Field research stations in Ghana are pivotal for advancing agricultural knowledge and practices through systematic experimentation. A randomized controlled trial design was employed to assess SPIs, including yield per hectare, water usage efficiency, and pest infestation rates. Data collection spanned three growing seasons. Significantly higher yields were observed in the treatment group compared to the control (p < 0.05). The system's reliability was validated as robust under field conditions, with yield improvements attributed to optimised SPIs. Integrate SPI monitoring into routine management protocols and consider scaling up successful interventions.
