IntroductionDeveloping organic herbal crops provides chemical-free herbs to support environmentally friendly and sustainable farming. One way in agricultural biotechnology to grow herbal organic crops is to use rhizobacteria. The herbal plant used in this study is the Javanese ginseng plant (Talinum paniculatum), which contains phytochemicals that increase stamina.MethodsThe study used four rhizobacteria to enhance the growth and phytochemistry of T. paniculatum leaves; the target phytochemical compounds analyzed in Javanese ginseng leaves were total flavonoids, total phenols, and antioxidants (IC50%). The four selected rhizobacteria can produce indole-3-acetic acid (IAA), fix nitrogen, and dissolve phosphate. Thus, high-quality T. paniculatum leaves were obtained as herbal tea ingredients. The pattern used is a random group pattern in the greenhouse.ResultsThe results of the study showed that the use of rhizobacteria at 2% concentrations had a real effect on plant growth parameters such as plant height, leaf area, root length, wet weight and dry weight of the plant, and phytochemical content like total flavonoids, total phenols, IC50%, total chlorophyll, content of T. paniculatum leave plant when compared to the control. The four rhizobacteria used can produce the IAA, fix nitrogen, and dissolve phosphorus.DiscussionThe four rhizobacteria can also colonize the root of the T. paniculatum plant. The four Rhizobzcteria used significantly affected the growth and phytochemical content of T. paniculatum leaves as an ingredient in herbal tea at a concentration of 2% compared to controls. The four rhizobacteria can produce IAA hormones, fix nitrogen, and dissolve phosphorus. All four rhizobacteria can colonize the roots of T. paniculatum plants. These four rhizobacteria can be used as alternative methods in developing organic farming systems and can also be used practically in the field by farmers. It is necessary to research the application of rhizobacteria to other crops to support sustainable agriculture.

Sorghum bicolor, an important global crop, adapted to thrive in hotter and drier conditions than maize or rice, has deep roots that interact with a unique and stratified soil microbiome that plays a crucial role in plant health, growth, and carbon storage. Microbiome studies on agricultural soils, particularly fields growing S. bicolor, have been mostly limited to surface soils (<30 cm). Here we investigated the abiotic factors of soil properties, field location, depth, and the biotic factors of sorghum type across 38 genotypes on the soil microbiome. Utilizing 16S rRNA gene amplicon sequencing, our analysis reveals significant changes in microbial composition and decreasing diversity at increasing soil depths within S. bicolor regardless of genotype or fields. Notably, specific microbial families, such as Thermogemmatisporaceae and an unclassified family within the ABS-6 order, were enriched in deeper soil layers beyond 30 cm. Additionally, microbial richness and diversity declined with depth, reaching a minimum at the 60 - 90 cm layer, with layers beyond 90 cm increasing in alpha diversity. These findings highlight the importance of soil depth in agricultural soil microbiome studies.
