The present study aims to analyze the impact of Precision Agriculture (PA) on food production in Brazil. We applied the multicriteria group decision using the Analytical Hierarchy Process (AHP) to weigh several selected criteria. The group consensus was very high (91.9%). The most critical criteria in level 1was the machinery input (48.9%), followed by software (44.4%) and human resources (6.7%). In level 2, within the machinery criterion, the sub-criteria soil was the most critical (31.9%), followed by pest control (28.5%). In level 2, within the software criterion, the sub-criteria input management was the most critical one (48.4%), followed by product management (42.3%). The four most significant global priorities are the sub-criteria soil (31.9%), Input management (21.5%), Product management (18.8%), and Pest control (13.9%). Results indicated that the use of PA in grain crops has a high impact on food production (71.1%).
