Abstract

The study sought to assess the effect of various bioinoculants on the growth and biochemical features of Senna alexandrina or Cassia aungustifolia, a medicinal plant recognized for its laxative qualities. The study looked at how nitrogen-fixing bacteria, phosphate-solubilizing microorganisms, and PGPR affect plant development and biochemical properties, both separately and in combination. It measured shoot and root development, chlorophyll concentration, total proteins, and enzymatic activity. The findings shed light on how bioinoculants improve plant performance. Senna alexandrina was exposed to both single and combined applications of bioinoculants, such as PGPR, phosphate-solubilizing microorganisms, and nitrogen-fixing bacteria. Plant height, number of leaves, biomass, and root length were among the growth metrics that were noted. The amount of chlorophyll, total soluble proteins, and enzymatic activity (catalase and peroxidase) were measured using biochemical techniques. According to the study, Azospirillum considerably improved Senna alexandrina's development and biochemical characteristics. Plants treated with T4 exhibited the longest shoot (54.92 cm) and the most leaves, while other treatments showed a notable increase in root length between 30 and 90 days. T4 plants had the highest levels of reducing sugars and total chlorophyll, followed by T3 and T2, while T2, T3, and T4 plants also had significantly higher protein content in their roots than T1 plants. These results demonstrate Azospirillum's capacity to enhance Senna alexandrina's development and biochemical characteristics. The study emphasises the potential of bioinoculants as sustainable and environmentally friendly methods of enhancing Senna alexandrina agriculture and medicinal benefits. These results help sustainable agriculture and the rising demand for herbal goods by providing important information for creating bioinoculant-based methods to improve the production of medicinal plants

Conclusion

Azospirillum has the ability to fix molecular nitrogen, which increases soil fertility and promotes plant development. Azospirillum is frequently used in agriculture, particularly in nitrogen-based fertilizers using crops. We concluded that Azospirillum had and PSB a considerable effect on Cassia angustifolia instead of Senna alexandrina's root, shoot and leaf growth. Furthermore, Azospirillum and PSB had a significant effect on Senna's carbohydrate and protein content. At the 5% level of significance, chlorophyll-a, chlorophyll-b, and total chlorophyll concentration differed significantly between treatments and over different days of a given treatment
