Nicotine can be produced from green tobacco for use as an environmentally sound pesticide and fodder protein. Varieties (hybrids) belonging to the species Nicotiana rustica are best for this purpose. As the results of selection, rapidly developing varieties and F1 hybrids are available where the nicotine content of the leaves is 6-8 o/o. Experiments were carried out to elaborate a new production technology for double purpose utilization. One precondition for this is the provision of satisfactory nutrient supplies and irrigation. A plant density of 60-70.000/ha proved the most suitable. The nicotine content of green tobacco harvested together with the stem, side-shoots and flowers was in excess of 2 o/o over the average of several years, while the protein was over 20 o/o and the green mass around 50 t/ha. The further chopping and pressing of green tobacco harvested as silage can be easily mechanized and the product can be successfully preserved (using Na benzoate). Calculations indicate that more than 100 kg/ha nicotine base for plant protection and pharmaceutics can be produced, while the protein yield is 15 kg/t, with an annual yield of 700-800 kg/ha.
