“…were positively affected by chitosan application. Furthermore, Nofal et al (2021) proved the stimulative effect of chitosan application on Catharanthus roseus plants as compared to the other bio-stimulants. Humates are natural organic substances, high in humic acid and containing most of the known trace minerals necessary for plant growth and production.…”

Our study aimed to test the promoting effect of chitosan at rates100, 300 and 500 mg l -1 and humic acid at rates 100, 500 and 700 mg l -1 as a foliar application on Gomphrena globosa L. plus control plants sprayed with distilled water during 2022 and 2023 seasons. The obtained results cleared that the plants that received foliar application of chitosan at 300 mg l -1 showed the highest plant height value, Number of leaves, number of branches per, root length, shoot and root (fresh and dry weights). Moreover, the application of humic acid at a rate of 700 mg l -1 raised all the flowering traits including number of inflorescences, inflorescence diameter, inflorescence length, and inflorescences (fresh and dry weights). Furthermore, it was found that the most of chemical compositions including photosynthetic pigments, total sugars, flavonoids content in leaves, and betalain in inflorescences were increased in plants treated with chitosan 300 mg l -1 except total phenols content in leaves which showed the highest values in plants sprayed with humic acid at 700 mg l -1 .

“…The treatment of 30.0 mg l -1 of Humic acid was successful in promoting plant germination and was effective in germination of the species. Catharanthus roseus L. was the subject of a research by Nofal et al in 2021. The acquired findings demonstrated that, when compared to control treatment, the applied bio-stimulants considerably enhanced all growth and root parameters as well as their fresh and dry weights. Additionally, the chemical components of chlorophyll a and b, as well as their N, P, and K% and total alkaloids, increased in the leaves.…”

This search was conducted to investigate the impact of Humic acid (H.A.) fertilizer (0.0,10.0,20.0 and 30. 0 g l -1 ) and different media (100% peat moss , 50% peat moss + 50% perlite and 50% peat moss + 50% sand) and their combinations' effect on rooting and growth of Dracaena marginata under greenhouse conditions at the Nursery, Department of Floriculture, Ornamental Horticulture and Landscape Gardening, Faculty of Agriculture, Alexandria University, Egypt during the growing seasons 2021 and 2022. The results showed that terminal cuttings pretreated with H.A. combined with media had significant effects on survival %, rooting %, roots number /cutting, root length (cm), root fresh and dry weight (g). The highest significant values of rooting and growth obtained when Dracaena cuttings cultured in medium composed of 50% peat moss + 50% perlite combined with Humic acid (H.A) at 30.0 gm l -1 concentration. As well as, the highest significant results for total carbohydrates and total leaf chlorophyll content (a + b) were obtained after applying the aforementioned treatments. Chemical analysis also indicated that N, P and K content were markedly increased as H.A. concentrations increased up to 30.0 gml-1 with the growing media of peat moss 50% + perlite 50%. Dracaena cuttings in control treatment (without H.A.) grown in 100% peat moss recorded the lowest significant mean values for all characteristics under study in both seasons. Therefore, it is suggested that growing high-quality Dracaena plants for various aesthetic reasons be performed by treating Dracaena cuttings with H.A. at 20.0 or 30.0 gml-1 and cultivating in a mixture of 50% peat moss + 50% perlite.

This study seeks to analyze the complex interactions between color psychology, lighting technology, and the cultivation of Tsitsirika (Catharanthus roseus) in the Philippine agricultural environment. The study is organized around three main goals: first, to investigate the effect of several LED wavelengths, specifically red, blue, and green, on the overall growth parameters of Tsitsirika. Second, it intends to conduct a rigorous comparative analysis, carefully comparing the development patterns shown by various colored LEDs to those detected in natural solar irradiation. This comprehensive analysis seeks to identify significant differences and explain potential benefits or drawbacks related with the use of artificial lighting. Ultimately, the study aims to explain the physiological characteristics induced by red, blue, and green LED wavelengths on Tsitsirika, revealing their subtle effects on the plant's physiological and morphological aspects, including leaf pigmentation and stomatal behavior. By thoroughly addressing these objectives, this study hopes to provide nuanced and academically valuable insights on the prudent application of color psychology and lighting technology, ultimately influencing optimal cultivation practices for Tsitsirika. This scholarly endeavor is positioned to support sustainable and efficient agricultural practices, not just in the Philippines but also with potential for broader application.
