An experiment was conducted at the Agronomy Research Farm of Acharya Narendra Deva University of Agriculture and Technology in Kumarganj, Ayodhya, Uttar Pradesh, India, during the Kharif seasons of 2022 and 2023. The study aimed to evaluate the effects of planting geometry and inorganic fertilizers, combined with nano urea, on soil health parameters and quality of rice crop. The experiment utilized a split plot design with three replications, incorporating three planting geometries—C1 (20 cm × 10 cm), C2 (20 cm × 15 cm), and C3 (20 cm × 20 cm) in the main plot. The subplot treatments included five fertilizer levels: F1 (100% RDF (150:60:40)), F2 (100% RDF + two foliar sprays of nano urea at 3000 ml ha⁻¹ during the Tillering and Panicle Initiation stages), F3 (75% RDF + two foliar sprays of nano urea), F4 (50% RDF + two foliar sprays of nano urea), and F5 (Control with no fertilizers). Results showed that the combination of treatment C1 (20 cm × 10 cm) with F2 (100% RDF + two foliar sprays of nano urea at 3000 ml ha⁻¹ during the Tillering and Panicle Initiation stages) was optimal for enhancing the soil health and quality of rice grain, resulting in maximum yield attributes and yield (q ha-1) of rice across both years of the study.
