Assessment of the main sources of variability of soybean (Glycine max) expeller composition and quality: a field study
(International Commission of Agricultural and Biosystems Engineering, 2020-12-26)Pairs of soybean seeds and their correspondent expeller samples were collected from ten extrusion-expelling processing plants in Argentina. Seeds were analyzed for proximal composition, bulk moisture content (MC) and ... -
Control químico de Pythium spp. en plántulas de soja
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTAGerencia de Comunicación e Imagen Institucional; INTA, 2017-05-10)La podredumbre por Pythium en soja puede aparecer desde la germinación de la semilla hasta mediados de la época de crecimiento. Se evaluó la eficacia de control de cuatro fungicidas aplicados en forma preventiva en semillas ... -
Critical period for seed number determination in soybean as determined by crop growth rate, duration, and dry matter accumulation
(Elsevier, 2020-12-13)Seed number (SN) is positively associated with aboveground dry matter (ADM) accumulation in most crop species. In soybean, there are discrepancies among studies relative to the start and end of the critical period for seed ... -
Drought tolerance screening under controlled conditions predicts ranking of water‐limited yield of field‐grown soybean genotypes
(Wiley, 2015-04)Drought is a major limitation to crop yields worldwide. Screening for soybean yield under water deficit is often a bottleneck in breeding programmes. We assessed the validity of a standardized drought tolerance screening ... -
Drying of soybean seeds and effect on protein quality and oil extraction efficiency by extruding-expelling process
(Escola Superior de Agricultura Luiz de Queiroz (Brasil), 2023)Soybean seeds (Glycine max) were dried under real scale conditions to different final moisture content (m.c.) (9.1, 9.7, 10.9 %, and control with 16.2 %) and processed through extruding-expelling. Results indicated that ... -
Efecto de la fertilización nitrogenada en soja intersembrada en trigo en Balcarce
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2014-04)Es sabido que la soja intersembrada en trigo tiene bajo crecimiento inicial, lo cual podría afectar negativamente la formación de nódulos fijadores de nitrógeno (N) y limitar el crecimiento de la soja luego de la cosecha ... -
Efectos de Carbaryl y Metaldehído sobre Armadillidium vulgare (Crustacea: Isopoda) y Milax gagates (Mollusca: Pulmonata) en soja bajo siembra directa
(2014)Los objetivos fueron evaluar la eficacia de control y las dosis de los cebos Metaldehído 4% + Carbaryl 8% (2, 4 y 6 kg ha-1), Carbaryl 8 %, y Metaldehído 4 % y 5 % (2 y 4 kg ha-1) sobre Armadillidium vulgare y Milax gagates ... -
Effect of Diet Supplementation with Combinations of Soybean and Linseed Oils on Milk Production and Fatty Acid Profile in Lactating Dairy Ewes
(2018-02)Thirty-six Pampinta ewes were used in a completely randomized design to examine the effectiveness of soybean (SO) and linseed (LO) oils to reduce the concentration of the atherogenic fatty acids (FA) of milk (C12:0 to ... -
Effect of intensified cropping sequences on soil physical properties in contrasting environments
(Elsevier, 2021-08-27)Soybean (Glycine max (L.) Merr.) monoculture contributes to soil degradation. Intensification of soybean-based sequences through polyculture, cover crops (CC), and crop fertilization can enhance soil physical quality and ... -
Efficient Agrobacterium tumefaciens-mediated transformation system of Diaporthe caulivora
(Elsevier, 2021-03-10)This is the first report describing the genetic transformation of Diaporthe caulivora, the soybean stem canker fungus. A simple and 100% efficient protocol of Agrobacterium tumefaciens-mediated transformation used mycelium ... -
Gross nitrogen mineralization and immobilization in temperate maize-soybean intercrops
(Springer, 2015-06)Background and aims: Reliance on nitrogen (N) fertilizers to maintain crop productivity requires a thorough understanding of the transformation of this nutrient within the soil-plant system. Organic matter input from a ... -
Incorporación de cultivos de cobertura previos a soja en el sudeste bonaerense
(2013-06)En la zona del sudeste bonaerense existe escasa información sobre las eventuales ventajas de la incorporación de los CC en los planteos productivos actuales, la cual sería de suma utilidad para evaluar la factibilidad de ... -
Irrigation increases on-farm soybean yields in water-limited environments without a trade-off in seed protein concentration
(Elsevier, 2023-12-01)Context or problem: A trade-off between seed protein concentration (SPC) and yield has been reported for soybean. Therefore, assessing management practices that can nullify this trade-off is relevant to avoid further ... -
Land tenancy, soybean, actors and transformations in the pampas: A district balance
(2015-06)In Argentina, the recent expansion of agriculture has turned into an extreme process almost completely dominated by soybean. The magnitude and speed of soybean expansion are believed to be the main drivers behind social, ... -
