Optimizing Seed Germination and Enhancing Seedling Vigor in Soybean through Humic Acid and Triacontanol Applications: A Comprehensive Study

The growth and production of plants are largely determined by the stages of seed germination through seedling development. To promote the development and growth of plants, the use of natural substances has attracted a lot of interest recently, however, little is known about how they specifically affect soybean (Glycine max) seed development and subsequent seedling growth. This study was executed to assess how humic acid (HA) and triacontanol (TRIA) affected the germination and growth of soybean seeds. The experiment was divided into two phases; a laboratory trial measuring germination and associated variables, and a field trial examining seedling vigor Maintaining a control group (T0) and three treatment groups (T1 for humic acid, T2 for triacontanol, and T3 for both humic acid and triacontanol). Humic acid as well as triacontanol treatments (Humic acid (5g/L) + Triacontanol (0.6 ml/L) had a favorable impact on the germination rates, leaf characteristics, and root morphology of soybean seeds. The best germination rates and earliest seedling development were consistently seen in treatment T3. T2 showed very modest gains, whereas T1 exhibited favorable impacts on leaf development. These results point to the advantages of utilizing these plant growth enhancers in soybean farming. To maximize their impacts on soybean production, more study is required to investigate the underlying processes and to improve the dose and application techniques.
