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 ... -
Shoot- and tuber-based critical nitrogen dilution curves for the prediction of the N status in potato
(Elsevier, 2020-09)Critical nitrogen (N) dilution curves describe the critical N concentration in plant tissues during crop growth and they are used to estimate the N nutriton status of whole plants in potato. Little is known, however, about ... -
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 ... -
Silo-bag system for storage of grains, seeds and by-products: A review and research agenda
(Elsevier, 2022-12)Silo-bags (grain bag, sausage bag or silo bolsa) have been used for storing grains in Argentina for more than 25 years, and are now fully integrated in the grain postharvest system at different levels with important economic ... -
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 ... -
Situación de las virosis del cultivo de papa en el Sudeste Bonaerense
(Ediciones INTA, 2022-04)En el sudeste de la provincia de Buenos Aires se encuentra la principal región productora de papa de la Argentina. La papa que se produce tiene tres destinos: el mercado fresco, la industria y la producción de semilla, la ... -
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, ... -
Soil organic carbon in cropping sequences with predominance of soya bean in the argentinean humid Pampas
(Wiley, 2020-01)Soya bean (Glycine max (L.) Merr.) monoculture can lead to a decrease in labile fractions of soil organic carbon (SOC). This study sought to evaluate the effects of cover crops (CC), application of fertilizer, and crop ... -
Sorghum biomass yield and allocation as affected by the combination of photoperiod sensitivity, sweet-stalk and brown midrib traits
(Elsevier, 2024-01)Context or problem: Traits like photoperiod sensitivity, sweet-stalk and brown midrib (bmr) have been introgressed to increase the biomass yield and quality of sorghum (Sorghum bicolor (L.) Moench) towards bioenergy yield ... -
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 ... -
