      Nitrogen (N) is the quantitatively most important nutrient in cropping systems. The use of nitrate as a mineral fertilizer is highly energy-intensive and causes greenhouse gas emission and groundwater pollution. Therefore, the need to reduce N-fertilizer input is pressing. In order to compensate that reduction, new crop genotypes must be sought with improved nitrogen use efficiency (NUE). While ...

    • In-Field Observation of Root Growth and Nitrogen Uptake Efficency of Winter Oilseed RapePeer reviewedOpen access

      Article scientifique
      Field trials were conducted with two nitrogen applications (0 or 240 kg N ha−1) and three modern cultivars of winter oilseed rape (Brassica napus L.) previously selected from a root morphology screen at a young developmental stage. The purpose is to examine the relationship between root morphology and Nitrogen Uptake Efficiency (NUpE) and to test the predictiveness of some canopy optical indices for ...

    • Oilseed Rape Cultivars Show Diversity of Root Morphologies with the Potential for Better Capture of NitrogenPeer reviewedOpen access 

      14 décembre 2021, Kupcsik, László; Chiodi, Claudia; Moturu, Taraka; De Gernier, Hugues; Haelterman, Loïc; LOUVIEAUX, Julien; Tillard, Pascal; Sturrock, Craig J.; Bennett, Malcolm; Nacry, Philippe; Hermans, Christian, HE Condorcet
      Article scientifique
      The worldwide demand for vegetable oils is rising. Oilseed rape (Brassica napus) diversifies cereal dominated crop rotations but requires important nitrogen input. Yet, the root organ is offering an untapped opportunity to improve the nitrogen capture in soil. This study evaluates three culture systems in controlled environment, to observe root morphology and to identify root attributes for superior ...

    • Root Morphological Traits of Seedlings Are Predictors of Seed Yield and Quality in Winter Oilseed Rape Hybrid CultivarsPeer reviewedOpen access 

      15 octobre 2020, LOUVIEAUX, Julien; SPANOGHE, Martin; Hermans, Christian, HE CondorcetCARAH
      Article scientifique
      The root system is responsible for soil resources acquisition. Hence, optimizing crop root characteristics has considerable implications for agricultural production. This study evaluated a panel of twenty-eight European modern cultivars of oilseed rape (Brassica napus L.) cultivated in laboratory and field environments. Root morphology was screened using a high-throughput hydroponic growth system ...
