Abstract
Abstract The economic and environmental performances of agriculture intercropping depend on the complementarities between the crops that make up the system. The objective of this work was to analyze the citrus-based intercropping systems in the Coastal Tablelands region of Northeastern Brazil, aiming to identify the associations of crops with better economic and environmental performances. The study started with the construction of a set of integrated indicators, with which the field information was recorded and the performance indices calculated, based on three principles: Profitability, Productive Efficiency, and Biological Regulation. Citrus orchards in monoculture resulted in lower environmental economic performance indices. The intercropping systems that yielded the best environmental and economic performance indices in the citrus orchards were: cassava; cassava, corn and beans; corn and pumpkin. The indicators associated with these economic-environmental performances were profit, seasonality, productive diversity, profit evenness, plant health control impact level, and efficiency in the use of water, nitrogen, and phosphate.
