Soybean intercropped with sunflower is an efficient solution to increase global grain production in low input systems
Abstract
Intercropping (IC) could be efficient and lead to eco - functional intensification. The main objective was to evaluate the potential advantages of soybean - sunflower IC for global grain yield. Based on recent experiments, we demontrated that the LER could be significantly higher than 1 when the cover pattern is adapted, i.e. for 2 sunflower rows combined with 4 soybean rows pattern (LER = 1 . 2 ). Finally, we confirm that IC is efficient only in low input systems, even for summer crops.
