Manufacturing plant systems in South Africa have been identified as critical for agricultural productivity but are prone to operational risks. A randomized field trial was conducted across ten crop production facilities in South Africa. The trial included a control group and four intervention groups, each with different management strategies designed to mitigate risks such as pest infestations and water scarcity. Data collection involved regular monitoring for yield performance and operational efficiency. The analysis revealed that the intervention groups showed an average increase of 15% in crop yields compared to the control group (p < 0. 05, CI: 7%, 23%). The randomized field trial demonstrated the effectiveness of specific management interventions in reducing operational risks within South African manufacturing plant systems. Based on this study, it is recommended that all crop production facilities adopt the identified risk mitigation strategies to enhance their productivity and sustainability. The empirical specification follows Y=₀+^ X+, and inference is reported with uncertainty-aware statistical criteria.
