    • A practical guide to estimating the light extinction coefficient with nonlinear models—a case study on maize 

      Lacasa, Josefina; Hefley, Trevor J.; Otegui, María Elena; Ciampitti, Ignacio A. (Springer Nature, 2021-06-12)
      The fraction of intercepted photosynthetically active radiation (fPARi) is typically described with a non-linear function of leaf area index (LAI) and k, the light extinction coefficient. The parameter k is used to make ...

    • Breeding effects on canopy light attenuation in maize: a retrospective and prospective analysis 

      Lacasa, Josefina; Ciampitti, Ignacio A.; Amas, Juan Ignacio; Curín, Facundo; Luque, Sergio F.; Otegui, María Elena (Oxford University Press, 2022-03)
      The light attenuation process within a plant canopy defines energy capture and vertical distribution of light and nitrogen (N). The vertical light distribution can be quantitatively described with the extinction coefficient ...

    • Revisiting the relationship between nitrogen nutrition index and yield across major species 

      Rodriguez, Ignacio; Lacasa, Josefina; van Versendaal, Emmanuela; Lemaire, Gilles; Belanger, Gilles; Jégo, Guillaume; Sandaña, Patricio; Soratto, Rogério; Djalovic, Ivica; Ata-Ul-Karim, Syed Tahir; Reussi Calvo, Nahuel Ignacio; Giletto, Claudia Marcela; Zhao, Ben; Ciampitti, Ignacio (Elsevier, 2024-03)
      Crop nitrogen (N) fertilization diagnoses via the N nutrition index (NNI)-yield relationship have been tested for several crop species, but a cross-species comparison of that relationship has not been performed yet. This ...
