“…The increment of ash content might be attributed to the role of humic acid in increasing root growth, nutrient uptake and consequently stimulated plant growth (Fernandez-Escobar et al, 1999), which leads to increasing calyx dry weight then increasing total solids. Our results of moisture and ash content are in harmony with those of Suliman et al (2011) on Hibiscus sabdariffa L. The high acidity of plants treated with humic acid compared to the non-treated plants could be attributed to the utilization of additional carbon source provided from the organic fertilizers in the production of organic acids, which are responsible for the fruit acidity (Aminifard et al, 2012). The enhancing effect of humic acid on titratable acidity was in parallel with the findings of Aminifard et al (2012) on hot pepper and Fallahi et al (2017) on Roselle.…”

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.

“…Micronutrients play an active role in the plant metabolic process from cell wall development to respiration, photosynthesis, chlorophyll formation, enzymes activity, nitrogen fixation etc. Micronutrients work as a co-enzyme for a large number of enzymes (Ding et al 2004, Lawrence et al, 2011, Poldma et al, 2011, Ameri et al, 2012, Aminifard et al, 2012. It also plays an essential role in improving yield and quality and highly required for better plant growth and yield of many crops (Alam et al, 2010).…”

The importance of studying in agriculture the impact of individual micronutrients on the course of production processes and their impact on the quality of garlic is an important issue. The influence of iron, zinc and boron in different norms against the background of the recommended norm NPK. The research results showed significant increasing of chlorophyll content by the application of Iron 10 and 20 kg/ha – 12.0 and 16.4%; by the application zinc increasing of chlorophyll was significant on all variants – 15.1; 48.0 and 30.4% in respectively with the norms. By the application of boron content of chlorophyll was the least significant – 10.9% at the maximum norm – 6 kg/ha. The dynamic activity of antioxidant enzymes was similar before the dynamics of growth processes. The activity of the enzyme was highest for the optimal norms of micronutrients. Among the studied complex of the enzymes most significantly increases actityes catalase (CAT) and glutathione S-transferase (GST). Zinc has the greatest effect on the formation of bulb mass. The increase in bulb weight by the application of zinc fertilizer was significant in all variants – + 14.3–20.0% to control. Fertilization with microelements in the minimum and optimal norms contributed to a significant increase in yield, the application of maximum norms led to a decrease in productivity in general, except boron, where plant productivity increased with increasing norms, from which it can be concluded that garlic needs were insufficient 6 kg/ha is not the maximum. With fertilization of iron in the norms of 10 and 20 kg/ha the yield increase was 4.26 and 4.85 t/ha and was significant, by the application of 30 kg/ha of iron the yield of garlic was higher than the control by 3.70 t/ha. Zinc fertilization had the best effect on yield increase (+ 4.25–5.12 t/ha). A significant increase in yield for boron fertilization was observed at the maximum rate (+3.26 t/ha). By the application of zinc and boron contributed to the extension of the marketability of garlic bulbs to 210 and 220 days for warm storage and up to 240 and 260 days for cold. During warm storage, after 210 and 260 days – during cold storage there was a mass germination of the cloves. Bulbs of the control variant and y the application of iron germinated after 120 and 180 and 190–210 days according to the variant and storage regime. Further research is to study the combinations of the studied micronutrients on physiological processes and biochemical parameters and to optimize their norms for local fertilization.

Baldotto, 2015) that acts in several phases of the vegetable physiology such as growth, development, photosynthetic structures of respiratory activity (Costa et al, 2008); changes on biochemical pathways as primary and secondary metabolism (Trevisan et al, 2011;Aminifard et al, 2012;Nardi et al, 2017). Due to all these beneficial effects of elicitors on plant productivity, they have attracted the interest of farmers and companies.…”

In function of the green revolution the indiscriminate use of agrochemicals and pesticides in agriculture has been also shown in the production of medicinal plants, resulting in the increase of productivity but with high residual contamination and low rates in the production of secondary metabolites responsible for the biological and pharmacological activity in vegetable drugs. In another hand, new techniques of elicitation has been applied to stimulate the medicinal plants production through the organic and agroecological management, contributing for the increase of performance, quality and production. In this context, it is aimed with this review to present such as the humic substances: fulvic acid, humic acid and efficient microorganisms which influence and help the ontogeny and the secondary metabolites production of medicinal plants. The reviewed articles show that the use of fulvic acid, humic acid and efficient microorganisms in the production of medicinal plants contributes on the increase of biosynthesis, secondary metabolites production such as coumarins, alkaloids, phenylpropanoids and essential oils, as well as the increase of nutrients absorption, growth and development of species.
