Optimizing Rice Crop Manager Odisha: AI-Driven Yield Prediction to compliment Extension using legacy data

Rice cultivation (Oryza sativa) requires precise crop and soil management, making optimized nutrient recommendations essential for improving productivity. To address this, the Rice Crop Manager (RCM)—a web-based tool developed by the International Rice Research Institute (IRRI)—was deployed to assist farmers in making data-driven decisions. RCM collects farmer input data to generate tailored recommendations on planting schedules, irrigation, and weed control. Since its inception in 2015 in Odisha, India, it has provided over 300,000 recommendations across 31 districts, offering valuable insights into varietal preferences, agricultural trends, and socio-demographic patterns. To leverage legacy data effectively, machine learning algorithms have been integrated into RCM to identify key factors influencing crop outcomes and assist in estimating target yields. These models are extensively trained to predict yield and evaluate performance using metrics such as R², root mean square error (RMSE), and mean absolute error (MAE). The insights generated through RCM not only highlight the most widely grown rice varieties and annual sowing trends but also explore critical dimensions such as gender roles and youth participation in agriculture. Future expansions of RCM aim to enhance farmer engagement through chatbot development, enabling real-time interaction and decision-making support. Additionally, the system's architecture facilitates automated, data-driven recommendations, benefiting multiple stakeholders and contributing to greater agricultural productivity.
