    • Crop nitrogen status of early- and late-sown maize at different plant densities 

      Maltese, Nicolás; Maddonni, Gustavo Angel; Melchiori, Ricardo Jose; Ferreyra, Juan Matías; Caviglia, Octavio (Elsevier, 2020)
      In maize (Zea mays L.) crops, nitrogen (N) status at silking (R1) has been used to predict grain yield (GY) response to N fertilization and to develop strategies to manage crop nutrition in order to match N supply with ...

    • Nitrogen economy of early and late-sown maize crops 

      Maltese, Nicolás; Melchiori, Ricardo Jose; Maddonni, Gustavo Angel; Ferreyra, J.M.; Caviglia, Octavio (Elsevier, 2018-11)
      Late sowing dates of maize are widely adopted in the Pampas region of Argentina, stabilising grain yields due to a more favourable water balance around flowering. However, late-sown crops are exposed to high soil N ...

    • Nitrogen utilization efficiency in maize as affected by hybrid and N rate in late-sown crops 

      Caviglia, Octavio; Melchiori, Ricardo Jose; Sadras, Victor Oscar (2014-11)
      After the introduction of Bt-maize, late sowing is becoming an important strategy to stabilize yields in many areas of the Argentine Pampas. Increased nitrogen (N) availability and sharp reduction in radiation and temperature ...

    • Plant nitrogen status at flowering and kernel set efficiency in early- and late-sown maize crops 

      Maltese, Nicolás; Maddonni, Gustavo Angel; Melchiori, Ricardo Jose; Caviglia, Octavio (Elsevier, 2021-08)
      In maize (Zea mays, L.) genotypic variability in the relationship between total kernel number per plant (KNP) and plant growth rate (PGR) during the period bracketing silking (R1 ± 15 d), and in kernel set efficiency (KNP ...
