Abstract

Field experiments were carried out during the two successive summer seasons of 2015/2016 and 2016/2017. The experiments were accomplished in an open field located at Bader region, El-Beheira Governorate, Egypt to evaluate the effects of humic acid, indole butyric acid (IBA), and arbuscular mycorrhizal fungi (AMF) (Glomus mosseae) individually on vegetative growth, yield, and phytochemical characteristics of Hibiscus Sabdariffa (Roselle jamica). Experimental field plots were designed as randomized complete block design (RCBD). The obtained results of the two seasons, generally, showed that all treatments (HA, IBA, and AMF) individually enhanced the vegetative growth, yield of calyx, and phytochemical parameters of Roselle plants. The HA treatment was the most effective in enhancing most of the studied parameters and might be recommended for enhancing the vegetative growth, yield of calyx, and calyx phytochemical components of Roselle plants under the environmental conditions of Bader region, El-Beheira Governorate and other similar regions.
