Leguminous crop Tephrosia candida has high biomass production and contains a substantial quantity of nutrients within its biomass. Starting in 2019, a long-term study was done to find the best Tephrosia candida dose for mulching in guava orchards. The study had four treatments: T<sub>1</sub> = 3.0 kg dry biomass m<sup>-2</sup> of the plant basin, T<sub>2</sub> = 2.0 kg, T<sub>3</sub> = 1.0 kg, and T<sub>4</sub> = control (no mulch). Every year, the treatments imposed in the month of August. The third year (2021-2022) results indicated that mulching with 3 kg of biomass m<sup>-2</sup> increased trunk diameter, fruit yield, fruit weight, specific leaf area, total leaf chlorophyll, and leaf macro- and micro-nutrients. At 3.0 kg m<sup>-2</sup>, mulching improved soil properties such as EC, available nitrogen, available phosphorus, exchangeable potassium, DTPA extractable micronutrients (Fe, Zn, Cu, and Mn), total organic carbon (C<sub>toc</sub>), soil organic carbon (C<sub>soc</sub>), organic carbon fractions, and microbial biomass carbon between 0-0.15 m and 0.15-0.30 m. There was an increasing trend in dehydrogenase activity (DHA) and fluorescein diacetate (FDA). The Tephrosia leaf litter exhibited decay constants of 1.27 year<sup>-1</sup>, and the carbon content was 40.11%. Therefore, applying Tephrosia biomass mulching at a rate of 3.0 kg m<sup>-2</sup> is a viable long-term solution for enhancing soil fertility and sequestering carbon.
