Ability of in situ canopy spectroscopy to differentiate genotype by environment interaction in wheat
(Taylor & Francis, 2021-03)In recent years, the application of remote sensing techniques is gaining a growing interest and importance in agriculture. Researchers often combine data from near-infrared and red spectral bands according to their specific ... -
Aplicación de fósforo en secuencias agrícolas en siembra directa en hapludoles énticos = Phosphorus fertilization in crop sequences in entic hapludolls
(Asociación Argentina de la Ciencia del Suelo, 2016)Los contenidos de fósforo (P) extractable de la mayoría de los suelos de la región pampeana disminuyeron al intensificarse su extracción con cultivos y pasturas. Son frecuentes los sitios con limitaciones en P que requieren ... -
Changes in number and weight of wheat and triticale grains to manipulation in source-sink relationship
(Hindawi, 2019-01)The source-sink ratio experimental manipulation has helped to define whether a crop is limited by source or sink or co-limited by both. There is no evidence in triticale of source-sink manipulations effects on yield and ... -
Climate impacts on crop yields in Central Argentina. Adaptation strategies
(2018-02)The Pampas is among the major agricultural regions in the world; a large proportion of Argentina crop production is originated in this region. The exportation of grain and oil crop represents more than 40% of the total ... -
Drought tolerant wheat IND-ØØ412-7 is nutritionally equivalent to its Non-Transgenic Comparator
(Taylor & Francis, 2022-06)Expression of the HAHB4 sunflower transcription factor confers drought tolerance to wheat event IND-ØØ412-7 (HB4® wheat). After confirming the compositional equivalence of event IND-ØØ412-7 with conventional wheat, its ... -
Efectos de diferentes estrategias de fertilización sobre los rendimientos, el balance de nutrientes y su disponibilidad en los suelos en el largo plazo
(IPNI, 2015-09)A nivel productivo, las deficiencias de nitrógeno (N), fósforo (P) y azufre (S) no ocurren de manera aislada sino que se combinan de diversas maneras, por lo que es necesario evaluar integralmente la respuesta a la ... -
First report of spot lesion of wheat caused by Pyrenophora teres f. sp maculata observed in Argentina
(2019-08)Pyrenophora tritici-repentis, causal agent of tan spot, is the species commonly associated with leaf spotting symptoms on wheat (Triticum aestivum L.) worldwide and in Argentina. On the other hand, P. teres is a major ... -
Fruiting efficiency : an alternative trait to further rise wheat yield
(2015-07)Further improvements in wheat yields are critical, for which increases in grain number would be required. In the recent past, higher grain number was achieved through increased growth of the juvenile spikes before anthesis, ... -
Genomics-assisted breeding for quantitative disease resistances in small-grain cereals and maize
(MDPI, 2020-12-19)Generating genomics-driven knowledge opens a way to accelerate the resistance breeding process by family or population mapping and genomic selection. Important prerequisites are large populations that are genomically ... -
Higher than expected N2O emissions from soybean crops in the Pampas Region of Argentina: Estimates from DayCent simulations and field measurements
(Elsevier, 2022-08)In developing countries, agriculture generally represents a large fraction of GHG emissions reported in National Inventories, and emissions are typically estimated using Tier 1 IPCC guidelines. However, field data and ... -
Mejores prácticas de manejo de la fertilización de trigo : dos experiencias de INTA 9 de Julio
(2013-03)Las mejores prácticas de manejo (MPM) de uso de fertilizantes involucran aplicar la fuente de nutriente correcta, en la dosis, el momento y el lugar correctos. Estas decisiones son críticas para alcanzar una óptima eficiencia ... -
Photoperiod-sensitivity genes (Ppd-1) : quantifying their effect on the photoperiod response model in wheat
(Oxford University Press, 2019-10)Coupling anthesis date to the most suitable environmental conditions is critical for wheat (Triticum aestivum L.) adaptation and yield potential. Development to anthesis is controlled by temperature and photoperiod. Response ... -
Photoperiod-sensitivity genes shape floret development in wheat
(2019-02)Lengthening the pre-anthesis period of stem elongation (or late-reproductive phase, LRP) through altering photoperiod sensitivity has been suggested as a potential means to increase the number of fertile florets at anthesis ... -
Root phenotypes at maturity in diverse wheat and triticale genotypes grown in three field experiments: Relationships to shoot selection, biomass, grain yield, flowering time, and environment
(Elsevier, 2020-09)Modelling and limited data suggest that crops with deeper and longer roots capture more soil resources and yield more when water is available deeper in soil profiles. Interest has grown in the development of new cultivars ... -
Should farmers follow the recommendations of market advisory services? A hierarchical bayesian approach to estimation of expected performance
(Wiley, 2010-04-07)ABayesian hierarchical approach is employed to estimate individual expected performance of agricultural market advisory services. Skeptical beliefs based on market efficiency are incorporated as prior information. For a ... -
The physiology and genetics behind fruiting efficiency, a promising spike trait to improve wheat yield potential
(Oxford University Press, 2021-03)The fruiting efficiency (FE, grains per g of spike dry weight at anthesis) was proposed as a promising spike trait to improve wheat yield potential, based on its functional relationship with grain number determination (the ... -
Updated guidelines for gene nomenclature in wheat
(Springer Nature, 2023-03)The last decade has seen a proliferation in genomic resources for wheat, including reference- and pan-genome assemblies with gene annotations, which provide new opportunities to detect, characterise, and describe genes ... -
Variabilidad, tendencia y eventos extremos en los rendimientos agrícolas a nivel de partidos en la Provincia de Buenos Aires
(Facultad de Ciencias Económicas, Universidad de Buenos Aires, 2022-06-09)Climate variability is the main determinant of fluctuations in the productive and economic results of agriculture. Due to Climate Change, extreme events are expected to occur with greater frequency and intensity in the ... -
Wheat pre-anthesis development as affected by photoperiod sensitivity genes (Ppd-1) under contrasting photoperiods
