Description: Traditionally, flue-cured tobacco is harvested by removing two or three leaves at a lime, starting at the bottom of the stalk, over a period extending from 4 to 6 wk. This procedure accounts for 50% of the labour input to produce the crop. Mechanization of this traditional method has shifted the labor costs to capital investment, but the costs are still considerable. The high cost of conventional product has led tobacco manufacturers to utilize waste and non-tobacco products in homogenized sheet form as a blend in their products. In addition to economy, it has been shown that homogenized sheet tobacco used as a low-cost filler is biologically less active than conventional tobacco (Wynder and Hoffman 1967). These factors led the Agriculture Canada Tobacco Research Station at Delhi. Ontario to investigate a tobacco product grown specifically for homogenized sheet production and suited to mechanical harvesting. Early research indicated that a suitable low-cost product could be produced if it was grown at high density, once-over, whole-plant harvested, chopped into pieces and cured in shallow beds. The resulting product showed promising quality and gave the prospect of low-cost production, provided the crop could be harvested mechanically (Walker 1975).
