This research study explores the economics of plant and soil health in potato cultivation, with a specific focus on two key aspects: the economic impact of Pectobacterium and Dickeya on potato crops in the first chapter and the impact of soil management practices on net returns in the second chapter. The first chapter examines the economic consequences of Pectobacterium and Dickeya, two pathogens affecting potato crops. By assessing the change in total revenue resulting from percentage of infection at planting, this study provides insights into the financial implications associated with these pathogens. The second chapter evaluates the impact of soil management practices on net returns in potato cultivation. By analyzing the economic outcomes of various soil management techniques, such as crop rotation, fumigation and manure application this study assesses their effects on potato yields and overall net returns. Understanding the economic implications of different soil management practices enables informed decision-making for farmers and policymakers, aiming to enhance the profitability and sustainability of potato production. By exploring the economic dimensions of Pectobacterium and Dickeya on potato crops and the impact of soil management practices on net returns, this research provides valuable insights for improving the economic viability of potato cultivation. These findings can inform farmers, researchers, and policymakers seeking to optimize their net returns while ensuring plant and soil health.

Keywords: economics, potato, disease management, crop rotation, net returns.
