Abstract

Its excellent medical potential and widespread demand for its herbal products have led to indiscriminate exploitation and a severe risk of extinction. A durable and effective method has been created for both seed and semi-hard stem cutting propagation. Certain growth hormones have been applied at varying concentrations. At 10 mg/L (96.67%), catchin acid had the highest sprouting percentage, whereas tanic acid had the lowest at 2.5 mg/L (24.0%). In the second year, IBA 250 mg/L (85.33%) demonstrated statistically significant rooting (%) and root length/plant. IBA 250 mg/L, 13.67 cm, IBA + Phloroglucinol 250+10 mg/L, and Salicyclic acid 25 mg/L, 7.33. 250 mg/L (14.67 cm) were used to assess the average root length/plant in NAA. Seed germination rates obtained with NAA 500 mg/L (84.73%) and IBA 250 mg/L (85.74%) were statistically significant and showed similar levels of effectiveness. From 2005 to 2013, monthly measurements of the FYM doses—15, 30, 45, and 60 t/ha with control—were made and statistically examined annually. The purpose of the FYM x Spacing project was to look at the leaf producing industry’s economic feasibility. From 2009 to 2013, FYM 30 t/ha yielded the most leaves. This study focused on improving propagation techniques through semi-hard stem cuttings and hormone-guided seed germination. IBA showed superior performance in both rooting of cuttings and seed germination. Interestingly, a sizable percentage of sprouting and rooting was also induced by catchin and galic acid.
