Effect of nano urea on growth and yield of scented geranium (Pelargonium graveolens L. Herit)

Nanotechnology holds promise for optimizing nutrient delivery in agriculture. This study examines the impact of nano urea, a nanoscale urea formulation, on scented geranium (Pelargonium graveolens) growth and yield. A randomized controlled trial compared nano urea with traditional urea on various growth and yield parameters. Nano urea treatment, T7-15 kg N neem coated urea + 0.5 ml l-1 nano urea improved the growth and yield of scented geranium. Plants sprayed with nano urea had maximum growth (plant height, number of leaves per plant, number of branches per plant, plant spread), yield (fresh herbage yield (1.53 and 1.26 kg per plant, 28.76 and 25.56 kg per net plot and 14.27 and 12.68 t per hectare) and essential oil yield per hectare (14.70 and 13.11 kg) in both the main as well as ratoon crops respectively.
