Chilli plants are considered as good nutrition source, which can be consumed by humans, animals, and used as a medicinal purpose. In non-sterile soil that included glucose and hydroxyapatite, the effects of phosphate-solubilizing bacteria (PSB) and vesicular-arbuscular mycorrhizae (VAM) on plant growth, soil microbial activity, and the synthesis of organic acids were examined. The tripartite interaction between PSB, mycorrhizal fungi and chilli crops are considered to be a beneficial effect on nutrient uptake of chilli crops, disease resistance and plant growth development. This process makes a secondary root system that improves nutrient status of the host plants, water absorption, growth and disease resistance and influencing mineral nutrients. Emerging advancements in improving precision Agriculture plays an important role in betterment of crops and their components. Dual inoculation of PSB and AM fungi leads to high yield of the crop and increase their nutrient concentration. This bacterial and fungal colonization alter the quality and abundance of the soil microflora and can modify the overall rhizosphere microbial activity. In this study, the combination of PSB and mycorrhizal fungi shows more benefits than their use alone in the chilli plants. On co-inoculation, they influence root system architecture and yield of plants. Treatments were made according to the co-inoculation and plant growth was analyzed in terms of their pod length, number of seeds per pod, number of pods per plants and yield. It has been concluded that application of Nitrogen and Phosphorus along with mycorrhiza and PSB was found to be most effective in comparison with other treatments.
