Abstract: Pearl millet (Pennisetum glaucum L.), a crucial crop for arid regions, was studied to evaluate the effects of conventional and nano urea on its quality and nutrient content and uptake. Experiment conducted at the B.A. College of Agriculture, Anand Agricultural University, Anand, Gujarat, India, in 2022-2023, experiment used Randomized Block Design with twelve treatments replicated thrice. Treatments varied between conventional urea and foliar sprays of liquid nano urea at different concentrations. Results indicated that applying 100% RDN through urea combined with a foliar spray of 4 mL/L liquid nano urea (T₁₀) significantly increased crude protein content (11.81%), nitrogen content and uptake in both grain and straw compared to other treatments. Although phosphorus and potassium content in plants were unaffected by treatments, their uptake was significantly higher in T₁₀. These enhancements are attributed to the unique properties of nano-fertilizers, including improved penetration and nutrient use efficiency. The study highlights the potential of liquid nano urea to enhance pearl millet's nutrient profile, offering a sustainable solution for improving crop productivity in nitrogen-deficient soils. These findings are consistent with previous research in other crops, suggesting a broader applicability of nano-fertilizers in agriculture.
