This study investigated the production process and effectiveness of an organic fertilizer derived from carbonized rice husk and vermicompost. This study adopts a Randomized Complete Block Design (RCBD) to evaluate the effects of different treatments of carbonized rice husk and vermicompost on soil fertility, crop yield, and economic outcomes. The experiment was conducted both in controlled conditions (greenhouse) and in field trials to ensure comprehensive results. The research focused on the step-by-step method of production, its environmental sustainability, and its potential to improve soil health and boost agricultural productivity. The research explored the economic feasibility and its impact on household food security in the production of Maize (Zea mays) in the study area. Households using carbonized rice husk and vermicompost reported increased access to nutritious food, which improved their food security index by an average of 30%. Soil fertility improved most significantly under CRH+VC, indicating synergistic effects. Conclusively, the study recommends that categorized, practical, and prioritized steps in the Production and Application of Carbonized Rice Husk (CRH) and Vermicompost as sustainable inputs to improve soil fertility and household food security in Nigeria.
