Abstract
The goal of the field experiment, which took place in 2020–21 at the Instructional Farm, Department of Fruit Science, College of Horticulture and Forestry, Jhalawar (AU Kota), was to investigate the physical–chemical properties of soil in the rhizosphere of guava (Psidium guajava L.) cv. Sardar, as well as the singular and synergistic impact of bio-stimulants. Nineteen treatments were analysed in a randomised block design with three replications, including three bio-stimulants applied through soil drenching: silicon, seaweed and humic acid. The results of the study showed that the application of bio-stimulants, specifically T12 (humic acid 15 g + seaweed 60 g), greatly improved the pH, electrical conductivity, organic carbon content and nutrient availability of the soil. In addition, microbial populations within the rhizosphere demonstrated a significant increase, particularly in favourable weather circumstances. These results highlight the ability of bio-stimulants to improve plant development and soil health in guava plantations. Comprehending the complex interplay between soil parameters and bio-stimulants might provide valuable insights for sustainable farming methods that aim to optimize yield while reducing ecological footprint. To further understand the long-term impacts and underlying mechanisms of bio-stimulants mediated changes in soil fertility and microbial activity, more study in this field is necessary.
