This study investigates the effects of several organic fertilizers on baby spinach (Spinacia oleracea L.) cultivation’s growth, productivity, and sustainability. A randomized complete block design was employed to assess six organic fertilizer treatments, including vermicompost, farm yard manure (FYM), poultry waste, Azotobacter + poultry waste + FYM, Azotobacter + vermicompost, and a control (no fertilizer application). Plant growthparameters, nutrient content, pest resistance, soil health indicators, and environmental implications were evaluated to understand the effectiveness of organic fertilizers in promoting sustainable spinach production. Results indicate that treatments incorporating Azotobacter inoculants, particularly those combined with poultry waste or vermicompost, demonstrated superior performance in terms of production, biomass accumulation, plant height, leaf area, and nutrient content. These findings underscore the potential of bioinoculants in organic farming to increase soil fertility and ecological resilience, decreasedependency on synthetic inputs, and increase crop output. Moreover, organic fertilizers significantly influenced soil health parameters, with treatments exhibiting higher soil pH, organic matter content, and microbial activity contributing to improved soil fertility. Environmental implications of organic fertilizer use were also assessed, revealing varyinglevels of nutrient runoff and greenhouse gas emissions across different treatments. While Azotobacter-inoculated treatments showed higher greenhouse gas emissions, they also exhibited greater nutrient retention, indicating complex trade-offs between nutrient cyclingand environmental impact
