The #Crop #Diversity #Experiment funded by @snf_ch can show first results available on @biorxivpreprint. First year results from #Switzerland show 21% and 44% increases in yield in 2- and 4-species #mixtures, respectively. Yield benefits in Spain were 3% and 13%. (1/5) 
In a first study we can show that these yield benefits of #intercropping are not due to reduced #weed pressure. Weed abundance was related to crop yield, but not affected by crop #richness, but rather by the presence of #cereals (2/)

A second study shows that increased crop yield in mixtures is both related to positive #sampling effects of tall species and positive #complementarity effects through more efficient #nitrogen use
