Nutrient deficiency in chilli plants significantly impacts growth, yield, and seed quality. To address this, a laboratory experiment was conducted during the Rabi season of 2022-23 at PJTSAU, Hyderabad using nutrient-doped carbon nanodots (CNDs). Seventeen treatments, including various concentrations of Zn, Fe, Cu, Mn, Ca, and B, were evaluated. Results revealed that iron-doped (T4) and manganese-doped (T8) carbon nanodot treatments significantly improved germination (up to 6% higher) and reduced abnormalities (by up to 5%), while higher doses of calcium (T11) and boron (T14) showed lower efficacy. These findings suggest the potential of nutrient-doped CNDs as innovative seed treatment agents to enhance seed quality and germination in chilli.
