<![CDATA[Corn productivity is heavily influenced by fertilization practices. Nanotechnology-enabled fertilizers offer controlled-release systems that enhance nutrient delivery efficiency while minimizing environmental losses, thereby reducing chemical fertilizer dependency. The research was conducted to evaluate of varying concentrations of Pornas nanotechnology liquid organic fertilizer on corn growth and yield. The experiment was conducted from January to November 2023 in Bangun Rejo Village, Tenggarong Seberang District, Kutai Kartanegara Regency, East Kalimantan, Indonesia, using a Randomized Complete Block Design with five replications. Treatments consisted of five Pornas concentrations (0.0, 0.5, 1.0, 1.5, and 2.0 mL L⁻¹. Data were analyzed using ANOVA and DMRT at a 5% significance level. Results showed that Pornas application significantly improved plant height, stem diameter, cob dimensions, kernel traits, and overall yield, but did not affect leaf number. The optimal concentration was 1.5 mL L⁻¹, which maximized yield at 5.07 Mg ha⁻¹ without significantly different from the 2.0 mL L⁻¹, indicating superior nutrient use efficiency. These findings demonstrate the potential of nano-liquid organic fertilizers for sustainable maize production in marginal tropical soils.]]>
