Assessing the effect of split and additional late N fertilisation on N economy of maize
(Elsevier, 2024-03)Context: In the temperate-humid region of Argentina, nitrogen (N) fertilisers in maize (Zea mays L.) are mainly applied around sowing, whereas N-splitting is rare and occurs during early vegetative stages. Splitting and ... -
Canopy indices to quantify the economic optimum nitrogen rate in processing potato
(Springer, 2016-06)In-season N applications to processing potato crops may increase profits and improve N fertilizer use efficiency. The objective of our study was to evaluate indices to predict the differential economic optimum N rate (dEONR) ... -
Critical nitrogen dilution curve for processing potato in Argentinean Humid Pampas
(Springer, 2012-04)For processing potato, a new algorithm has been developed to determine nitrogen (N) requirement (NR) applying critical N dilution curve (Nc). The objectives of this work were i) to determine the Nc for processing potato ... -
Critical nitrogen dilution curve in processing potato cultivars
(Scientific Research, 2015-12)The critical nitrogen dilution curve (CNDC) can be used as a diagnostic tool to assess crop N nutrition during the growing season. Potato cultivars have different biomass production and accumulation of N and consequently ... -
Fertilización combinada con N-P-S-Zn en avena, cebada y trigo
(Asociación Argentina de la Ciencia del Suelo, 2023-12)En Argentina, nitrógeno (N) y fósforo (P) y recientemente azufre (S) y cinc (Zn) son nutrientes reconocidos como limitantes de la producción de los cereales de invierno. Las decisiones de manejo de la fertilización en avena ... -
Revisiting the relationship between nitrogen nutrition index and yield across major species
(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 ... -
Use of a critical phosphorus dilution curve to improve potato crop nutritional management
(Springer, 2016-08)Plant diagnostic methods to determine P deficiencies need the definition of a critical concentration value which represents the minimum P concentration required to achieve maximum growth. The critical P concentration (Pc) ...
