Abstract
In plot trials at 4 sites in 1966 Burley tobacco was given 100, 200 or 400 lb N/ac) and was (a) not topped, no suckers removed, (b) topped, (c) topped and suckers removed, or (d) given MH at 170 mg/plant. Early and late harvests were made. In 1967 similar experiments were carried out using N at 0, 40, 80, 160, 240, 320 or 400 lb/ac. Leaf DM increased with rate of N fertilizer up to 200 lb/ac. Sucker removal increased leaf DM but not stalk, top and sucker DM.
