Production potential of cavendish cultivars (Musa spp. AAA) under greenhouse and field conditions in subtropical areas of Turkey

The objective of this study was to evaluate the production potential of banana cultivars, 'Grand Nain', 'Petit Nain', 'Poyo', 'Williams' and 'Basrai', as alternatives to the 'Dwarf Cavendish' for open-field and greenhouse cultivation in subtropical conditions. Stem circumference, stem height, total leaf number, bunch stalk circumference, days from shooting to harvest, number of hands per bunch, number of fingers per bunch, finger circumference, finger length and bunch weight were measured in open-field and greenhouse cultivation. Cultivars 'Williams' and 'Grand Nain' were superior to 'Dwarf Cavendish' in greenhouse cultivation, while these two cultivars and 'Petit Nain' and 'Basrai' were superior to 'Dwarf Cavendish' in open-field cultivation. 'Poyo' was not suitable for greenhouse cultivation because of its excessive height and for open-field cultivation due to its sensitivity to wind damage. Greenhouse cultivation of bananas was superior to open-field cultivation for all cultivars with increases in yield of 19 to 28% according to the cultivar.
