Abstract
One of the key challenges today is ensuring food security for the growing global population. To achieve this, the efficient and environmentally sustainable use of mineral fertilizers in agricultural crops is essential for obtaining high-quality yields. This study examines the effects of urea application at different growth stages — 4.0 kg/ha during tillering, 8.0 kg/ha during tuber formation, 12.0 kg/ha during spiking, and 16.0 kg/ha during milk-wax ripening — on crop productivity. The results demonstrate that the use of diluted urea suspensions significantly improves grain yield by enhancing leaf surface area and overall plant growth.
