Objective: The objective of the study is to estimate the efficiency of nitrogen from the urea source applied as top dressing by root absorption and dissolved in water by foliar absorption on oat productivity indicators from the perspective of satisfactory productivity, with reduced costs and environmental impacts. Theoretical Framework: The nitrogen is a mobile element, easily absorbed and transported within plant tissues, studies indicate the potential for its application through foliar absorption Method: The study was conducted, in Augusto Pestana, RS, Brazil. The experimental design was randomized blocks with four replications in a 2x7 factorial scheme, for the two urea application sources (solid and dissolved) and seven nitrogen rates (0, 20, 40, 60, 80, 100 and 120 kg ha⁻¹), in a soybean/oat and corn/oat system. Results and Discussion: The supply of nitrogen by urea dissolved in water by foliar absorption presents results similar to solid urea from root absorption. The results, considering economic values, demonstrate a significant reduction in nitrogen use with productivity similar to maximum technical efficiency. Research Implications: This study contributes to more sustainable management practices in the use of nitrogen, reducing environmental impacts. Originality/Value: This study makes a great contribution for farmers, technical assistance agents and the food industry, improving the efficiency of production systems in guaranteeing food security and care for the environment and society.
