The integration of agronomic practices has shown significant potential in enhancing maize yield and nutrient use efficiency (NUE). This study synthesizes findings from multiple studies to evaluate the impact of integrated agronomic practices (IAP) on maize yield and NUE under varying soil fertility conditions. Studies indicate that IAP, which includes optimal planting density, split fertilizer application, and subsoiling tillage, can substantially increase maize grain yield and NUE compared to traditional farmers' practices (FP). The combination of organic and inorganic fertilizers, as part of integrated nutrient management (INM), has also been shown to improve soil fertility and crop productivity, contributing to sustainable agricultural practices. Long-term field studies reveal that integrated soil-crop system management (ISSM) strategies can achieve high maize yields and NUE with reduced environmental costs. Additionally, the integration of weed and nutrient management practices has been found to enhance maize yield, nutrient uptake, and economic returns in rice-maize cropping systems. The application of biochar in conjunction with partial doses of inorganic fertilizers further supports improved crop productivity and sustainability in maize-wheat cropping systems. Overall, the adoption of integrated agronomic practices offers a promising approach to achieving higher maize yields and better nutrient use efficiency, thereby supporting sustainable agricultural intensification.
