Cover crop mixtures increase ecosystem multifunctionality in summer crop rotations with low N fertilization
(Springer Nature, 2022)Cropping diversification with cover crop mixtures combined with low N fertilization represents an ecological alternative that may promote sustainability. Our objective was to evaluate changes on soil organic fractions and ... -
Organic agriculture in Argentina’s Pampas. A case study on Pampa Orgánica Norte farmers
(Cambridge University Press, 2022-02)Faced with a society that demands the reduction of negative environmental impacts of agriculture while producing high-value, healthy food for local and export markets, Argentina is currently in a debate on the alternative ... -
Unravelling the complexity of maize resistance to bacterial and fungal diseases: an integrative perspective
(Springer Nature, 2022-02)Maize is one of the most important cereals for both human and animal nutrition, and diseases that affect the crop pose a major threat to global food security. Breeders are racing against time to develop genotypes resistant ... -
Breeding effects on canopy light attenuation in maize: a retrospective and prospective analysis
(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 ... -
Environment affects starch composition and kernel hardness in temperate maize
(Wiley, 2022-03)BACKGROUND: Protein percentage and kernel weight affect the endosperm hardness of maize grains. However, changes in starch composition could also modify kernel hardness, which is often predicted through milling ratio. The ... -
Detecting sources of resistance to multiple diseases in Argentine maize (Zea mays L.) germplasm
(Springer Nature, 2022-04)Maize (Zea mays L.), an important cereal for human and animal nutrition, is usually affected by multiple co-occurring pathogens that reduce production. Argentina is the fourth maize producer worldwide, with common rust ... -
Sistemas socioeconómicos : círculos de información en función del tiempo
(Instituto Argentino para el Desarrollo Económico - IADE, 2022-04)La teoría económica competitiva provee la estructura del mercado ideal. El paradigma neoclásico plantea el supuesto de la información disponible completa y gratuita. No obstante, abundante evidencia empírica demuestra que ... -
Expressing the sunflower transcription factor HaHB11 in maize improves waterlogging and defoliation tolerance
(Oxford University Press, 2022-05)The sunflower (Helianthus annuus) transcription factor HaHB11 (H. annuus Homeobox 11) belongs to the homeodomain-leucine zipper family and confers improved yield to maize (Zea mays) hybrids (HiII × B73) and lines. Here we ... -
Maize genetic progress in the central Pampas of Argentina: effects of contrasting sowing dates
(Elsevier, 2022-05)Delayed sowing date of maize (Zea mays L.) has become a broadly adopted practice in the Pampas region of Argentina, because late-sown crops frequently experience a more favorable water balance around flowering and a reduction ... -
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 ... -
Cane molasses and oligofructose in the diet of laying hens improves the mineral content of eggs and meat
(Elsevier, 2022-06)Poultry-based foods contribute to human health due to their high nutrient value. Previously, it was shown that short-chain fatty acids (SCFAs) produced by in vitro intestinal fermentation of a molasses and oligofructose ... -
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 ... -
Efecto del secado y manejo agronómico sobre propiedades físicas asociadas a la dureza del grano en híbridos de maíz
(Universidad Tecnológica Nacional, Argentina, 2022-06-22)Se evaluó el efecto de distintos tratamientos de secado (natural, 50 y 70 °C) y manejo agronómico (sin y con re-fertilización en pre-floración) sobre la dureza endospérmica en cuatro híbridos de maíz (AW 190, NK 940, Cóndor ... -
Overcoming seed dormancy of junglerice (Echinochloa colona)
(Universidad de Concepción (Chile), 2022-08)Junglerice (Echinochloa colona L. Link) seed dormancy can persist 8 months after harvest and, once overcome, seeds can germinate over a long period of time. Light or high temperatures could overcome seed dormancy, while ... -
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 ... -
