Wheat (Triticum aestivum L.) production is vital for India's food security, with projections indicating a substantial 70-104 % increase in demand by 2050. However, Eastern Plateau regions face challenges of warmer climate leading to aberration irrigation regimes (IRs) and nutrient, especially nitrogen (N) management resulting lower productivity. Study revealed that IRs significantly influenced yield attributes viz., spikelets/spike 1000-grain weight, moisture stress during grain filling stages adversely impacting development, resulted 29 reduction. The 100 recommended dose (RDN) superior attributes; surpassing nano-urea based application. RDN the highest N content 7.0 14.5 more compared 50 RDN+2 NUS (nano-urea spray) treatment respectively. Interaction effect 3-irrigation on was over nullifying synergistic IRs. reported (p=0.05) (0.42 %) uptake (31.30 kg/ha) straw. Additionally, five irrigations exhibited higher total 30.9 25.78 two irrigations, Apparent recovery agronomic use efficiency were due better acquisition less amount application through NUS. Thus can be as an practice maximising wheat productivity region India.
