Root growth potential was assessed in a separate trial under controlled conditions. Rank of varieties regarding N-uptake was dependent on yield level of the test environments and was mainly due to differences in uptake during grain filling. In one variety high N uptake potential coincided with high root growth in later growth stages. kassel university press GmbH, Kassel Heß, J Rahmann, G 2005 Conference paper, poster, etc. NonPeerReviewed application/pdf http://orgprints.org/3763/1/3763.pdf Baresel, J P; Reents, H J and Zimmermann, G (2005) Sortenbedingte Unterschiede der N-Effizienz und Beziehung zum Wurzelwachstums von Weizen (Triticum aestivum L.) unter den Bedingungen des Ökologischen Landbaus.
