Abstract
The objective of this study was to evaluate the grain yield per unit of area of the corn-soybean intercropping in relation to their monoculture as a sustainable management alternative in the semiarid zone of Córdoba, Argentina. The Land Equivalent Ratio (LER), whose indifference value is 1, was 1.09 and 1.11 in the first and second essay, respectively. The intercropped corn was benefited in both experiences, while the intercropped soybean had a more indifferent behavior. The experimental evidence suggests that intercropping corn-soybean is a potential technology for the design of more sustainable systems, as it allows for an increase in grain yield per unit of area without additional agronomical inputs.
