The study was conducted during 2024-25 at the Agricultural Research Farm, Maharishi School of Science and Humanities, Lucknow, Uttar Pradesh, to evaluate the impact of Nano urea and different levels of recommended dose of fertilizers (RDF) on wheat. Results revealed that the application of 100% RDF + 4 ml/L Nano urea (two sprays at jointing and panicle initiation stages) significantly improved growth, yield attributes, and grain yield compared to other treatments. This treatment (T₄) showed the highest initial and final plant population, 1000 grain weight, grains per spike, and grain yield (q/ha), followed by 100% RDF + 4 ml/L Nano urea (one spray at panicle initiation), and 75% RDF + 4 ml/L Nano urea (three sprays at CRI, jointing, and panicle initiation). The control group consistently recorded the lowest values across all parameters. The findings indicate that Nano urea, when applied with full RDF at critical growth stages, enhances wheat performance significantly in terms of both growth and productivity.
