The Effect of Green Manure and Irrigation on Morphological and Physiological Characteristics of Virginia (Flue-Cured) Organic Tobacco (Nicotiana tabaccum)

A. Karkanis, D. Bilalis and A. Efthimiadou

Abstract:
Field experiments were conducted to determine the effects of drip irrigation and sprinkler irrigation and green manure on morphological and physiological characteristics of tobacco. The experiment was laid out in a split plot design with four replicates, two main plots (drip and sprinkler irrigation) and three sub-plots (vetch as green manure, red clover as green manure and control (without fertilization)). Green manures increased leaves width and length, diameter of stem and roots and the most significant impact was when vetch was applied to soil. Physiological characteristics were significantly influenced by the green manures. The lowest stomatal conductance and photosynthetic rate were found in control plots. Drip irrigation was characterised by a smaller amount of water applied to the soil. However, drip irrigation increased the length of leaves. The roots and stem diameter were not affected by the irrigation systems. Also, 86 days after transplanting, the lowest stomatal conductance and photosynthetic rate were found in plots irrigated with sprinkler system.
