Maize grain yield components and source-sink relationship as affected by the delay in sowing date
(Elsevier, 2016-11)Delaying maize (Zea mays L.) sowing date can diminish grain yields through reductions in the number, size and activity of growing grains (sink strength) and/or reductions in the assimilate supply (source capacity) to grains ... -
Maize transpiration efficiency increases with N supply or higher plant densities
(Elsevier, 2021-03-08)Most of the studies addressing the influence of management practices on seasonal crop water use efficiency (i.e., the ratio between shoot biomass and evapotranspiration in a seasonal scale, WUE(B, ET, s)) have focused on ... -
Maize–soybean intensification alternatives for the Pampas
(2014-06)Cultivating multiple crops as a land use alternative could increase system productivity and sustainability, providing options to soybean monoculture for the Argentinean Pampas. This study evaluates the performance of ... -
Management effects on glyphosate and AMPA concentrations in the PM10 emitted by soils of the central semi-arid region of Argentina
(Elsevier, 2020-12)In soils of semi-arid regions, different amounts of glyphosate are applied, and this substance tends to be absorbed on the topsoil exposed to erosion. The objective of this study was to analyze the effects of land management ... -
Meat quality traits in the Greater rhea (Rhea americana) as influenced by muscle, sex and age
(2018-02)Meat from the Greater rhea (Rhea americana) could compete with traditional red meats, diversifying the market of protein products of animal origin. The meat from 32 rheas was used to study quality aspects and this included ... -
Methodological performance of selenium determination in ruminal fluid by hydride generation atomic absorption spectroscopy
(Ediciones INTA, 2021-04)Selenium (Se) is a trace element used by multiple enzymes. In ruminants, Se present in food is released to ruminal fluid allowing its absorption in the small intestine. Se release may be analysed by hydride generation ... -
Un método simple y práctico para la determinación de densidad aparente
(2014)La condición física del suelo es fundamental para definir su calidad/salud y es afectada por el uso. Por ello, es necesario el seguimiento de los cambios en la condición física de los suelos bajo producción, a través de ... -
Métodos agronómicos y ambientales de determinación de fósforo en argiudoles del sudeste bonaerense = Agronomic and environmental phosphorus determinations in argiudolls of southeast of Buenos Aires
(2015-03-25)Los análisis de suelo son herramientas útiles para evaluar la fertilidad edáfica y efectuar recomendaciones de fertilización (métodos agronómicos). Otros métodos, denominados ambientales, estiman el fósforo (P) que puede ... -
Métodos de colocación de fósforo en trigo y maíz bajo siembra directa en el sudeste bonaerense
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2018-12)La siembra directa (SD) produce cambios físicos, químicos y biológicos en el suelo que pueden afectar la disponibilidad de P para los cultivos. El uso eficiente de fertilizantes debe combinar factores como dosis, momento, ... -
Microsatellite genotyping reveals extensive genetic diversity in bovine Neospora caninum from the humid Pampa region in Argentina
(Springer Verlag, 2020-10-15)Neospora caninum is an apicomplexan protozoan and a major cause of abortion in cattle worldwide. In the Argentinian Humid Pampa, bovine neosporosis causes severe economic losses. Despite this, information on the genetic ... -
Mid-Season High-Resolution Satellite Imagery for Forecasting Site-Specific Corn Yield
(MDPI, 2016-10)A timely and accurate crop yield forecast is crucial to make better decisions on crop management, marketing, and storage by assessing ahead and implementing based on expected crop performance. The objective of this study ... -
Milk fatty acid profile from grazing buffaloes fed a blend of soybean and linseed oils
(Escola de Veterinária, Universidade Federal de Minas Gerais, 2015-06)The aim of the study was to examine the changes in milk fatty acid (FA) profile of grazing buffaloes fed either low (L, 276g/d) or high (H, 572g/d) doses of a blend (70:30, wt/wt) of soybean and linseed oils. Fourteen ... -
Modelación de la calidad nutritiva de pasturas defoliadas
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2016-11-30)El objetivo del trabajo fue desarrollar un modelo de simulación de calidad foliar de pasturas, de base morfogenética, para integrar el efecto de la edad y el largo foliar sobre la digestibilidad en relación con el manejo ... -
