MCQ (Single Correct) +4 −1
Topping and de-suckering are not practised generally for which type of tobacco?
  • Wrapper Tobacco (Option 3): Cigar wrapper tobacco leaves must be ultra-thin, silky, elastic, light in color, and mild with low nicotine content. Topping stimulates secondary leaf thickening and nicotine synthesis, so wrapper tobacco plants are left untopped (or topped very late/high) and de-suckering is avoided to keep leaves fine and tender.
  • Chewing Tobacco (Option 1): Requires thick, coarse, leathery, dark leaves with high nicotine and gums; severe low topping and rigorous de-suckering are mandatory.
  • Cigar Filler & Binder (Option 2): Topped to promote moderate body and nicotine development.
  • Bidi Tobacco (Option 4): Topped strictly at 12–14 leaves followed by repeated de-suckering to maximize leaf thickness, spangle development, and high nicotine. (Correct answer: Option 3)
