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 ... -
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 ... -
The allometric relationships between biomass and nitrogen of vegetative organs affect crop N status in maize at silking stage
Maltese, Nicolás; Maddonni, Gustavo Angel; Melchiori, Ricardo Jose; Ciampitti, Ignacio A.; Caviglia, Octavio (Elsevier, 2023-04)In maize (Zea mays, L.) changes in the partitioning of biomass (W) and nitrogen (N) between organs linked to photosynthetically active tissues, such as leaves (with high N concentration, %N) and organs related to supporting ...
