The sustainable farming practices aimed at optimizing bush bean production in the Nilgiris Biosphere, addressing the challenges posed by tropospheric ozone and promoting ecological resilience.The problem is to identify effective sustainable farming practices that can enhance bush bean production in the Nilgiris Biosphere while mitigating the adverse effects of tropospheric ozone pollution.The objective is to evaluate and implement sustainable farming practices that optimize bush bean production in the Nilgiris Biosphere while reducing the impact of tropospheric ozone. To identify strategies that enhance crop resilience and productivity. A randomized block design was employed, testing various practices including organic fertilization, cover cropping, crop rotation, Integrated Pest Management (IPM), and reduced tillage. Key parameters assessed included plant height, pod yield, soil quality, and pest incidence. Results indicated that organic fertilization led to a 25% increase in pod yield, while cover cropping improved soil moisture retention, and yielding. The findings revealed that these sustainable methods mitigated the oxidative stress effects caused by tropospheric ozone, enhancing the plant’s ability to thrive in challenging conditions. This research highlights the importance of integrating sustainable agricultural practices to optimize bush bean production in sensitive ecosystems. The study not only provides evidence of increased yields and improved soil quality but also emphasizes the role of these practices in fostering ecological balance and resilience against environmental stressors. The outcomes support the need for policy initiatives and farmer education programs focused on promoting sustainable agriculture in the Nilgiris Biosphere, ensuring both economic viability for farmers and environmental sustainability.The future scope includes scaling successful sustainable practices to other crops and regions, integrating advanced technologies for monitoring ozone impacts, and promoting farmer education to enhance resilience against environmental challenges.
