Abstract
Maize (Zea mays L.) is a crucial global crop, vital for food security and diverse applications. Maize cultivation heavily depends on fertilizers, particularly nitrogen-based ones and their widespread use poses risks like nutrient runoff, causing pollution and economic challenges.
 Balancing growth optimization with environmental/economic considerations requires optimizing fertilizer application and sustainable practices. This study aims to reduce reliance on chemical fertilizers by replacing them with microbial-enriched urban compost and wastes in various combinations with inorganic fertilizers to enhance maize yields.
 A treatment incorporating 75% NPK + 7.5 t ha-1 of microbial-enriched urban solid waste compost demonstrated the highest plant height, leaf count, cob length, kernel yield, and stover yield. The combined use of enriched compost and chemical fertilizers resulted in increased nutrient availability, improved soil properties, and a favorable microbial environment, contributing to enhanced overall yield.
