“…Generally, the greatest values were achieved with the interaction treatment of salinized water at 1.4 dS/m in combination with potassium humate at 3000 ppm. Similar findings were recorded by Burhan and Al-Taey (2018) on dill and Badran et al (2019) on calendula plant. For essential oil percentage, the relationship between the main and subplot treatments was substantial in both cuts during both seasons.…”

To examine the ability of potassium humate (0, 1000, 2000 and 3000 ppm) for lessening the deleterious impacts of saline water (0, 1.4, 2.8 and 4.2 dS/m) on Rosmarinus officinalis plant, a pot study was undertaken at the Nursery of Ornamental Plants, Fac. Agric., Minia Univ. during the two experimental seasons 2022 and 2023. Data showed that all examined traits of vegetation development (plant height, branches number/plant, and herb fresh and dry weights) were decreased by increasing salinity levels (2.8 and 4.2 dS/m) compared with control in both cuts during both seasons. Opposite trend was obtained with the low concentration (1.4 dS/m). It was found that, while the essential oil (%) and its yield/plant were increased under (1.4 and 2.8 dS/m), the essential oil (%) and yield were significantly decreased under (4.2 dS/m) in both cuts during both seasons. The pigments content and NPK (%) took the same trend of the vegetative growth. While both Na (%) and proline content (µg/g) in dry leaves were increased by increasing salinity levels during the second cut in both seasons. All of the aforementioned characteristics of vegetation development, essential oil output and some chemical compositions were significantly improved by potassium humate treatments, with the exception of Na% and proline content (µg/g) over both seasons. In this concern, 3000 ppm potassium humate was the most effective treatment. There was a notable interaction impact between the two parameters under investigation for all examined parameters, with the best interaction treatment recorded with 1.4 dS/m in combination with potassium humate (3000 ppm). In conclusion, the negative effects of salinity stress may be mitigated by spraying plants with 3000 ppm of potassium humate.

“…It has been suggested that potassium humate is a workable and affordable solution for restoring damaged land resources. Additionally, studies by Said-Al Ahl et al (2009), Badran et al (2019), Shyala et al (2019), Wei et al (2021), and Shalaby et al (2023) have shown that potassium humate is a common organic fertilizer that may be improved.…”

In a trial to get an ideal growth of Hibiscus rosasinensis cv. Cooperi, a factorial pot experiment was carried out at the Botanical Garden of the National Gene Bank, Agricultural Research Center, Giza, Egypt during 2020 and 2021 seasons. Foliar spraying with both paclobutrazol (PBZ) at different levels (0, 50, 100 and 150 ppm) and two sources of potassium (K-sulfate at 1.5 and 3.0 g/l and K-humate at 2.0 and 4.0 g/l) and their interactions were applied. Vegetative growth, flowering parameters and some chemical constituents were evaluated. The results indicated that increasing PBZ level resulted in the lowest values for most studied parameters except PBZ at 100 ppm as recorded the highest values of number of leaves, branches and flowers/plant, vegetative growth fresh and dry weights, chlorophylls (a and b), carotenoids and indoles. Foliar spraying with two potassium sources was superior to control (without potassium foliar spraying) as recorded higher values. Integration of potassium foliar spraying reversed the undesirable effects of spraying with PBZ alone in particular at the high levels. The mastery was to PBZ at 100 ppm + K-humate at 2.0 g/l as recorded the highest values in most cases i.e. number of leaves, branches and flowers/plant, vegetative growth fresh and dry weights, chlorophylls (a and b), carotenoids and indoles. To produce high-quality Hibiscus rosa-sinensis cv. Cooperi pots, it is advised to treat the plants with PBZ at 100 ppm + K-humate at 2.0 g/l for 6 times at 2-week intervals.
