Selection for high spike fertility index increases genetic progress in grain yield and stability in bread wheat
(Springer Netherlands, 2018-07-18)Spike fertility index (SF) has been proposed as a promising trait to be used as a selection criterion in wheat breeding programs aimed at increasing grain yield, but no actual evidence of its successful application has ... -
Seminal plasma proteins interacting with sperm surface revert capacitation indicators in frozen-thawed ram sperm
(Elsevier, 2016-10)This study was conducted to evaluate the effects of interacting seminal plasma proteins (iSPP) obtained by AV or EE on frozen-thawed ram sperm in order to test the hypothesis whether this fraction could be sufficient to ... -
Short- and long-term responses to seasonal drought in ponderosa pines growing at different plantation densities in Patagonia, South America
(2012-12)Trees drought responses could be developed in the short- or in the long-term, aiming at sustaining carbon fixation and water use efficiency (WUE). The objective of this study was to examine short- and long-term adjustments ... -
Silicophytoliths from a Pampean native tree community (Celtis ehrenbergiana community) and their representation in the soil assemblage
(Elsevier, 2018-06)Plant phytolith production and their incorporation into soil assemblages has been studied by diverse authors indifferent regions of theworld,mainly in the Northern Hemisphere and Africa. However, these types of studies ... -
Sistemas de cultivo alternativos desarrollados por productores en el sudeste de la provincia de Buenos Aires
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2015-10-21)El proceso de expansión de la soja (denominado sojización) en la pampa argentina ha tenido como consecuencia la especialización de numerosas explotaciones agrícolas en el cultivo de soja. Sin embargo, muchos actores del ... -
Slaughter weight, sex and age effects on beef shear force and tenderness
(Elsevier, 2014-05)In Argentina, beef cattle prices decrease as slaughter weight increases regardless of animal age or carcass maturity, and this decrease is significantly greater in heifers (15%) than in steers (5%). The objectives of the ... -
Soil carbon dioxide and nitrous oxide emissions during the growing season from temperate maize‐soybean intercrops
(Wiley, 2012-06)The Argentine Pampa is one of the major global regions for the production of maize (Zea mays L.) and soybean (Glycine max L. [Merr.]), but intense management practices have led to soil degradation and amplified greenhouse‐gas ... -
Soil organic carbon changes simulated with the AMG model in a high-organic-matter Mollisol
(Sociedad Española de la Ciencia del Suelo, 2016)Soil organic carbon (SOC) management requires a precise knowledge of how it is affected by soil use. Simulation models could help for this purpose. The AMG model is simple, requires information that is easily available, ... -
Soybean and wheat response to lime in no-till Argentinean mollisols
(Elsevier, 2015-09)Crop production in Argentina has significantly increased over the past few years; this increase was consequence of better management practices which included P and N fertilization and, occasionally, S fertilization. Commonly ... -
Soybean shows an attenuated nitrogen dilution curve irrespective of maturity group and sowing date
(2016-02-01)It is generally accepted that the nitrogen (N) dilution curves relating shoot nitrogen concentration (%N) and shoot biomass (W) are similar among genotypes from the same species. However, differences in the pattern of ... -
Spatial and temporal variation in the migration of Ruddy-headed Goose in southern South America using satellite tagging
(Cambridge University Press, 2020-04-30)Ruddy-headed Goose Chloephaga rubidiceps is the smallest of the five South American sheldgeese and has two separate populations: one sedentary, which resides in the Malvinas/Falkland Islands and one migratory that overwinters ... -
Spongy Myelinopathy in Newborn Beef Calves Associated with Consumption of Corn Infected with Stenocarpella maydis
(Elsevier, 2019-10)Stillbirth and perinatal mortality with neurological signs and lesions were diagnosed in two calves following ingestion by their dams of corn infected with Stenocarpella maydis during the third trimester of gestation. ... -
Stand density management diagrams of Eucalyptus Viminalis: predicting stem volume, biomass and canopy cover for different production purposes
(Universidade Federal de Lavras, 2019-12-13)Stand density management diagrams (SDMD) provide a guide for forest density management taking into account stands attributes such as trees´ diameter or volume. One of the most common species planted in Pampean plains of ... -
Standard methods for fungal brood disease research = Métodos estándar para la investigación de enfermedades fúngicas de la cría
(Taylor & Francis, 2013)Chalkbrood and stonebrood are two fungal diseases associated with honey bee brood. Chalkbrood, caused by Ascosphaera apis, is a common and widespread disease that can result in severe reduction of emerging worker bees and ... -
Storage of WDGS under hermetic and non-hermetic conditions : effect on sensory properties, microorganisms, mycotoxins and nutritional value.
(Elsevier, 2019-01)WDGS production in Argentina substantially increased in the last 5 years and become a frequent constituent for feed diets. However, due to the extremely high moisture content of the product, quality deterioration occurs ... -
Sulfur affects root growth and improves nitrogen recovery and internal efficiency in wheat
