Effect of Cutting Type and Humic Acid on Growth and Root Traits of Fig ( L.) Ficus carica Wazeri cv. Saplings

Abstract

Abstract: Greenhouse trial was carried out at University of Anbar, Iraq, during the growing season of 2018 to study the effect of the cutting type (terminal, middle and basal) and the application of humic acid 0, 2 and 4 ml/litter on some traits of vegetative and root growth of fig. The humic acid was added to the cultural media in three stations. The different types of cutting showed a significant effect on all vegetative and root growth traits (except the dry weight of the vegetative system). Basal cuttings resulted in maximum s saplings height (49.86 cm), branches per sapling (7.69), stem diameter(12.82 mm), sapling leaves area (180.5 cm) and root length (41.61 cm), respectively. The addition of 4 ml/ litter concentration gave the maximum saplings height, number of branches, -1stem diameter, sapling leaves area, dry weight of vegetative system, roots length and dry weight of the root system (53.42 cm, 7.58 branch sapling, 13.00 mm, 176.2 cm, 21.30 g, 42.14 cm and 8.43 g, respectively). The basal cuttings resulted in positive effect on vegetative and root traits as compared to the middle and terminal cuttings.
