  • Long-term effect of different tillage systems on the emergence and demography of Bromus diandrus in rainfed cereal fields 

    Recasens i Guinjuan, Jordi; García, Addy Laura; Cantero Martínez, Carlos; Torra Farré, Joel; Royo-Esnal, Aritz (European Weed Research Society, 2016)
    The adoption of no-tillage systems in semi-arid cereal fields in northern Europe has resulted in difficulties in controlling Bromus diandrus. However, in some fields, lower densities are observed in continuous long-term ...
  • Transdisciplinary weed research: new leverage on challenging weed problems? 

    Jordan, N.; Shut, M.; Graham, S; Barney, J. N.; Childs, D. Z.; Christensen, S; Cousens, R. D.; Davis, A. S.; Eizenberg, H.; Ervin, D. E.; Fernandez Quintanilla, C.; Harrison, L. J.; Harsch, M.
