摘要

Organic tobacco consists of a new industrial crop product. Also, organic transplant production is the major problem for organic agriculture in Greece. Thus, field experiments were conducted to determine (a) the effects of organic and conventional float systems on tobacco seedlings quality and (b) the effect of organic and inorganic fertilization on the growth, yield and nicotine content of flue-cured and oriental type of tobacco (Nicotiana tabacum L.). Experiment (a) was conducted as complete randomized block design with three replicates and two treatments (organic and conventional float system). Experiment (b) was conducted as split plot design with three replicates, two main plots (flue-cured and oriental tobacco) and two sub-plots (organic and inorganic fertilizers). Our results (Experiment a) clearly indicate that there were no significant differences between the organic and conventional float systems for root biomass of tobacco seedlings. Conventional fertilization treatment is responsible for the production of seedlings with high water content (82-83%). Moreover, in both tobacco types (Experiment b), there were no significant differences between the organic and inorganic fertilization concerning the height and yield of tobacco crop. The yield in the oriental tobacco was less than in the Virginia tobacco type. In both tobacco types the use of organic fertilizer increased the nicotine content and N% of leaves. High correlation coefficient (r=0.88, p<0.001) between N% and nicotine content of leaves was found. The nicotine content of leaves in oriental tobacco type was always higher than that in Virginia type. Controlled release of nitrogen in organic fertilizers may be a useful practice for increasing nicotine content in tobacco crop.
