A growth chamber study was conducted to determine the implications of the dual application of humic acid (HA) application and arbuscular mycorrhizal fungus (Glomus intraradices; Gi) inoculation on pepper cv. Demre. The treatments comprised: 4 different HA levels (0, 500, 1000 and 2000 mg/litre) and 2 levels of Gi (Gi absent and Gi present) applied to growth media supplemented with 50 mg NaCl/kg before seed sowing. Hypocotyl length, cotyledon width and length, stem-neck diameter, shoot length, leaf number, leaf area and shoot and root dry weights of the seedlings were determined. Mineral contents of plant shoots and roots were also determined. Almost all of the seedling growth parameters and plant nutrient contents were positively affected by both HA application and Gi inoculation. It was observed in the interaction of these 2 factors that HA application triggered and increased the positive effects of Gi inoculation. Therefore, it is advisable that the dual application of HA and Gi could promote much more growth in pepper seedlings grown in salty condition.
