Integrated nutrient matrices optimise wheat productivity and edaphic health while mitigating the ecological footprint of intensive fertilisation. Nano-fertilisers, specifically Nano-Urea, represent a frontier in agricultural engineering. By leveraging a high surface-to-volume ratio, nanoscale nutrients bypass traditional soil-bound loss pathways through direct foliar penetration and controlled metabolic release. The present study explores the synergistic impact of integrated nutrient matrices and Nano-Urea on wheat productivity and pedological resilience in a semi-arid/subtropical zone during the wet season. A field experiment was conducted during the 2024–25 Rabi season at KVK, Ghazipur, India using a randomised block design with three replications. The study evaluated nine nutrient management strategies in the wheat variety DBW-187 (Karan Vandana). Treatments integrated the Recommended Dose of Fertiliser (RDF: 150:60:40 kg ha⁻¹) with organic amendments (FYM @ 5 t ha⁻¹) and precision nanotechnology (Nano-Urea foliar sprays). Key physiological indices—Leaf Area Duration (LAD), Chlorophyll (SPAD), and protein biosynthesis—were monitored alongside post-harvest pedological properties and resource use efficiency metrics such as Partial Factor Productivity (PFP). Treatment T4 (100% RDF + FYM) achieved the highest grain yield (6.20 t ha⁻¹) and maximum LAD (175.6 days), followed closely by T6 (100% RDF + Nano-Urea). Nano-Urea application significantly elevated grain protein to 10.2% and physiological efficiency to 38.4 by bypassing traditional nitrogen loss pathways. Integrated regimes also ameliorated soil architecture, reducing bulk density to 1.42 g/cc and augmenting soil organic carbon to 0.52%. These synergies align nutrient flux with crop ontogenetic demand, maximising metabolic assimilation and environmental stewardship. Integrated management using FYM and Nano-Urea optimises wheat yields, protein quality, and soil resilience.
