding or later failed to prevent brown-heart at some locations. Root yields were slightly decreased by the two foliar sprays of B applied at five different stages of growth and by the single preplant soil application of B. Key words: Foliar treatments, boron, brown-heart, rutabaga
